A space for mutual heat exchange between the source gas and the reactant gas is installed above the reformed tube so as to reduce the temperature at the outlet of the reactant gas which is preheated and injected into the reformer and discharged after the reaction. The fuel reforming device is provided with a reforming catalyst filled therein and a fire insulating material spaced apart from a reforming tube having a burner formed thereon, and reacting with a source gas above the reforming tube 24. The mutual heat exchange space 29 of the gas is formed, and the source gas inlet 37 is formed at the upper end of the inner annular space 31 partitioned by the cylindrical separation tube 33. Is formed and a reaction gas outlet 38 is formed at the upper end of the outer annular space 32, and the reforming catalyst 36 which is filled in the inner annular space 31 can be replaced.
