A fuel cell system having internal pushback of water, with a compact, thermally integrated enthalpy exchanger enabling effective hydration control in a small fuel cell system is provided. The enthalpy exchanger provides for the moisture in the fuel cell effluent to be used to humidify the incoming air stream to allow the fuel cell to be operated at higher temperatures while avoiding dry out. The enthalpy exchanger includes a moisture permeable membrane which collects moisture from the exhaust flow and makes this moisture available to an incoming air stre...
What is claimed is: 1. A direct oxidation fuel cell system, comprising:(A) a protonically conductive material, having water permeability that allows a rate of internal supply of water from a cathode side to an anode side of the fuel cell to be achieved, said protonically conductive material intimately interfacing with a catalyst along each of said layer's major surfaces, and having an anode aspect and a cathode aspect;(B) a fuel source coupled to said fuel cell;(C) an enthalpy exchanger coupled to said cathode aspect having an incoming oxidant inlet cond...
