CATHODE DESIGN FOR ELECTROCHEMICAL CELLS |
摘要 |
A membrane electrode assembly comprises an anode electrode comprising an anode gas diffusion layer and an anode catalyst layer; a cathode electrode comprising a cathode gas diffusion layer and a cathode catalyst layer; and a polymer electrolyte membrane interposed between the anode catalyst layer and the cathode catalyst layer; wherein the cathode catalyst layer comprises: a first cathode catalyst sublayer adjacent the polymer electrolyte membrane, the first cathode catalyst sublayer comprising a first catalyst supported on a first carbonaceous support and a second catalyst supported on a second carbonaceous support; and a second cathode catalyst sublayer adjacent the cathode gas diffusion layer, the second cathode catalyst sublayer comprising a third catalyst supported on a third carbonaceous support; wherein the first carbonaceous support is carbon black and the second and third carbonaceous supports are graphitized carbon. |
