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