SOLID POLYMER FUEL CELL CATALYST AND METHOD FOR MANUFACTURING THE SAME |
| 摘要 |
The invention is a catalyst for solid polymer fuel cell having catalyst particles composed of platinum, cobalt and magnesium supported on a carbon powder carrier, in which a composition ratio (molar ratio) among platinum, cobalt and magnesium in the catalyst particles is Pt:Co:Mg=1:0.4 to 0.5:0.00070 to 0.00095. This catalyst is manufactured by supporting cobalt and magnesium on a platinum catalyst and then conducting a heat treatment and a treatment to be brought into contact with an oxidizing solution, the feature of the catalyst manufactured in this manner includes a peak position of a main peak appearing between 2θ=40° and 42° in X-ray diffraction analysis, and the peak position is shifted to from 41.0° to 41.5°. |
