摘要：A membrane electrode assembly comprises an anode electrode comprising ananode gas diffusion layer and an anode catalyst layer; a cathode electrode comprising a

cathode gas diffusion layer and a cathode catalyst layer; and a polymer electrolytemembrane interposed between the anode catalyst layer and the cathode catalyst layer;wherein the cathode catalyst layer comprises: a first cathode catalyst sublayer adjacentthe polymer electrolyte membrane, the first cathode catalyst sublayer comprising a firstcatalyst supported on a first carbonaceous support and a second catalyst supported on asecond carbonaceous support; and a second cathode catalyst sublayer adjacent thecathode gas diffusion layer, the second cathode catalyst sublayer comprising a thirdcatalyst supported on a third carbonaceous support; wherein the first carbonaceoussupport is carbon black and the second and third carbonaceous supports are graphitizedcarbon.
