<P>PROBLEM TO BE SOLVED: To provide a reforming apparatus for a fuel cell with a simple constitution. <P>SOLUTION: In a reforming apparatus, for use in a fuel cell, for reforming a raw fuel into a hydrogen-rich reformed gas, a reformer 12 generates the reformed gas from the raw fuel. A shift reactor 14 reduces carbon monoxide contained in the reformed gas through a shift reaction. A selective oxidation unit 16 reduces the carbon monoxide contained in the reformed gas that has passed through the shift reactor 14 by performing selective oxidation on the carbon monoxide. A reforming reaction tube 18 houses linearly the reformer 12, the shift reactor 14 and the selective oxidation unit 16 in this order. A combustion means produces combustion exhaust gas by combusting the raw fuel. An outer casing 22 is placed around the reforming reaction tube 18, and the outer casing 22 has a larger diameter than that of the reforming reaction tube 18. A heated flow passage 32 through which the combustion exhaust gas passes to heat the reforming reaction tube 18 is formed between the reforming reaction tube 18 and the outer casing 22. <P>COPYRIGHT: (C)2009,JPO&INPIT |
