Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 61/993,525 filed on May 15, 2014. The above identified patent application is herein incorporated by reference in its entirety to provide continuity of disclosure.

FIELD OF THE INVENTION

The present invention relates to a method of producing hydrogen gas, and more particularly to a method of producing hydrogen gas from distilled water or sea water using an electrolytic process to provide an alternative fuel source for automobiles and all other industries where solid, liquid, gas and nuclear material are used as a fuel.

BACKGROUND OF THE INVENTION

As the cost of fossil fuels increase and become more scarce due to continuous demand, there is an increasing need to develop alternative fuel sources. The alternative fuel sources must be cheap and commercially available before the world's supply of fossil fuels are completely depleted or become too expensive. Additionally, burning fossil fuels contributes to a substantial portion of the world's pollution, resulting in a negative effect on the environment. Therefore, there is also a need for an alternative fuel source that is clean burning and does not pollute to the degree of fossil fuels.
For that reason, a process for extracting hydrogen gas from water is an important technology to replace fossil fuels and may become increasingly critical as an alternative energy source. Various methods of producing hydrogen gas utilizing sulfuric acid, water, and electrolysis have been disclosed in the prior art. Particularly, electrolysis of water for the production of hydrogen and oxygen is a common method for producing hydrogen. By providing energy from a battery, water (H₂O) can be dissociated into the diatomic molecules of hydrogen (H₂) and oxygen (O₂). In electrolysis, a direct current is passed through an aqueous electrolyte, usually a solution of caustic soda or caustic potash. Hydrogen is deposited at the cathode or negative electrode and oxygen at the anode or positive electrode.
Unfortunately, commercial applications of water electrolysis are inefficient and energy-intensive processes. Pure water is a good insulator and under simple or normal electrolysis conditions, pure water creates little dissociated products. Current technologies attempt to address these issues by adding a water-soluble electrolyte, which causes the conductivity of the water to rise considerably. The electrolyte disassociates into cations and anions; the anions move towards the anode and neutralize the buildup of positively charged H+ ions and the cations move towards the cathode and neutralize the buildup of negatively charged OH- ions. This allows the continued flow of electricity. However, there are numerous problems associated with electrolytes within the reaction cell. Specifically, an electrolyte anion with less standard electrode potential than hydroxide will be oxidized instead of the hydroxide, and no oxygen gas will be produced; where as a cation with a greater standard electrode potential than a hydrogen ion will be reduced instead and no hydrogen gas will be produced. In all water electrolysis cases where electrolytes are used, the gaseous product effluents are extremely corrosive and create numerous application problems.
Therefore, there is a need for a process that efficiently dissociates water into hydrogen gas and oxygen gas, which is reproducible as an alternate fuel source.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of methods of producing hydrogen gas now present in the prior art, the present invention provides an improved method for producing hydrogen gas wherein the hydrogen gas can be utilized as an alternative fuel source.

The figures are intended for representative purposes only and should not be considered to be limiting in any respect.
Referring now to FIG. 1, there is shown a schematic diagram of the housing which is used to produce the hydrogen gas according to one embodiment of the present invention.

The gas chamber 104 further comprise a separations unit 122 to extract pure hydrogen gas from the mixture in the gas chamber 104. The separations unit 122 seperates the hydrogen from the gas mixture via steam reformation. Oxygen gas is also generated as a byproduct of the electrolytic process and may also rise to the gas chamber 104.
The housing 102 may further include an electrolytic solution 108 in the electrolyte chamber 106 of the housing 102. The electrolyte solution 108 may comprise distilled water and an electrolyte. It is also contemplated that sea water can be used, however, distilled water enhances the process and life of the electrodes. The electrolyte added to the distilled water may include, but is not limited to, sodium hydroxide, sodium chloride, brine, potassium hydroxide, copper sulfate, sulfuric acid and other acids and bases. It is preferable that that electrolyte added to the distilled water is either copper sulfate or sulfuric acid.
A circuit 110 may be disposed in the electrolyte chamber 106 of the housing 102. The circuit 110 may include a cathode 112, an anode 114, and an electrical connection 116. The electrical connection 116 connects the cathode 112 and the anode 114, forming the circuit 110. Electricity flows from the cathode 112 to the anode 114, whereby the distilled water in the electrolyte solution is dissociated to produce hydrogen gas at the cathode and oxygen gas at the anode.

An electrical potential flows between the first electrode and second electrode whereby the distilled water in the electrolyte is dissociated to produce hydrogen gas at the first electrode and oxygen gas at the second electrode. It is preferable that the first electrode is a cathode and the second electrode is an anode. When the water disassociates, hydrogen gas is collected from the cathode and oxygen gas is collected from the anode. The hydrogen gas produced at the cathode may be collected in the gas chamber of the housing and the oxygen produced at the anode may be purged from the housing, and released into the atmosphere. The circuit may include a plurality of cathodes and a plurality of anodes arranged in a series.

Further, the method may include exhausting 314 the gas produced at the second electrolyte from the electrolyte chamber. The method may further include continuously circulating 316 fresh copper sulfate or sulfuric acid to the electrolyte chamber.
Referring now to FIG. 4, there is shown a method 400 of producing hydrogen gas from distilled water including the steps of providing 402 a housing comprising a first gas chamber, a second gas chamber and an electrolyte chamber. The first gas chamber collects hydrogen gas and the second gas chamber collects oxygen. After step 402, the method includes adding 404 a predetermined volume of distilled water to the electrolyte chamber of the housing.
After step 404, the method includes adding 406 an electrolyte to the distilled water contained in the electrolyte chamber. The mixture of the distilled water and the electrolyte forms an electrolytic solution. The electrolyte added to the distilled water may be selected from a group consisting of copper sulfate and sulfuric acid.
After step 406, the method further includes providing 408 a circuit within the electrolyte chamber.

After step 410, the method further includes maintaining 412 the hydrogen gas generated at the cathode at a sufficient pressure to prevent the hydrogen gas from diffusing back into the electrolytic solution. The pressure is maintained by providing a pressurized container that is pressurized above the hydrogen gas disassociation constant. After step 412, the method further includes collecting 414 the hydrogen gas in the first gas chamber of the housing and collecting 416 the oxygen gas produced in a second gas chamber.
