<P>PROBLEM TO BE SOLVED: To provide a highly active catalyst material and a fuel cell with high power density using the same. <P>SOLUTION: In a catalyst material that is mainly composed of a catalyst carrier having a carbon atom 101 as a main component and a catalyst, the catalyst carrier containing a hetero atom 102 that can form a coordinate bond is applied to a catalyst material which is used for a fuel cell. Here, a "hetero atom" refers to a dissimilar atom in carbon. Also, "contain" means that the hetero atom that has been chemically bonded with the carbon atom exists in the catalyst carrier. However, the crystallite size of a carbon crystal may be large or small, and besides may be amorphous. Also, the hetero atom may be bonded with the carbon atom, and at the same time may be bonded with a hydrogen atom. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
