Abstract

A fuel cell device (10) and method of forming the fuel cell device including a base portion (14), formed of a singular body, and having a major surface (26). At least one fuel cell membrane electrode assembly (16) including a plurality of hydrophilic threads (30) for the wicking of reaction water is formed on the major surface of the base portion. A fluid supply channel (32) including a mixing chamber (36) is defined in the base portion and communicating with the fuel cell membrane electrode assembly for supplying a fuel-bearing fluid (34) to the membrane electrode assembly. An exhaust channel (38) including a water recovery and recirculation channel (53) is defined in the base portion and communicating with the membrane electrode assembly and the plurality of hydrophilic threads. The membrane electrode assembly and the cooperating fluid supply channel and cooperating exhaust channel forming a single fuel cell assembly.
