NOVELTY - A hydrogen production system comprises a carbon monoxide selective oxygenation reactor including carbon monoxide selective oxygenation catalysts containing platinum or platinum alloy and/or rhodium; and an oxidation gas providing apparatus. An outlet of a hydrogen production apparatus and oxidation gas providing apparatus are both connected to an inlet of the carbon monoxide selective oxygenation reactor. The carbon monoxide selective oxygenation catalyst further contains auxiliary agents (1-70 wt.%) from lanthanum, zirconium, copper, zinc, aluminum, and/or cerium.    USE - For producing hydrogen by methanol, useful in fuel cell device (claimed).    ADVANTAGE - The system can produce hydrogen mixture gas having carbon monoxide density lower than 50 ppm, and avoids hydrogen oxidation or explosion.    DETAILED DESCRIPTION - A hydrogen production system comprises a methanol providing apparatus; water providing apparatus; hydrogen production apparatus comprising hydrogen production catalysts; a carbon monoxide selective oxygenation reactor including carbon monoxide selective oxygenation catalysts containing platinum or platinum alloy and/or rhodium; and an oxidation gas providing apparatus. The methanol providing apparatus and water providing apparatus are connected to an inlet of hydrogen production apparatus. An outlet of the hydrogen production apparatus and oxidation gas providing apparatus are both connected to an inlet of the carbon monoxide selective oxygenation reactor. With respect to the total amount of carbon monoxide selective oxygenation catalyst, the content of platinum is 30-100 wt.% and the content of palladium and rhodium is 0-70 wt.%. The carbon monoxide selective oxygenation catalyst further contains auxiliary agents (1-70 wt.%) from lanthanum, zirconium, copper, zinc, aluminum, and/or cerium, where auxiliary agent exists in alloys of auxiliary agent and noble metal. The carbon monoxide selective oxygenation catalyst is mounted on a carrier containing substrate coating and thermal insulation regulating carrier, where substrate coating is coated on inner surface and/or outer surface of the thermal insulation regulating carrier. It is mounted on the substrate coating having a thickness of 10-30 mu m. The coating density of carbon monoxide selective oxygenation catalyst on the substrate coating is 15-35 g/m2. The thermal insulation regulating carrier is cordierite honeycomb carrier, mullite honeycomb carrier, formed alumina carrier, and/or ceramic honeycomb carrier. The substrate is from alumina, silicon oxide, unformed silicon aluminum, zirconia, titanium oxide, boron oxide, or alkaline earth metal oxides. The hydrogen production catalyst contains (wt.%): palladium (50-95) and auxiliary agent (5-50), where palladium is an alloy of palladium and auxiliary agent, which is copper, zinc, zirconium, and/or cerium. An INDEPENDENT CLAIM is included for a fuel cell device.
