Abstract: 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.

Abstract: In operating the carbon monoxide removal reactor or the fuel reforming system, there is provided a technique for removing carbon monoxide in a stable manner for an extended period of time. In a method of removing carbon monoxide including an introducing step of introducing a reactant gas including mixture gas and an oxidizer added thereto to a carbon monoxide removal reactor forming in its casing a catalyst layer comprising a carbon monoxide removal catalyst for removing carbon monoxide contained in the mixture gas and an removing step of removing the carbon monoxide by causing the oxidizer to react with the mixture gas on the carbon monoxide removal catalyst, in said introducing step, the reactant gas of 100 DEG C or lower is introduced to the carbon monoxide removal reactor.
