FUEL CELL ELECTRODE CATALYST COMPRISING BINARY PLATINUM ALLOY AND FUEL CELL USING THE SAME |
摘要 |
An object of the present invention is to provide a fuel cell electrode catalyst which offers an improved durability while inhibiting the degradation of an initial catalytic activity to exhibit a stably high catalytic activity over a long period. The present invention provides a fuel cell electrode catalyst having an alloy carried by carbon, the alloy consisting of platinum and a platinum-family metal other tha platinum, characterized in that a composition ratio of platinum to platinum-family metal other than platinum to carbon is 1:(0.03 to 1.5):(0.46 to 2.2) (wt ratio). |
