The invention includes a proton exchange membrane fuel cell (PEMFC)
comprising at least one fuel cell assembly. The fuel cell assembly
includes a membrane electrode assembly interposed between an anode
separator and a cathode separator. The membrane electrode assembly
comprises a proton exchange membrane interposed between an anode and a
cathode, each electrode comprising an electrocatalyst. The anode and
cathode separators contain the flow field features necessary to
communicate the fuel and oxidant, respectively, to their respective
electrodes. A heat transfer separator may be integrated into the fuel
cell assembly. Each separator is made up of a series of conductive
compression gaskets that distribute fuel, oxidant and heat transfer fluid
throughout the fuel cell. Under mechanical load, the respective series of
compression gaskets are consolidated into fuel cell separators with
sufficient structural integrity to seal the PEMFC fluids.
