Abstract
This invention provides an electrode catalyst having excellent catalytic performance that, even when a large amount of noble metal particles are supported on a carrier, can surely provide a fuel cell having high power generation performance. The electrode catalyst for a fuel cell comprises a noble metal as a catalyst component supported on an electrically conductive carrier and is characterized in that the amount of the noble metal supported based on the total of the electrically conductive carrier and the noble metal is 70 to 90% by mass, the apparent surface area (S1) of the noble metal supported is 25 to 60 m2/g, and the ratio between the apparent surface area (S1) of the noble metal supported and the apparent surface area (S2) of the electrically conductive carrier, i.e., S1/S2, is 0.02/1 to 0.1/1.
