Abstract

Disclosed is an electrode catalyst comprising: (a) a support with a specific surface area of at least 1200 m/g; and (b) platinum or platinum-containing alloy particles on the support, wherein the platinum is supported on the electrode catalyst in an amount of 56˜90 wt % based on the total weight of the electrode catalyst. A membrane electrode assembly (MEA) comprising the electrode catalyst and a fuel cell using the MEA are also disclosed. The electrode catalyst comprises platinum or platinum-containing alloy particles highly dispersed on a support with a large surface area in an amount of 56 wt % or more, and thus has an extended catalytically active region, resulting in improvement in the quality of a fuel cell.
