NOVELTY - A catalyst carrier comprises hetero atoms containing nitrogen atom which are introduced into surface of fibrous carbon. The content ratios of carbon atom and hetero atom on surface of catalyst carrier are 94:6-86:14, and content ratios of hetero atoms other than nitrogen atom with respect to nitrogen atom are 0.5-1.4.    USE - A catalyst carrier used for fuel cells (claimed).    ADVANTAGE - The catalyst carrier has high oxygen reduction catalyst activity even without using platinum.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a catalyst body comprising catalyst carrier consisting of hetero atoms containing nitrogen atom which are introduced into surface of fibrous carbon in which content ratios of carbon atom and hetero atom on surface of catalyst carrier are 94:6-86:14 and content ratios of hetero atoms other than nitrogen atom with respect to nitrogen atom are 0.5-1.4, and metal which is coordinated to introduced hetero atom;    (2) a catalyst body for fuel cell comprising catalyst body;    (3) an electrode for fuel cells comprising catalyst body for fuel cell;    (4) a fuel cell comprising electrode for fuel cells;    (5) a manufacturing method of catalyst carrier involving dispersing or dissolving fibrous carbon powder and hetero atom containing organic compound in solvent and creating liquid mixture, drying liquid mixture and obtaining catalyst-carrier precursor, and baking catalyst-carrier precursor at 650-1200 degrees C by inert atmosphere; and    (6) a manufacturing method of catalyst body involving dispersing or dissolving fibrous carbon powder and hetero atom containing organic compound in solvent and creating liquid mixture, dissolving metallic compound in liquid mixture, drying solution and obtaining catalyst precursor, and baking catalyst precursor at 650-1200 degrees C by inert atmosphere; or dispersing or dissolving fibrous carbon powder, hetero atom containing organic compound and metallic compound in solvent and creating liquid mixture, drying liquid mixture and obtaining catalyst precursor, and baking catalyst precursor at 650-1200 degrees C by inert atmosphere; or dispersing or dissolving fibrous carbon powder and hetero atom containing organic compound in solvent and creating liquid mixture, drying liquid mixture and obtaining catalyst carrier precursor, baking catalyst-carrier precursor at 650-1200 degrees C by inert atmosphere and obtaining catalyst carrier, dispersing or dissolving catalyst carrier and metallic compound in solvent, and coordinating metal to catalyst carrier.
