    摘要： To provide a production process of an electrode catalyst for fuel cell whose initial voltage is high and whose endurance characteristics, especially, whose voltage drop being caused by high-potential application is less.
    A production process according to the present invention of an electrode catalyst for fuel cell is characterized in that : it includes: a dispersing step of dispersing a conductive support in a solution; a loading step of dropping a platinum-salt solution, a base-metal-salt solution and an iridium-salt solution to the resulting dispersion liquid, thereby loading respective metallic salts on the conductive support as hydroxides under an alkaline condition; and an alloying step of heating the conductive support with metallic hydroxides loaded in a reducing atmosphere to reduce them, thereby alloying them.

    摘要： A method for producing an electrode catalyst substrate is provided herein, which comprises a carbon film forming step of forming a porous carbon film on a base, a hydrophilization step of hydrophilizing the porous carbon film, an immersion step of immersing the base in a solution prepared by dissolving catalytic metal ions in a polar solvent, and a reduction step of adding a reducing agent to the solution and thus reducing the catalytic metal ions. An electrode catalyst substrate obtained by the method and a polymer electrolyte fuel cell in which the electrode catalyst obtained by the method is used for anodes and/or cathodes are also provided herein. In the electrode catalyst of the present invention, fine catalyst particles are loaded in a uniform and highly dispersed manner.

    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.
