example 1
[0028] MEA was prepared by using carbon material loaded with 40wt% Pt-Ru alloy as anode catalyst, carbon material loaded with 20% wt% Pb as cathode catalyst, Nafion membrane as proton exchange membrane, and carbon paper impregnated with PTFE as catalyst layer . The present invention has no special limitation on the polytetrafluoroethylene impregnation treatment method, as long as the technical solution of polytetrafluoroethylene impregnation treatment well known to those skilled in the art is adopted.
[0029] The Pt-Ru alloy-supported carbon material and the single metal-supported carbon material can be purchased directly, or can be prepared by oneself. The present invention has no special restrictions on the preparation method of the carbon material, and the technical scheme of loading metal on the supporting carbon well known to those skilled in the art may be adopted.
