ABSTRACT:
An electrode for a fuel cell, including a porous catalytic carrier including conductive fibers having two particle diameter distribution peaks of a first particle diameter distribution peak existing at a small particle diameter side and a second particle diameter distribution peak existing at a large particle diameter side, wherein said conducting fibers are carbon nano-fibers formed from a catalyst for formation prepared by preparing a mixed powder including one or more of a reducible metallic oxide powder and a non-reducible metallic oxide powder, mixing and pulverizing the mixed powder, and heating the mixed powder under reducing atmosphere; catalyst to be carried on said conductive fibers belonging to the first particle diameter distribution peak; and a proton conductive material adhered on surface of at least the conducive fibers belonging to the first particle diameter distribution peak, so as to come into contact with the catalyst.
