<P>PROBLEM TO BE SOLVED: To provide particulate carrying carbon particle which can be used as a replacement of platinum carrying carbon particle or metal platinum particle used generally at present for an electrode catalyst of a fuel cell, capable of drastically reducing the amount of platinum used compared with conventional platinum carrying carbon particles or the like. <P>SOLUTION: A metal oxide particulate (molybdenum-noble metal-contained metal oxide particulate) which contains molybdenum and a noble metal element in a crystal lattice is carried by carbon particles. As a means of manufacturing such particulate carrying carbon particles, a method is adopted in which a solution containing complex ion of metals constituting the molybdenum-noble metal-contained metal oxide particulate is prepared firstly, then, carbon particles are dispersed in the solution obtained, and after having the complex ion of the metals adsorbed to the carbon particles, water and heat treatment is applied. <P>COPYRIGHT: (C)2007,JPO&INPIT |
