<P>PROBLEM TO BE SOLVED: To provide a catalyst for an oxygen electrode in a polymer electrolyte fuel cell exhibiting a catalyst characteristic equal to that of platinum. <P>SOLUTION: This catalyst for the oxygen electrode in the polymer electrolyte fuel cell includes a metal complex having oxygen gas reduction ability. In the metal complex, an O-O bond distance, which is calculated by a B3LYP density functional method, of oxygen molecules binding to a complex center metal in an absorption structure between the metal complex and the oxygen molecule is 0.131 nm or more. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
