ELECTRODE CATALYST FOR FUEL CELL, AND FUEL CELL USING SAME

An objective of the present invention is to provide: an electrode catalyst for a fuel cell, the electrode catalyst having high initial activity and being capable of long-term retention of said activity; and a fuel cell using the electrode catalyst for a fuel cell. The present invention pertains to: an electrode catalyst for a fuel cell, the electrode catalyst comprising catalyst metal particles that include platinum or a platinum alloy, and carrier particles that carry said catalyst metal particles, wherein the carrier particles are a carbonaceous material having a cumulative pore volume of 0.10cc/g or less in the diameter range of 2nm or less, and a BET specific surface area of greater than 900m/g; and a fuel cell comprising the electrode catalyst for a fuel cell.
