    摘要： A membrane electrode assembly of a fuel cell comprises a proton exchange membrane, two metal-carbon (carbon supported metal) catalyst layers, two gas diffusion layers and at least two metal catalyst layers. The proton exchange membrane is at the center of the membrane electrode assembly, the two metal-carbon catalyst layers are located on both sides of the proton exchange membrane. The two gas diffusion layers are on both outer surfaces of the membrane electrode assembly. The metal catalyst layers are located at the interface between the proton exchanged membrane and the metal-carbon catalyst layer and/or at the interface between the metal-carbon catalyst layer and the gas diffusion layer. The combinations of metal-carbon catalyst and metal-catalyst layers reduce the thickness of catalyst layer and maintain a high catalysis activity, and thus improve the fuel cells performance.
