The present invention relates to a method of operating a passive, breathable fuel cell system. In one embodiment, the system of the present invention comprises at least one fuel cell and a closed fuel plenum coupled to the fuel supply. In some embodiments of the method, the fuel cell cathode is exposed to ambient air, and the fuel is supplied to the anode through the fuel plenum at a pressure greater than the pressure of the ambient air.n n n n Fuel cell system, fuel plenum, fuel supply, metal hydride |
