    Abstract: PROBLEM TO BE SOLVED: To provide a high concentration carbon supported catalyst in which the catalytic metal particles have a very small size and a high degree of dispersion despite a high loading of the supported catalyst.
    SOLUTION: The high concentration carbon supported catalyst has Pt or a Pt alloy supported in an electrically conductive carbon support, wherein the concentration of the supported Pt or Pt alloy is in the range of 50% to 60% by weight, an average particle size is 1 to 5 nm, and a total specific surface area of the carbon supported catalyst is 200 m
    2 /g or greater. Such a catalyst can be prepared by a method comprising: at least two-time impregnations of the carbon support with a solvent and a precursor of a catalytic metal to be finally supported; and drying and reducing the carbon support impregnated with the precursor of the catalytic metal, to be performed between the impregnations.
