MEMBRANE ELECTRODE ASSEMBLY FOR FUEL CELLS AND FABRICATION METHOD THEREOF

摘要

The invention proposes a membrane electrode assembly of a fuel cell and its fabrication method thereof. The membrane electrode assembly comprises: a proton exchange membrane; an anode layer that is disposed on a surface of the proton exchange membrane; a first cathode catalyst layer comprising at least one hydrophobic material that is disposed on the other surface of the proton exchange membrane; a second cathode catalyst layer comprising at least one hydrophilic material that is disposed on the surface of the first cathode catalyst layer; a cathode micro-porous layer that is disposed on the surface of the second cathode catalyst layer, and a cathode gas diffusion layer that is disposed on the surface of the cathode micro-porous layer.
