    Abstract: A supported catalyst includes a carbonaceous catalyst support and first metal-second metal alloy catalyst particles adsorbed on the surface of the carbonaceous catalyst support, wherein the difference between a D10 value and a D90 value is in the range of 0.1 to 10 nm, wherein the D10 value is a mean diameter of a randomly selected 10 wt % of the first metal-second metal alloy catalyst particles and the D90 value is a mean diameter of a randomly selected 90 wt % of the alloy catalyst particles. The supported catalyst has excellent membrane efficiency in electrodes for fuel cells due to uniform alloy composition of a catalyst particle and supported catalysts that do not agglomerate.

    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.
