Abstract
Provided are a supported catalyst, an electrode including the same, and a fuel cell using the electrode. The supported catalyst includes a carbon-based catalyst support and metal catalyst particles having an average diameter of 3.5 to 5 nm and an amount of 80 to 90 parts by weight based on 100 parts by weight of the supported catalyst in a multi-layer structure adsorbed on a surface of the carbon-based catalyst support. In the supported catalyst of the present invention, as small metal catalyst particles with an average diameter of 3.5 to 5 nm are dispersed with high concentration, high dispersion, and the multi-layer structure, catalytic efficiency is increased. A fuel cell having improved energy density and fuel efficiency characteristics can be prepared using an electrode formed using the supported catalyst.
