PLATINUM AND PALLADIUM ALLOYS SUITABLE AS FUEL CELL ELECTRODES |
| 摘要 |
The present invention concerns electrode catalysts used in fuel cells, such as proton exchange membrane (PEM) fuel cells. The invention is related to the reduction of the noble metal content and the improvement of the catalytic efficiency by low level substitution of the noble metal to provide new and innovative catalyst compositions in fuel cell electrodes. The novel electrode catalysts of the invention comprise a noble metal selected from Pt and Pd alloyed with an alkaline earth metal. |

1. An electrode comprising a binary alloy containing a noble metal selected from the group consisting of Pd and Pt, and an alkaline earth metal, wherein said alloy is supported on a conductive support material, and wherein the atomic ratio between said noble metal and said alkaline earth metal is in the range 1.5:1 to 10:1. |
