A membrane electrode assembly for a polymer electrolyte fuel cell has a polymer electrolyte membrane, an anode, and a cathode having a catalytic layer and a diffusion layer. The alloy catalyst contains ruthenium in the anode diffusion layer. The assembly has less loss of efficiency, particularly whe...
