Abstract

The invention relates to an enthalpy recovery fuel cell system. Water leaving the fuel cell in the cathode gas output stream is transferred to the cathode gas input stream. The dew point of the input stream of the cathode gas is about the same as the temperature of the leading edge of the active area of the solid electrolyte, such as a proton exchange membrane. The temperature differential across the fuel cell is about the same as the difference in the dew points of the cathode gas entering the fuel cell and the cathode gas exiting the fuel cell.
