PROBLEM TO BE SOLVED: To provide a device for reforming fuel, which has reduced unreacted residual carbon and is capable of suppressing the production of carbon monoxide thereby being made compact in structure and has high performance. SOLUTION: The fuel reforming device 3 houses a fuel reforming catalyst for accelerating the reforming reaction of a fuel gas and produces a hydrogen enriched reformed gas by the reforming reaction of the supplied fuel gas, steam and oxygen. As for the reforming catalyst, a metal oxide material therein is controller as that its content on the side where the fuel gas is introduced is larger than that on the side where the reformed gas is discharged. Thus the partial oxidation reaction in the introducing side of the fuel gas is delayed to suppress the rapid temperature rising in this side, thereby reducing the concentration of carbon monoxide. |
