Abstract:
The present invention provides a catalyst which has oxygen reduction catalytic ability surpassing that of a platinum-carrying carbon material. This catalyst comprises a carbon material and a metal complex represented by formula (1).
In formula (1), X1 to X8 each independently represent a hydrogen atom or a halogen atom, D1 to D4 each represent a nitrogen atom or a carbon atom wherein the carbon atom has bound thereto a hydrogen atom or a halogen atom, and M represents a metallic atom.
