This catalyst has a high selective oxidation activity to carbon monoxide. A carbon monoxide elimination method using this catalyst is also provided. In this method, to a gas containing at least hydrogen and carbon monoxide and being richer in the hydrogen than the carbon monoxide on the basis of volume, oxygen is added in an amount necessary for oxidizing at least part of carbon monoxide present in that gas, and thereafter the gas to which the oxygen has been added is brought into contact with the catalyst described above. Also provided is a solid polymer electrolyte fuel cell system that utilizes this method.

摘要： A catalyst for selectively oxidizing carbon monoxide in a hydrogen-containing gas comprises an alumina hydrate carrier and at least platinum supported thereon. With an aluminum hydrate as a carrier, the catalyst is resistant to deactivation which would be caused by an oxygen-containing hydrocarbon in a hydrogen-rich gas. The method for selectively removing carbon monoxide comprises the steps of adding oxygen to a hydrogen-rich gas containing carbon monoxide, in an amount necessary to oxidize at least part of carbon monoxide, and bringing the resulting mixture into contact with the catalyst for selectively oxidizing carbon monoxide. The solid polymer electrolyte-type fuel cell system utilizes the above method for selectively removing carbon monoxide.

摘要： In a reforming catalyst apparatus provided with a reforming catalyst for forming a hydrogen rich reformed gas by a reforming reaction of the fuel with water, the catalyst performance can be recovered by heating the catalyst within a temperature ranging from 500° C. to 800° C. while supplying said fuel and air to the catalyst. This method allows recovery of the catalyst performance without demounting the catalyst from the reforming catalyst apparatus and allows providing the reforming catalyst with a long service life.

摘要： A fuel supplying apparatus for maintaining a stable supply of a mixed water-methanol solution while preventing water from freezing in a cold climate, and for immediately supplying a mixed water-methanol gas that has a composition which is outside of the high-rate reaction region during the starting/stopping operation of the reformer when the control tends to be unstable. The methanol reforming apparatus that generates a hydrogen-rich gas by reacting a mixed gas of water, methanol and air on a catalyst is supplied with the fuel from a fuel supplying apparatus comprising a mixed water-methanol solution tank wherein the molar ratio of water and methanol used for reforming is controlled to a predetermined value, a mixed water-methanol solution tank wherein the molar ratio of water and methanol is controlled to 4.6 or higher, and a switching means that switches the mixed water-methanol solution tank used as a fuel source according to the conditions of operation of the methanol reforming apparatus.
