<P>PROBLEM TO BE SOLVED: To provide a catalyst composed of a material inexpensive than a noble metal such as platinum, in particular as a substituting catalyst of "the catalyst mediating an electrode reaction" applied to a fuel cell, and its manufacturing method, as well as an electrode catalyst for fuel cell and a fuel cell utilizing the catalyst. <P>SOLUTION: This is a catalyst in which a carbonized molybdenum is carried on a carrier (fibrous carbon). This catalyst is manufactured through (1) a pretreatment process in which by using an oxidizer as the carrier, a reaction site for carrying the catalyst is introduced, (2) a carrying process in which a catalyst precursor is carried onto the reaction site introduced at the pretreatment process, (3) a carbonizing process in which the catalyst precursor carried in the carrying process is carbonized, and (4) an activating process in which the catalyst carbonized in the carbonizing process is activated. This catalyst can be applied to the electrode for the fuel cell or to the fuel cell. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
