FUEL REFORMER

PURPOSE:To enable high efficiency of reforming reaction and contrive a small- sized and compact apparatus, by providing the first gas flow passage filled with a reforming catalyst adjacent to the second gas flow passage filled with a CO conversion catalyst. CONSTITUTION:A raw material for reforming is passed through a raw material inlet 7 and fed to a reforming catalyst layer 14. The raw material fed to the reforming catalyst layer 14 starts reforming reaction and is slowly reformed into a hydrogenenriched gas. Since the reforming reaction is endothermic reaction, heat absorption is carried out from the resultant reformed gas flowing through a CO conversion catalyst layer 15 and a combustion gas flowing through a heating layer 16. The reformed gas after completing the reforming reaction is fed to the CO conversion catalyst layer 15 to slowly carry out CO conversion reaction. The obtained gas is then led out of a reformed gas outlet 8. On the other hand, a fuel is passed through a fuel inlet 9, fed to a fuel device 12 and burned with air, passed through an air inlet 10 and fed thereto.
