Abstract: A fuel cell system (10) and method of forming the fuel cell system 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) 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 (34) to the membrane electrode assembly. A methanol concentration sensor (38) is positioned to communicate with the fuel cell membrane electrode assembly and the fuel- supply channel for regulating the mixture of fuel to the electrode assembly. An exhaust channel (38) including a water recovery and recirculation system (53) is defined in the base portion and communicating with the membrane electrode assembly.
