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) 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) is defined in the base portion and communicating with the membrane electrode. A multi-dimensional fuel flow field is defined in the multi-layer base portion and in communication with the fluid supply channel, the membrane electrode assembly and the exhaust channel. The membrane electrode assembly and the cooperating fluid supply channel, multi-dimensional fuel flow field, and cooperating exhaust channel forming a single fuel cell assembly.
