Zusammenfassung: | An electrode catalyst for a fuel cell, a membrane electrode assembly including the electrode catalyst, and a fuel cell including the electrode catalyst. The electrode catalyst has excellent electrochemical activity compared to the currently commercially available Pt/C catalyst and is much cheaper than a catalyst using platinum. The electrode catalyst includes tungsten carbide comprising amorphous carbon in the range of about 0,1 parts per weight or less based on the 100 parts by total weight of the tungsten carbide, having a specific surface area of about 10 to about 30 m 2 /g, and a metal catalyst comprising palladium (Pd) or palladium alloy. |
