PURPOSE:To obtain a long lifetime of catalyst-activity by containing an alloy of platinum, nickle and chromium within a catalyst for an electrode. CONSTITUTION:A catalyst contains an alloy of platinum, nickel and chromium. Accordingly this catalyst suppresses any decrease in the surface area of platinum caused by gradual coherence of particulate platinum in use. Therefore, an electromotive force is rarely reduced and a initial activity as an oxygen reducing catalyst can also be improved. |
