Abstract
One embodiment includes at least one of the anode and cathode of a fuel cell comprises a first layer and a second layer in intimate contact with each other. Both the first layer and the second layer comprise a catalyst capable of catalyzing an electrochemical reaction of a reactant gas. The second layer has a higher porosity than the first layer. A membrane electrode assembly (MEA) based on the layered electrode configuration and a process of making a fuel cell are also described.
