A highly active catalyst material and a high power density fuel cell using the same are provided. In a catalyst material mainly composed of a catalyst carrier mainly composed of carbon atoms 101 and a catalyst, a catalyst carrier containing a hetero atom 102 capable of coordinating with the catalyst is applied to the catalyst material. This is used for a fuel cell. Here, the heteroatom means a heteroatom in carbon. Further, including means that a hetero atom chemically bonded to a carbon atom is present in the catalyst support. However, the crystallite diameter of the carbon crystal may be large, small, or amorphous. Moreover, the hetero atom may be bonded to the hydrogen atom at the same time as being bonded to the carbon atom. [Selection] Figure 1 |
