Zusammenfassung:The invention provides a Pt-coated MOF-801/Nafion composite membrane as well as a preparation method and application thereof, and belongs to the technical field of fuel cells. The Pt-coated MOF-801/Nafion composite membrane comprises an MOF-801/Nafion composite membrane and a platinum layer which is loaded on the surface of one side of the MOF-801/Nafion composite membrane, the loading amount of the platinum layer in the Pt-coated MOF-801/Nafion composite membrane is 0.001%-3% by weight, and the loading amount of MOF-801 in the MOF-801/Nafion composite membrane is 0.05%-30% by weight. According to the invention, MOF-801 is a metal organic framework material, has a porous characteristic, can effectively adsorb a proton carrier, provides an effective active site for proton transfer, and can form an effective path for rapid proton transfer inside, and MOF-801 has the characteristics of stability and fluorine ion resistance in an aqueous solution and acidic conditions, is an excellent porous carrier alternative m
