| 摘要 |
A membrane electrode assembly (MEA) structure includes a proton exchange membrane having opposite first and second sides, a cathode catalyst layer disposed at the first side of the proton exchange membrane, an anode catalyst layer disposed at the second side of the proton exchange membrane, a first composite gas diffusion layer disposed at the first side of the proton exchange membrane and adjacent to the cathode catalyst layer, including a first gas diffusion substrate layer and a first micro-porous layer disposed between the first gas diffusion substrate layer and the cathode catalyst layer, and a second composite gas diffusion layer disposed at the second side of the proton exchange membrane and adjacent to the anode catalyst layer, including a second gas diffusion substrate layer and a second micro-porous layer disposed between the second gas diffusion substrate layer and the anode catalyst layer.
