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.
