<P>PROBLEM TO BE SOLVED: To provide a catalyst for fuel cell, in which the surface area of metal particulates having catalyst activity can be maintained, even if it is subjected to thermal hysteresis. <P>SOLUTION: In the electrode catalyst for fuel cell, active metal particulates 3 are carried by a conductive carrier 1, and particles consisting of a third material different from the material of the carrier 1 and the material of the metal particulates 3 exist, by dispersing on the surface of the carrier, and the metal particulates 3 are carried between the particles consisting of the third material on the surface side of the carrier. <P>COPYRIGHT: (C)2010,JPO&INPIT |
