Claim 0:
1. A membrane electrode assembly with high-efficiency water and heat management for a direct ethanol fuel cell (DEFC), comprising an anode, a cathode, and a proton-exchange membrane,
wherein the anode is composed of an anode diffusion layer and an anode catalyst layer, and the cathode is composed of a cathode diffusion layer and a cathode catalyst layer,
the cathode catalyst layer is of a convex and ordered design with a convex curvature radius R1 of 0.2 mm to 0.3 mm and a convex angle θ of 40° to 60°, and
the anode catalyst layer is of a concave and ordered design with a concave curvature radius R2 of 0.2 mm to 0.3 mm and a concave angle α of 30° to 45°.
