ELECTROCHEMICAL ELEMENT, ELECTROCHEMICAL DEVICE, METHOD OF RESTRAINING POISONING OF PROTON-GENERATING CATALYST AND COMPLEX CATALYST

Document Type and Number:

Japanese Patent JP2003272660

Kind Code:

A

Abstract:

To restrain poisoning of a proton-generating catalyst and enable to maintain a given operating condition in an electrochemical element.

The electrochemical element generates a solid proton conductor 6 and proton, supplies the solid proton conductor 6 with proton, and is provided with a proton-generating catalyst prone to receive poisoning by carbon monoxide. The element is further provided with a photocatalyst for oxidizing carbon monoxide at irradiation.
