ABSTRACT:
A power generator comprising a hydrogen generator and a fuel cell stack having an anode exposed to hydrogen from the hydrogen generator and a cathode exposed to an ambient environment. Hydrophobic and hydrophilic layers are used to promote flow of water away from the cathode. A diffusion path thus separates the fuel cell cathode from the hydrogen generator. In one embodiment, water vapor generated from the fuel cell substantially matches water used by the hydrogen generator to generate hydrogen.
