NOVELTY - The utility model claims a new proton exchange membrane fuel electrode structure, comprising a proton conductive film layer in the middle, a catalyst layer coated with heat pressing on two sides of the proton conductive film layer; a diffusion layer compounded on the outer side of the catalyst layer; the diffusion layer comprises a carbon fibre paper layer and a microporous layer coated and burned and cured on the carbon fibre paper layer; and the microporous layer material is micro powder graphite powder or graphene powder; The utility model claims a structure with uniform distribution of high hydrophobic hole structure, substantially using spherical graphite powder or micro-powder graphene to replace the original common conductive carbon black, to change the pore structure size and hydrophobic properties of the microporous layer. The graphite powder is applied to the micro-porous layer, as the main hydrophobic conductive material of the micro-porous layer, the micro-powder particle diameter size to adjust the hole structure, improving the operation stability of the battery at high altitude gas metering ratio has special meaning.
