PROBLEM TO BE SOLVED: To provide a method for treating a combustion exhaust gas of a fuel reformer. SOLUTION: A control device 60 determines the valve opening of a flow control device 52 in accordance with the temperature of a cleaning device 40 detected via a temperature sensor 54. When the bulb opening of the flow control device 52 is determined, a flow rate of an anode off gas in proportion to the bulb opening is supplied to the cleaning device 40 via a supply pipe P5 of the anode off gas. In the cleaning device 40 containing unreacted hydrogen or unmodified fuel and the like, to which the anode off gas of a fuel cell has been supplied, the catalyst combustion of hydrogen and the like is accelerated by a catalyst 41 embedded within the cleaning device 40. The temperature of the catalyst 41 inside the cleaning device 40 is raised up to the activated temperature by the heat of reaction generated in according to the catalyst combustion of hydrogen and the like. Thus, the cleaned combustion exhaust gas is discharged from the cleaning device 40. |
