<p>A process for preparing a hydrogen-containing gas for fuel cells, characterized by adding a gas containing an oxygen gas to a hydrogen-containing gas containing carbon monoxide prepared by the reforming reaction of an organic compound to prepare a mixed gas and bringing the mixed gas into contact with a catalyst composed mainly of a ruthenium metal and having a carbon monoxide adsorption of not less than 1 mmol/g-ruthenium and a carbon monoxide adsorption index of not less than 0.5 to thereby oxidize and remove carbon monoxide. The process can reduce the concentration of carbon monoxide in a carbon monoxide-containing hydrogen gas produced by the reforming reaction of an organic compound, thus permitting a fuel cell to be operated at a low temperature with a high efficiency.</p> |
