The present invention addresses the problem of providing a fuel-cell electrode catalyst in which a catalyst metal is uniformly supported on a support body. This problem can be solved by a fuel-cell electrode catalyst including a support body which has fine pores, and a catalyst metal which is uniformly supported on the support body, said fuel-cell electrode catalyst wherein at least 80% of the support body has a primary particle size within the range of ±75% of the average primary particle size of the support body. |
