An efficient method for producing a hydrogen-containing gas for a fuel cell by using a gas produced by reforming reaction of an organic compound is disclosed. The method comprises the following steps: adding an oxygen-containing gas to a hydrogen-containing gas containing carbon monoxide to form a mixed gas, and bringing the mixed gas into contact with a catalyst comprising a ruthenium metal as a main component 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.
