Abstract:
1. A fuel cell stack, the stack comprising: a cathode current collector; a cathode gas diffusion layer electrically coupled to the cathode current collector; a hydrophobic layer supported by the cathode gas diffusion layer; a catalyst coated proton exchange member adjacent the hydrophobic coating; a hydrophilic layer adjacent the catalyst coated proton exchange member; an anode gas diffusion layer supporting the hydrophilic layer; an anode current collector electrically coupled to the anode gas diffusion layer; a hydrogen generating fuel separated from the anode current collector by a water vapor and hydrogen permeable membrane; wherein the hydrogen generating fuel comprises a hydrogen and porous metal hydride fuel; wherein the water generated by the fuel cell exactly or substantially matches the amount of water consumed in the hydrogen generation reaction and the reaction is self-sustaining when the water generated is recycled.
