    摘要： To enhance the activation of a catalyst comprising an alloy of platinum and cobalt, thereby providing an electrode catalyst for fuel cell whose battery output and fuel efficiency are high, and thereby providing a production process of the same.An electrode catalyst according to the present invention for fuel cell is an electrode catalyst for fuel cell in which catalytic particles comprising platinum and cobalt are loaded on a conductive support, and is characterized in that a compositional (molar) ratio of said catalytic particles is platinum:cobalt=3:1-5:1: In the range of platinum:cobalt=3:1-5:1, a high battery voltage is obtainable. When the proportion of platinum is less than platinum: cobalt=3:1, the elution of cobalt from out of catalyst increases. On the contrarily, when the proportion of platinum is more than platinum: cobalt=5:1, the catalytic activities become low.
