Abstract

The present invention relates to an electrode catalyst for a fuel cell that includes a carbon support (11) having pores (13) and catalyst particles containing platinum or a platinum alloy supported on the carbon support (11). The pores (13) of the carbon support (11) have a mode size of pores (13) in a range of 2.1 nm to 5.1 nm. A total pore volume of the pores (13) of the carbon support (11) is in a range of 21 cm3/g to 35 cm3/g. A distance between the catalyst particles and a surface of the carbon support (11) is in a range of 2.0 nm to 12 nm as a distance of a 50% cumulative frequency.
