An electrode catalyst for a fuel cell including a carbon-based carrier and an active metal supported in the carrier, for example, an electrode catalyst for a fuel cell includes a carrier and an active metal supported in the carrier, wherein the electrode catalyst has an X value of 95 to 100% in Equation 1. X(%)=(XPS measurement value)/(TGA measurement value)×100[Equation 1] wherein, the XPS measurement value represents a quantitative amount of the active metal present on a surface of the electrode catalyst, the TGA measurement value represents the XPS measurement value using a monochromated Al Kalpha-ray, which is the quantitative amount of total active metal supported in the catalyst. |
