▎ 摘　　要

NOVELTY - Proton exchange membrane comprises base layer (1). The base layer includes exchange membrane body, first graphene layer and second graphene layer. The anode layer (2) and cathode layer (3) are respectively provided on both sides of the base layer. The anode layer includes anode film, anode diffusion layer and anode catalyst layer. The anode catalyst layer and base layer are in contact with each other. The anode film is arranged on the surface of the anode diffusion layer away from the anode catalytic layer. The cathode layer includes cathode catalyst layer, cathode diffusion layer and cathode film. The cathode catalyst layer and base layer are in contact with each other, and cathode film is arranged on the outside surface of the cathode diffusion layer. The exchange membrane body is made of combination of sulfonated polyether ether ketone solution, sulfonated polyphenylene ether, polyaniline filtrate, heteropoly acid and titanium dioxide fluid. USE - Proton exchange membrane for improving proton conductivity. ADVANTAGE - The proton exchange membrane solves the problem that the proton exchange membrane has low proton conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing proton exchange membrane for improving proton conductivity, which involves: (A) depositing graphene on surface of the metal substrate by chemical vapor deposition, dissolving sulfonated polyether ether ketone solid in N-methyl pyrrolidone to prepare sulfonated polyether ether ketone solution with mass percentage of 10%, mixing and stirring sulfonated polyether ether ketone solution, sulfonated polyphenylene ether, polyaniline filtrate and titanium dioxide fluid to obtain casting solution, placing film casting solution into tank, drying and cooling, and evaporating polar solvent in film casting solution to form primary film, soaking or boiling the primary membrane in heteropolyacid solution or water to obtain proton exchange membrane, superimposing metal matrix with graphene obtained on surface of the proton exchange membrane; and (B) transferring metal matrix with graphene to the surface of the proton exchange membrane through pressing roller. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of proton exchange membrane. Base layer (1) Anode layer (2) Cathode layer (3)
