Abstract: A device includes a case having a surface with a perforation and a cavity. A membrane is supported by the case inside the cavity and has an impermeable valve plate positioned proximate the perforation. The membrane is water vapor permeable and gas impermeable and flexes responsive to a difference in pressure between the cavity and outside the cavity to selectively allow water vapor to pass through the perforation into the cavity as a function of the difference in pressure.

Abstract: A power generator includes a chemical hydride multilayer fuel cell stack. A flow path extends through the fuel cell stack to provide oxygen containing air to the fuel cell stack and to cool the fuel cell stack. A hydrogen generator is coupled to the flow path to receive water vapor from ambient air introduced into the flow path and water vapor generated by the fuel cell stack and to provide hydrogen to the fuel cell stack. A controller separately controls airflow past the fuel cell stack and water vapor provided to the hydrogen generator.

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.
