PURPOSE:To expand the range of choice of raw fuel gases and at the same time to prevent the lowering of an output voltage and the increase of the cost of equipment and the like by providing an ammonium removing device which removes ammonium in reformed gas to be supplied and in oxygen-containing gas. CONSTITUTION:Raw fuel gases are sucked from a raw fuel gas supply path 4 and mixed by a suction effect in an ejector 3 with steam jetted from a steam supply path 6 to supply the raw fuel gases to a reformer 7. Next, the reformed gas to which a reforming treatment is applied in the reformer 7 is supplied to an ammonium removing device 10 through a fuel gas supply path 9 to remove ammonium in the reformed gas. Also, an oxygen-containing gas side ammonium removing device 13 for removing ammonium contained in air to be supplied to an oxygen-containing gas supply part 1B is inserted in an air supply path 12. Thereby, the range of choice of raw fuel gases may be expanded, and at the same time the lowering of an output voltage and the increase of the cost of equipment as well as the running cost may be prevented. |
