NOVELTY - Preparing anti-inversion capability diffusion layer comprises respectively obtaining oxide graphene nickel sub-sulfide solid, dispersant and crosslinking agent, adding oxidized graphene into solvent, mixing, adding the nickel sub-sulfide solid, mixing to obtain water electrolysis catalyst, mixing the water electrolysis catalyst, the dispersing agent and the cross-linking agent, dispersing to obtain microporous layer slurry with anti-reverse polarity ability, and spraying the microporous layer slurry on commercial gas diffusion layer to obtain gas diffusion layer with anti-inversion capability. USE - The method is useful for preparing anti-inversion capability diffusion layer used for proton exchange membrane fuel cell used in automobile field for converting hydrogen energy into electric energy. ADVANTAGE - The method improves hydrolysis reaction activity loaded on the graphene oxide, ensures the oxidation graphene the load catalyst is distributed uniformly, obtains microporous layer slurry with anti-inversion capability, and improves the anti-reverse polarity ability of the gas diffusion layer, provides gas diffusion layer with anti-inversion capability, solves the technical problem that the carbon material of the gas diffusion layers is easy to be decomposed under the condition of ensuring the catalytic performance of the catalyst in the prior art, and ensures the oxidation graphene the load catalyst is distributed uniformly. DESCRIPTION OF DRAWING(S) - The method shows a flow diagram of the method for preparing anti-inversion capability diffusion layer.
