A proton exchange membrane fuel cell device with an internal water management and transfer system includes a plurality of adjacently arranged proton exchange membrane assemblies including a proton exchange membrane component; a pair of porous anode and cathode catalyst layers situated on either side of the proton exchange membrane; and porous plate assemblies interposed between and in contact with each of the adjacent proton exchange membrane assemblies. Oxidant gas is supplied to oxidant gas supply channels, and fuel gas to fuel gas supply channels form...


[ What is claimed is:] [1.] A method for operating a solid polymer electrolyte membrane fuel cell power plant, said method comprising the steps of:a) providing oxidant and fuel reactant gas streams on opposite cathode and anode sides of the solid polymer electrolyte membrane;b) providing a circulating water coolant stream in communication with said cathode side and anode side of the electrolyte membrane;c) providing fine pore plates between said oxidant gas stream and said circulating water coolant stream and between said fuel gas stream and said circula...
