  • Electrode catalyst and method of preparing electrode catalyst for fuel cell, and membrane electrode assembly and fuel cell including same
    Patent number: 9466843
    Abstract: 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 having a specific surface area of about 10 to about 30 m2/g, and a metal catalyst comprising palladium (Pd) or palladium alloy.
