ABSTRACT:
A fuel cell stack system comprises a plurality of fuel cell sub-stacks, each of which comprises a plurality of individual fuel cell units. A separator plate separates the fuel cell units between an anode of one fuel cell unit and a cathode of an adjacent fuel cell unit. A single separator plate separates corresponding fuel cell units in each fuel cell sub-stack. The edges of the separator plate extend substantially beyond the periphery of each fuel cell sub-stack forming oxidant flow paths between adjacent separator plates extending from the separator plate edges to the center of the separator plate from which oxidant is then distributed to each of the fuel cell units. By virtue of heat transfer from the extended edges of the separator plate to the oxidant, the heat generated by the fuel cell can be controlled.
