| 摘要 |
An anode catalyst layer for a fuel cell is presented having first and second catalyst compositions and a hydrophobic binder. The first catalyst composition includes a noble metal, other than Ru, on a corrosion-resistant support material; the second catalyst composition contains a single-phase solid solution of a metal oxide containing Ru. The through-plane concentration of ionomer in the catalyst layer decreases as a function of distance from the membrane interface. Gas diffusion electrodes, catalyst-coated membranes, MEAs and fuel cells having the foregoing anode catalyst layer are also described. |
