ABSTRACT:
A fuel cell including a membrane electrode assembly composed of a ionically conductive member sandwiched between a pair of electrodes. At least one of the electrodes including a catalyst loading characterized by catalytic activity that varies in proportion to the catalyst loading. Moreover, the fuel cell includes a flow path for supplying gaseous reactants to the electrodes and the catalyst loading is varied according to the flow path geometry.
