摘要： PROBLEM TO BE SOLVED: To provide a method of reforming a fuel by which a gas containing gaseous hydrogen mainly is produced from gaseous oxygen or air, a hydrocarbon and a steam. SOLUTION: Hydrogen is manufactured without external heating in the fuel-reforming method by making a raw material gas which contains oxygen or air, a hydrocarbon and a steam come in contact with a catalyst which simultaneously promotes an oxidation reaction of the hydrocarbon and a steam- reforming reaction of the hydrocarbon. A porous carrier of the catalyst consists of a metal oxide which contains at least Al and is loaded with precious metals such as Pd, Pt, Ru, and Rh, or the above metals and one or more metals selected from Ni, Co, Fe, Ag, Cu, Zn, Cr and rare earth elements. Exotherm of the oxidation reaction is balanced with endotherm of the steam-reforming reaction by controlling the supported quantity of the active component which promotes the oxidation reaction of the hydrocarbon and the active component which promotes the steam-reforming reaction of the hydrocarbon, as a result the whole catalyst is maintained at a prescribed temperature.

摘要： PROBLEM TO BE SOLVED: To prevent that the catalyst is overcooled at driving the catalyst, and CO contained in the reform gas outputted from the shift reaction part increases. SOLUTION: A distribution passage in which a medium 21 for cooling the catalyst is circulated is provided at the shift reaction part 2 for converting CO into CO 2 by a catalyst 2A. At driving the catalyst, the heated medium 21 circulates the catalyst 2A and heats the catalyst, and thereby, the drive operating state for making the catalyst reach the reaction temperature is made fast, and CO that is contained in the reform gas outputted from the shift reaction part 2 is reduced, and breakage due to poisoning of the electrolyte of the fuel cell can be reduced.
