Abstract
The present invention utilizes an electrochemical catalyst which contains: a metal oxide that is composed of one or more compounds selected from among zirconium oxide, cerium oxide, yttrium oxide, gadolinium oxide, samarium oxide, cobalt oxide and scandium oxide; and a metal variant, which has a valence that is different from the valence of the metal that constitutes the metal oxide.
