REFORMING CATALYST FOR OXYGEN -CONTAINING HYDROCARBON, METHOD FOR PRODUCING HYDROGEN OR SYNTHESIS G

PROBLEM TO BE SOLVED : To provide a reforming catalyst for oxygen-containing hydrocarbon and a method for efficiently producing hydrogen or a synthesis gas using the reforming catalyst and to provide a fuel cell system using the hydrogen or the synthesis gas produced by a reforming device provided with a catalyst as a fuel. SOLUTION : In the reforming catalyst for oxygen-containing hydrocarbon, a carrier containing manganese oxide carries at least one kind of a component selected from (a) a ruthenium component, a platinum component, a rhodium component, a palladium component and an iridium component, further if necessary (b) at least one kind of a component selected from a cobalt component and/or (c) an alkali metal component, an alkaline earth metal component and a rare earth metal component. The method in which hydrogen or the synthesis gas is produced by carrying out (1) steam reforming, (2) self-heat reforming, (3) partial oxidation reforming or (4) carbon dioxide reforming of oxygen-containing hydrocarbon using the reforming catalyst, and the fuel cell system are provided.
