The present invention provides a supported catalyst carrying a catalyst with a CNT-medium porous carbon composite and a CNT-medium-medium porous carbon composite as a carrier, and a fuel cell employing the supported catalyst.n n n The present invention first relates to a CNT-medium porous silica composite, and to a CNT-medium porous carbon composite prepared from the CNT-medium porous silica composite and a method for producing the CNT-medium porous carbon composite.n n n CNT-medium porous carbon composite according to the present invention, when used in the electrode of the fuel cell due to the improvement of the electrical conductivity due to the carbon nanotubes contained therein brings a remarkably superior performance compared to the conventional catalyst carrier.n n n n Nanotubes, Medium Porosity, Carbon Composites, Silica, Supported Catalysts, Fuel Cells |
