摘要： The invention provides and a highly-dispersed supported catalyst that has a reduced average particle size of catalytic metal particles and is also supported by a porous support material. A method of preparing a supported catalyst that can reduce the average particle size of catalytic metal particles supported by a support material includes first mixing a charged support material with a solution containing a polymer electrolyte having a charge opposite to that of the support material to adsorb the polymer electrolyte on the support material. Next, the support material having the polymer electrolyte adsorbed thereon is mixed with a solution containing a catalytic metal precursor ion having a charge opposite to that of the polymer electrolyte to adsorb the catalytic metal precursor ion on the support material having the polymer electrolyte adsorbed on it. Finally, the catalytic metal precursor ion adsorbed on the support material having the polymer electrolyte adsorbed thereon is reduced to a catalytic metal in a reducing solution.

摘要： 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.
