摘要： Provided is an electrode catalyst for a fuel cell having a high activation and a high durability at the same time. The present disclosure relates to an electrode catalyst for a fuel cell including a carbon carrier and catalyst metal particles supported on the carbon carrier. The catalyst metal particles are formed of Pt or a Pt alloy. In the electrode catalyst, a BET specific surface area, a micropore area, and an R-value (= D/G) of the carbon carrier are specified. The R-value (= D/G) is an intensity ratio of a peak near 1340 cm -1 (D-band) to a peak near 1580 cm -1 (G-band) in a Raman spectroscopy analysis.
