ABSTRACT:
A supported catalyst for a fuel cell, a method of preparing the same, an electrode for a fuel cell including the supported catalyst, and a fuel cell including the electrode. The supported catalyst for the fuel cell includes a graphite based catalyst carrier; a first catalyst metal particle adsorbed on the surface of the graphite based catalyst carrier, wherein the amount of the first catalyst metal particle is at least 30 wt % based on the supported catalyst; and a second catalyst metal particle impregnated on the surface of the first catalyst metal particle. The supported catalyst for a fuel cell uses a graphite based catalyst carrier to increase durability of the fuel cell. Accordingly, the supported catalyst for the fuel cell provides superior energy density and fuel efficiency, by minimizing the loss of a metal catalyst impregnated in the graphite based catalyst carrier and regulating the amount of the impregnated metal catalyst.
