Abstract
A electrochemical cell system includes a fluid manifold having a layered structure. The fluid manifold includes at least one conduit layer having a first side and a second side. The at least one conduit layer has at least one conduit channel.
Description
- The present document relates to fluid management technology. More specifically, it relates to a fluid manifold.
- Trends in technology are progressing towards smaller scales for systems in a variety of applications. Fluidic systems can be integrated within restrictive form factors imposed by the system to manipulate the transport of fluid. For example, flow-modulating components can be arranged for functions such as reactant delivery, heat transfer, and dosing of fluids.
- Electronic components, such as personal electronic devices, are trending to become smaller in size. As electronic components are designed in smaller in size and incorporate sophisticated and complex technology, the demands on the power supply become greater. For instance, the power supply may need to occupy less volume or a smaller footprint to accommodate the addition of the technology to the device. The additional technology may also require that the power supply last for longer periods of time. In addition, portable electronic device may need to have energy storage maintained while the power supply shrinks.
- An example of a power supply for the electronic components is a electrochemical cell system. In order to make a smaller electrochemical cell system, many individual components of the system, such as a fluid delivery component can be made smaller, but need to meet the technical requirements of the electrochemical cell system. For instance, the fluid delivery component may need to maintain a certain pressure, without occupying an overall significant volume of the electrochemical cell system, and without interfering with the assembly of the electrochemical cell system. Furthermore, the functionality of the electrochemical cell system must not be compromised.

The drawings show, by way of illustration, specific embodiments in which the fluid manifold and fuel cell fuel systems and methods may be practiced. These embodiments, which are also referred to herein as “examples” or “options,” are described in enough detail to enable those skilled in the art to practice the present invention. The embodiments may be combined, other embodiments may be utilized or structural or logical changes may be made without departing from the scope of the invention. The following detailed description is, therefore, not to be taken in a limiting sense and the scope of the invention is defined by the appended claims and their legal equivalents.
- In this document, the terms “a” or “an” are used to include one or more than one, and the term “or” is used to refer to a nonexclusive “or” unless otherwise indicated. In addition, it is to be understood that the phraseology or terminology employed herein, and not otherwise defined, is for the purpose of description only and not of limitation.
- A fluid manifold is provided herein. In the following examples, a fuel manifold for a electrochemical cell system is discussed. However, the fluid manifold is not necessarily so limited and can be used in other types of fluidic control systems or other types of systems in need of fluid management. For instance, the fluid manifold can be used to deliver or remove other types of fluids, including, but not limited to water, oxidant, or a heat transfer fluid. For instance, the fluid manifold includes, but is not limited to, a fuel manifold, a heat transfer manifold, an oxidant manifold, or a water removal manifold.
- As used herein, “fluid” refers to a continuous, amorphous substance whose molecules move freely past one another and that has the tendency to assume the shape of its container. A fluid may be a gas, liquefied gas, liquid or liquid under pressure. Examples of fluids may include fluid reactants, fuels, oxidants, and heat transfer fluids. Fluid fuels used in fuel cells may include hydrogen gas or liquid and hydrogen carriers in any suitable fluid form.

- As used herein, “fluid enclosure” may refer to a device for storing a fluid. The fluid enclosure may store a fluid physically or chemically. For example, the fluid enclosure may chemically store a fluid in active material particles.
- As used herein, “active material particles” refer to material particles capable of storing hydrogen or other fluids or to material particles that may occlude and desorb hydrogen or another fluid. Active material particles may include fluid-storing materials that occlude fluid, such as hydrogen, by chemisorption, physisorption or a combination thereof. Some hydrogen-storing materials desorb hydrogen in response to stimuli, such as change in temperature, change in heat or a change in pressure. Examples of hydrogen-storing materials that release hydrogen in response to stimuli, include metal hydrides, chemical hydrides, suitable micro-ceramics, nano-ceramics, boron nitride nanotubes, metal organic frameworks, palladium-containing materials, zeolites, silicas, aluminas, graphite, and carbon-based reversible fluid-storing materials such as suitable carbon nanotubes, carbon fibers, carbon aerogels, and activated carbon, nano-structured carbons or any combination thereof.

A fluid may contact an enclosure, in which the fluid is physically forced inside the enclosure, for example.
- As used herein, “composite fluid storage material” refers to active material particles mixed with a binder, wherein the binder immobilizes the active material particles sufficient to maintain relative spatial relationships between the active material particles. Examples of composite fluid storage materials are found in commonly-owned U.S. patent application Ser. No. 11/379,970, filed Apr. 24, 2006, whose disclosure is incorporated by reference herein in its entirety. An example of a composite fluid storage material is a composite hydrogen storage material.
- Referring to
FIG. 1 , an example of an electrochemical cell system, such as aelectrochemical cell system 100 is shown. Although the term electrochemical cell system is used herein, it should be noted that the system can be used for any electrochemical cell system. Theelectrochemical cell system 100 includes one or more of afuel cell 102, a fuelcell fuel system 104, acharge port 106, andfuel storage 108. The fuelcell fuel system 104 includes a layered structure including, but not limited to, at least one pressure regulator, at least one check valve, at least one flow valve. In an option, the at least one pressure regulator, the at least one check valve, at least oneflow valve 106 include featured layers that are stacked together and operatively interact together, for example as discussed in co-pending application entitled “FLUIDIC CONTROL SYSTEM AND METHOD OF MANUFACTURE”, filed even date herewith, having attorney docket number 2269.061US1, and is incorporated herein by reference in its entirety. Theelectrochemical cell system 100 further includes a manifold 118, such as afuel manifold 120 fluidly coupled with afluid enclosure 114, such as thefuel storage 108. The manifold 118 is also fluidly coupled with thefuel cell 102. The fluid coupling for the fuel manifold and the fuel storage can include, but is not limited to compression seals, adhesive bonds, or solder connections. Although a fuel manifold is discussed as an example, the manifold can also be used to distribute, deliver, or remove other types of fluids, such as, but not limited to water, oxidant, or a cooling fluid. - Devices for detachably coupling the fluid coupling, such as a pressure activated valve, can be used. For example, pressure activated one-way valve allows a flow of fluid, for example, fluid fuel, into a fluid enclosure for a fuel storage system. The flow of fuel is allowed into a fluid reservoir during refueling, but does not allow fuel to flow back out of the fuel reservoir. In an option, flow of fuel is permitted to flow back out of the fluid reservoir if the fluid reservoir is over pressurized with fuel.
- An external refueling device can form a seal against a portion of the sealing surface, for example, around the inlet port with a seal, such as an o-ring or gasket. Fuel is introduced into the fluid control system, and the fluidic pressure of the fuel compresses the compressible member and breaks the seal between the compressible member and the outside cover. In another option, an environment surrounding the exterior of the outside cover may be pressurized with fuel to force fuel through the refueling valve assembly and into the fuel reservoir.
- When the fueling process is complete, the refueling fixture is removed from the valve assembly, and the valve becomes closed. For example, the compressible member decompresses, and fluidic pressure from the fuel reservoir through the fuel outlet port exerts pressure on to the compressible member and presses the compressible member against the outside cover. The decompression of the compressible member and/or the fluid pressure from the reservoir creates a seal between the compressible member and the outside cover such that fuel does not flow past the compressible member and into the fuel inlet port. In another option, the compressible member and/or the fluid diffusion member can be designed to intentionally fail if the pressure in the fuel reservoir becomes too great, or greater than a predetermine amount. Additional examples and details of valves can be found in commonly owned co-pending patent application entitled REFUELING VALVE FOR A FUEL STORAGE SYSTEM AND METHOD THEREFOR, filed on Jan. 9, 2007, having Ser. No. 11/621,542, and attorney docket no. 2269.003US1, which is incorporated by reference in its entirety.
- In another option, a fluid coupling assembly can be used to couple the system with another component. The coupling assembly includes a first coupling member, a second coupling member, and a seal member therebetween. The first coupling member and the second coupling member are magnetically engagable, such as by way of a first magnetic member and a second magnetic member having attracted polarities. The engagement of the first coupling member and the second coupling member opens a fluid flow path therebetween. When the coupling members are disengaged, this fluid flow path is sealed. Additional examples and details can be found in commonly owned co-pending entitled MAGNETIC FLUID COUPLING ASSEMBLIES AND METHODS, filed Nov. 7, 2007, having Ser. No. 11/936,662, and having attorney docket no. 2269.056US1, which is incorporated herein by reference in its entirety.
- In a further option, the system includes a
strain absorbing interface 404 for contacting the fluid enclosure. For instance, the interface is used for a rigid or semi-rigid component and a flexible fluid enclosure. The interface absorbs any strain due to dimensional changes in the fluid enclosure as it charges with hydrogen. Rigid components, such as mounts or fluidic devices for fuel cell communication, can be coupled to the fluid enclosure through the flexible interface and not risk sheering due to mechanical stress. The flexible interface allows for more component configurations and applications for use with a flexible fluid enclosure. The flexible interface absorbs strain and supports the connection between component and enclosure. Additional examples and details can be found in commonly owned co-pending patent application entitled INTERFACE FOR FLEXIBLE FLUID ENCLOSURES, filed even date herewith, having Ser. No. ______, and having attorney docket no. 2269.063US1, which is incorporated herein by reference in its entirety. - Referring to
FIG. 6 , a cross-sectional view of a flexible fluidenclosure interface system 400 is shown, according to some embodiments. Thesystem 400 includes a flexiblefluid enclosure 406 in contact with astrain absorbing interface 404 on a first side. On a second side, theinterface 404 may be in contact with a featuredlayer 402. The featured layer may include a plurality of featured layers, or one or more featured layers that collectively form a functional control system component. Anoptional fluidic connection 408 may be positioned in theinterface 404, connecting theenclosure 406 and featuredlayer 402. - The fluid enclosure may be flexible. For example, a flexible fluid enclosure may include a flexible liner for storing a fluid. The fluid enclosure can include fuel cartridges, such as replaceable fuel cartridges, dispenser cartridges, disposable fuel ampoules, refillable fuel tanks or fuel cell cartridges, for example. The fuel cartridge may include a flexible liner that is connectable to a fuel cell or fuel cell layer. The fuel cartridge may also include a connecting valve for connecting the cartridge to a fuel cell, fuel cell layer or refilling device. The
fluid enclosure 406 may be an enclosure formed by conformably coupling an outer wall to a composite hydrogen storage material, for example. - Conformably coupled refers to forming a bond that is substantially uniform between two components and are attached in such as way as to chemically or physically bind in a corresponding shape or form. A structural filler or composite hydrogen storage material may be conformably coupled to an outer enclosure wall, for example, in which the outer enclosure wall chemically or physically binds to the structural filler or composite hydrogen storage material and takes its shape. The outer enclosure wall is the outermost layer within a fluid enclosure that serves to at least partially slow the diffusion of a fluid from the enclosure. The outer enclosure wall may include multiple layers of the same or differing materials. The outer enclosure wall may include a polymer or a metal, for example. The fluid may be hydrogen, for example. Examples of such enclosures may be found in commonly owned U.S. patent application Ser. No. 11/473,591, filed Jun. 23, 2006.
- The
strain absorbing interface 404 may be manufactured of any suitable material that allows it to be flexible, absorb strain and bond to theenclosure 406 and featuredlayer 402. The material chosen should provide a suitable bond, physical or chemical, between the featuredlayer 402 andenclosure 406 and also allow for the differential in strain between the strain of the enclosure wall and the rigidity of the featuredlayer 402, so that the sheer stress on any bonds does not exceed the strength of such bonds. Theinterface 404 may be manufactured of an elastomeric material or silicon material, for example. Elastomeric materials may include thermoplastic elastomers, polyurethane thermoplastic elastomers, polyamides, melt processable rubber, thermoplastic vulcanizate, synthetic rubber and natural rubber, for example. Examples of synthetic rubber materials may include nitrile rubber, fluoroelastomers such as Viton® rubber (available from E.I. DuPont de Nemours, a Delaware corporation), ethylene propylene diene monomer rubber (EPDM rubber), styrene butadiene rubber (SBR), and Fluorocarbon rubber (FKM). - As the
fluid enclosure 406 is filled with fluid, or charged, the dimensions of theenclosure 406 increase (seeFIG. 7 ). Thestrain absorbing interface 406 may deform or change in dimension, such as inthickness 412. Thestrained interface 414 then maintains a consistent, less stressful contact between theenclosure 406 and featuredlayer 402. The featuredlayer 402 would then undergo little to no strain, as theinterface 414 absorbs strain caused by theenclosure 406 movements. Theinterface 414 may absorb all or at least part of the strain caused by changes in dimension ofenclosure 406. - The featured
layer 402 may be any fitting, mount, connector, valve, regulator, pressure relief device, planar microfluidic device, a plate, or any device that might control the flow of a fluid from the fluid enclosure into or out of the enclosure or combinations thereof, for example. Examples of fluids include, but are not limited to, gas, liquefied gas, liquid or liquid under pressure. Examples of fluids may include fluid reactants, fuels, oxidants, and heat transfer fluids. Fluid fuels used in fuel cells may include hydrogen gas or liquid and hydrogen carriers in any suitable fluid form.Multiple interfaces 404 and multiple featuredlayers 402 may be utilized in conjunction with one or morefluid enclosures 406, where the featured layers form functional components such as, but not limited to, the fluidic control system, the manifold, the pressure regulator, the check valve. In another option, theinterfaces 404 can be coupled with an inlet of the fluidic control system, the fuel cell, or the fluidic enclosure. -
FIG. 1B illustrates additional examples for themanifold 118. Afuel cell assembly 100 includes afluid enclosure 114 fluidly coupled with a fluidic controller, such as apressure regulator component 116 by amanifold 118. The one or more fluid control components can include, but are not limited to a fluidic control system, inlets, outlets, a check valve component, a flow valve component, a charge valve component, a pressure relief component, a conduit, an on/off valve, a manual on/off valve, or a thermal relief component. - The
pressure regulator 116 is fluidly coupled with afuel cell 102 via amanifold 118. The manifold 118 includes one ormore conduit channels 130 therein. In a further option, the manifold 118 fluidly coupled with thepressure regulator component 116 and thefuel cell 102 can further include at least onefeedback channel 129 and adelivery channel 133. Thedelivery channel 133 delivers fluid such as a fuel to thefuel cell 102. Thefeedback channel 129 allows for the regulator to be piloted based on the feedback to thepressure regulator component 116 from pressure in the fuel plenum, and is fluidly coupled to a fluid plenum of the electrochemical cell system. Additional examples and details can be found in commonly owned co-pending patent application entitled FLUIDIC DISTRIBUTION SYSTEM AND RELATED METHODS, filed even date herewith, having Ser. No. ______, and having attorney docket no. 2269.067US1, which is incorporated by reference in its entirety. - Each of the components of the
electrochemical cell system 100 can be formed by the flexible layered structured as discussed above and below. In a further option, the one ormore conduit channels 130 include a gas conduit channel. Multiple ports, channels, including conduit channels or delivery channels are possible, such as shown inFIGS. 5 and 6 . - Referring to
FIG. 2 , the manifold 118, such as thefuel manifold 120, includes a layered structure formed of multiple, thin, flexible featured layers. The layered structure is made small, nano-fabrication technologies, and/or micro fabrication technologies can be employed to produce and assemble the layers. For instance, processes for producing and/or assembling the layers include, but are not limited to, microfluics application processes, or chemical vapor deposition for forming a mask, and followed by a process such as etching. In addition, materials for use in fabricating the thin layered structure includes, but is not limited to, silicon, polydimethylsiloxiane, parylene, or combinations thereof. - The featured layers include one or more features. In an option, the featured layers of the layered structure provides a gas-tight seal such that the featured layers are gas-tight. For example, a bond is provided with the layers that is impermeable to a fluid. In another example, the bond may be substantially impermeable to hydrogen or any other fluid at or below 350 psi or 2.5 MPa. Examples of fluids include, but are not limited to, hydrogen, methanol, formic acid, butane, borohydrides, water, air, or combinations thereof. In another option, the bond is substantially impermeable to fluid at or below 150 psi or 1.03 MPa. In yet another option, the bond is substantially impermeable to fluid at or below 15-30 psi or 0.10-0.21 MPa. The layered structure allows for the manifold to be of a size that does not take up unnecessary volume, nor an unnecessarily large footprint, yet allows for the pressure, volume, and temperature requirements for fuel cell fuel supply systems to be met. The multiple layers can be coupled together by thermal bonding, adhesives, soldering, ultrasonic welding, etc.
- The manifold 118 can be made of relatively thin layers of material, allowing for the manifold 118 to be flexible. In an option, the manifold 118, and/or the featured layers that make up the manifold 118, such as, but not limited to the
conduit layer 122 and/or the barrier layer, are flexible enough to have a bend radius of about 1-5 mm. In a further option, the manifold 180, and/or the featured layers, and/or theconduit layer 122, and/or the barrier layer have a bend radius of no less than about twice a thickness of a single featured layer, where the thickness is optionally less than 1 mm to 200 microns. The flexible manifold can be bent around components, or wrapped around components, providing greater number of assembly options for the electrochemical cell system. - The
fluid manifold 118 includes at least one featured layer, such as aconduit layer 122 defined in part by afirst side 124 and asecond side 126. In an option, the at least oneconduit layer 122 is relatively thin, for example, compared with the length and width. In an example, the thickness of the at least oneconduit layer 122 is generally less than about 1 mm. In another example, the thickness of the at least oneconduit layer 122 is about 5 μm-1 mm. In an example, the width and length of thelayer 122 is about 1 mm and 100 mm, respectively. In another example, the thickness of the at least oneconduit layer 122 is about 100 μm, and the width and length of thelayer 122 is about 1 mm and 1.5 mm, respectively. The width and/or the length can be altered for geometry of the system in which themanifold 118 is installed. - In a further option, the thickness of the layer is about 10-500 micron, and a dimension of the conduit channel, such as a height or a width or a channel depth, is about 50 micron to 1 mm. The layer is highly planar such that a width of the manifold is greater than about thirty times the dimension of the conduit channel. In another option, the width of the planar portion of the manifold is greater than three times the dimension of the conduit channel.
- The at least one
conduit layer 122 includes at least oneconduit channel 130 therein. In an option, theconduit layer 122 includes a plurality ofconduit channels 130 in theconduit layer 122, and in a further option, in each of the conduit layers 122. The plurality ofconduit channels 130 are disposed adjacent one another in a single layer. The at least oneconduit channel 130 can also be a recess or a partial recess or channel, and is a conduit channel that allows for material such as a fluid to flows therethrough. The at least oneconduit channel 130, in an option, extends through theconduit layer 122, from thefirst side 124 to thesecond side 126, as shown inFIG. 2 andFIG. 3A . In another option, the at least oneconduit channel 130 extends only partially within a side of theconduit layer 122, as shown inFIG. 3B . In yet another option, theconduit layer 122 includes two ormore conduit channels 130, within a single conduit layer. For example, two ormore conduit channels 130 which extend from thefirst side 124 to thesecond side 126 can be disposed within theconduit layer 122, as shown inFIG. 4 . The two ormore conduit channels 130 can include recesses that extend partially within a side of the conduit layer 122 (FIG. 3B ) and/or theconduit channels 130 can extend through the layer 122 (i.e. from thefirst side 124 and through the second side 126). Theconduit channels 130 that extend partially within the featured layer, optionally can be fluidly coupled with one another. - The two or
more conduit channels 130 can be formed within the featured layer such as theconduit layer 122 such that they do not intersect with one another in theconduit layer 122. Alternatively, the two ofmore conduit channels 130 can be formed within featured layer such as theconduit layer 122 such that they do intersect with one another or are fluidly coupled in theconduit layer 122. Theconduit channel 130 extends along theconduit layer 122, and allows for material such as fluid or fuel to flow therethrough. In an option, theconduit channels 130 and/or ports are sized and positioned so that flow therethrough is non-restrictive, which can be combined with any of the embodiments discussed above or below. For example, theconduit channels 130 and/or ports are sized similarly throughout the manifold so that flow therethrough is not restricted by changing the cross-sectional size of the channels or ports. In a further option, the conduit channels are delivery channels, where the channels deliver fluid such as a fuel. In a further option, the conduit channels include a feedback channel, for example for varying actuation of a regulator based on the pressure in a fuel cell fuel plenum. In yet another option, the conduit channel is a gas conduit channel. - In a further option, the conduit channel includes a channel having a surface allowing for non-restrictive flow. For example, the conduit channel has a surface roughness that is 1/50th of the hydraulic diameter of the channel. In a further option, the fluid for the conduit channel includes a gas, such as a low viscosity fluid that reduces inhibitive capabilities of the channels, including, but not limited to, hydrogen.
- In another option, a conduit channel such as a
first recess 132 can be formed on thefirst side 124 of theconduit layer 122, and asecond recess 134 can be formed on thesecond side 126 of theconduit layer 122, where thefirst recess 132 and thesecond recess 134 do not necessarily extend from thefirst side 124 through to thesecond side 126. In an example shown inFIG. 3C , the partial conduit channels or recesses 136 are disposed on opposite sides of theconduit layer 122, allowing for material to travel therethrough via the recesses on thefirst side 124 and thesecond side 126. - The
conduit layer 122, in another option, is formed of metals, plastics, elastomers, or composites, or a combination thereof. The at least oneconduit channel 130 is formed within and/or through thelayer 122, in an option. For example, the at least oneconduit channel 130 can be etched or stamped on, within and/or through thelayer 122. In another option, the at least oneconduit channel 130 can be drilled within and/or through the layer, formed with a laser, molded in thelayer 122, die cutting thelayer 122, or machined within and/or through thelayer 122. In an option, the at least oneconduit channel 130 has a width of about 5 to 50 times the depth of the recess. In another option, the at least oneconduit channel 130 has a width of about 1 mm-2 mm. In yet another option, the at least one recess has a width of about 50-100 μm. - One of the featured layers of the manifold 118 further optionally includes at least one
barrier layer 140, as shown inFIG. 2 . The barrier layer defines a portion of theconduit channels 130, for instance a wall portion of theconduit channel 130. In a further option, the manifold 118 includes afirst barrier layer 142 and asecond barrier layer 144 disposed on opposite sides of theconduit layer 122. For example, thefirst barrier layer 142 abuts and seals against thefirst side 124 of theconduit layer 122, and thesecond barrier layer 144 abuts and seals against thesecond side 126 of theconduit layer 122. This allows for theconduit channel 130 to be enclosed and form a conduit through which material travels. The barrier layers 142, 144 can be coupled with theconduit layer 122, for example, but not limited to, using adhesives, bonding techniques, or laser welding. In a further option, the barrier layers 142, 144 and a featured layer such as theconduit layer 122 are stacked together, and further optionally sealed together. For example, thelayers - The
layers - In a further option, the featured layers can form one or more of the barrier layers 142, 144 including one or
more ports 150 therein. For example, the one ormore ports 150 can include aninlet 152 and anoutlet 154. The inlet andoutlet barrier layer 144 such that they are fluidly coupled with theconduit channel 130. For example, the inlet and/oroutlet FIGS. 2 and 4 . Material such as fluid fuel can travel in through theinlet 152, through theconduit channel 130, and out of theoutlet 154. The one ormore ports 150 provide fluid communication between the manifold 118 and components to which themanifold 120 is coupled, such as, but not limited to, a fluid enclosure such as the fuel storage 108 (FIG. 1 ) or the fuel cell 102 (FIG. 1 ). The one ormore ports 150 can further provide fluid communication within themanifold 118, for example, between various featured layers. It should be noted that it is possible to use the manifold 118 as a fluid distribution system where there is a single inlet and multiple outlets so that the manifold 118 feeds multiple locations, for example on a fuel cell layer. The fluids usable with the manifold 118 include, but are not limited to: fuel, water, coolant, or oxidant. Examples of fluids which may be used could include, but are not limited to: hydrogen, methanol, ethanol, butane, formic acid, borohydride compounds, such as sodium and potassium borohydride, and aqueous solutions thereof, ammonia, hydrazine, silanes, or combinations thereof. - In a further option, a
filter element 131 can be incorporated into a part of the flow path. For example, thefilter element 131 can be disposed within theconduit channel 130, as shown inFIG. 3A . In another option, thefilter element 131 can be disposed within theports 150, such as theinlet 152. Thefilter element 131 can include a porous substrate or a flow constricting element. In another option, thefilter element 131 can define theconduit channel 130. Thefilter element 131 disposed within theconduit channel 130 and/or theports 150 assists in preventing collapsing of theconduit channel 130 and/orport 150 for instance, when thefuel manifold 120 is bent around itself or other components within the fuel cell assembly. In a further option, theconduit channel 130 extends along theconduit layer 122, and theconduit channel 130 is defined by a length. Thefilter element 131, in an option, extends along a portion, or the entire length of theconduit channel 130. In an option, thefilter element 131 is a porous substrate. -
FIGS. 4 and 5 illustrate additional options for the manifold 118, where the fluid manifold includes multiple featured layers. Referring toFIG. 4 , thefuel manifold 120 includes the at least oneconduit layer 122, afirst barrier layer 142, and asecond barrier layer 144. Thefirst barrier layer 142 and thesecond barrier layer 144 include one ormore ports 150 therein. The at least oneconduit layer 122 includes conduit channels such as afirst recess 132, asecond recess 134, and a third recess 136. The first, second, andthird recesses conduit layer 122, and line up with their respective ports when the layers are stacked together, such that there is fluid communication. The barrier layers 142, 144 can be coupled with theconduit layer 122 using, for example, but not limited to, adhesives, bonding techniques, or laser welding. in a further option, the barrier layers 142, 144 and theconduit layer 122 are sealed together. -
FIG. 5 illustrates another example of a manifold 118, which also includes multiple featured layers. For instance, the manifold 118 includes multiple featured layers including at least two conduit layers 122, afirst barrier layer 142, asecond barrier layer 144, and athird barrier layer 146. The conduit layers 122 for the various embodiments herein can serve as a barrier layer and conduit layer, and various features such as ports or conduit channels, or partially recessed channels can be formed in one or more of the featured layers, alone or in combination. The layers include at least one conduit channel. The conduit channel includes, but is not limited to a delivery channel, or a feedback channel. - A first conduit layer is disposed between the
first barrier layer 142 and the second barrier layer, and a second conduit layer is disposed between thesecond barrier layer 144 and thethird barrier layer 146. It should be noted that additional layers, including conduit layers and barrier layers could be incorporated into the manifold 118 for additional material flow options. - The
first barrier layer 142 and/or thesecond barrier layer 144 include one ormore ports 150 therein. It is possible for thethird barrier layer 146 to further include one ormore ports 150 therein. Theports 150 allow for material to flow in to and out of the manifold 120, and further to flow between the multiple conduit layers 122. The at least oneconduit layer 122 includes one or more recesses therein 130. The multiple recesses align with their respective ports when the layers are brought together, for example, by stacking the layers together and optionally sealing the layers. - The barrier layers 142, 144, 146 can be coupled with the conduit layers 122, for example, but not limited to, adhesives, bonding techniques, or laser welding. In a further option, the barrier layers 142, 144, 146 and the conduit layers 122 are sealed together. The various layers, including the featured layers and/or the barrier layers and/or the conduit layers allow for a flow path. In an option, a first flow path allows for fluid, such as gas, to be distributed on two more layers, where the first flow path extends from a first featured layer to a second featured layer. In yet another option, the flow path returns from the second featured layer to the first featured layer. In still another option, the first flow path circumnavigates a second flow path.
- The fluid manifold provides a layered structure allowing for fuel distribution in a relatively small amount of space. For example, the fuel system can be made with an overall thickness of about 50-100 μm, or in another example the overall thickness is about 20-100 μm. The fuel cell fuel manifold further allows for the transport of fuel, such as gas, while maintaining certain levels of pressure. For instance, hydrogen gas can be distributed through the layered structure of the fuel manifold while pressure in the range of 2-10 psig.
- The fluid manifold interacts with or can be coupled to the fuel cell or other system components using adhesives working over comparatively large surface areas to that the force due to internal fluidic pressures that is forcing the components apart is easily overcome by the strength of the adhesive bond. A high internal pressure can be counteracted with a bond that has a relatively low tensile strength.
- A method includes introducing fluid, such as a fuel, into a fluid manifold, the manifold including two or more featured layers each having a plurality of conduit channels. In an example, the fuel includes a gas or a liquid such as, but not limited to, hydrogen, hydrogen, methanol, ammonia, silanes, formic acid butane, or borohydrides. The method further includes flowing fluid through the conduit channels. The conduit channels include, but are not limited to, fuel channels, feedback channels, or delivery channels.
- Several options for the method are as follows. For instance, the method optionally includes providing fuel to a fuel cell assembly, where the fluid manifold is fluidly coupled with the fuel cell. The method optionally includes flowing material from a first layer recess of a first conduit layer to a second layer recess of a second conduit layer, and/or flowing material through a porous substrate within at least one of the one or more conduit channels, and/or providing a heat transfer fluid to a electrochemical cell system through the conduit channels. The method further optionally includes providing oxidant to a electrochemical cell system through the conduit channels or removing water from the electrochemical cell system through the conduit channels.
- Further options for the method are as follows. For instance, flowing fluid through one or more conduit channels includes flowing fluid along a partially recessed channel in the conduit layer, and/or flowing fluid through one or more conduit channels includes directing material along a first partial channel in the first side and along a second partial channel in the second side. In another option, the method further includes coupling with a charge port, and/or coupling with fuel storage. In still another option, the method further includes distributing fluid on two or more layers via at least a first flowpath, the first flowpath extending from a first featured layer to a second featured layer, and returning from the second featured layer to the first featured layer.
