Abstract
A fuel cell electrode catalyst includes: a noble-metal-supported catalyst including a carbon support and a noble metal supported on the carbon support; and a water-repellent material with which the noble-metal-supported catalyst is modified. The carbon support is mesoporous carbon in which a pore volume of pores having a pore size of 2 nm to 5 nm is 2.1 ml/g to 2.4 ml/g. An amount of the water-repellent material is 3% by weight to 7% by weight with respect to a total weight of the mesoporous carbon and the water-repellent material.
