▎ 摘　　要

NOVELTY - The structure comprises an anode gas diffusion layer (1), an anode catalytic layer (2), a proton exchange layer (3), a cathode catalytic layer (4) and a cathode gas diffusion layer (5) arranged in turn, where the anode transition layer is arranged between the anode gas diffusion layer and the anode catalyst layer, the anode transition layer comprises a sacrificial anode graphite layer (6) set on the surface of the anode catalytic layer, and oxygen evolution reaction catalytic layer (7) set between the sacrificial anode graphite layer and the anode gas diffusion layer. The sacrificial anode graphite layer is a mixture of graphitized carbon powder and Nafion (Sulfonated tetrafluoroethylene based fluoropolymer-copolymer) solution. The oxygen evolution reaction catalytic layer is a mixture of electrolytic water catalyst, oxidation resistant catalyst carrier and Nafion (Sulfonated tetrafluoroethylene based fluoropolymer-copolymer)solution. USE - Anti-inversion optimization design membrane electrode assembly structure for proton exchange membrane fuel cell (PEMFC), and also used in petroleum, coal, natural gas and nuclear energy. ADVANTAGE - The anti-inversion optimization design membrane electrode assembly structure prevents the corrosion of the fuel cell assembly, and prolongs the service life. The fuel cell anti-reverse polarity capability is greatly improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for optimization method of membrane electrode assembly anti-reverse performance, used for the membrane electrode assembly. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the anti-inversion optimization design membrane electrode assembly structure.
