CATALYST FOR REMOVING CARBON MONOXIDE AND METHOD OF REMOVING CARBON MONOXIDE

摘要

A carbon monoxide removing catalyst such as a ruthenium supporting catalyst is provided for removing, through oxidation thereof, carbon monoxide from an alcohol reformed gas containing hydrogen and carbon monoxide to be supplied to a fuel cell. For its activation, the catalyst is caused to contact an inactive gas or a hydrogen-containing inactive gas consisting of less than 50 volume % of hydrogen gas and the remaining volume of inactive gas, thereby to avoid poisoning of the electrode of the fuel cell with carbon monoxide.
