ABSTRACT:
A purifying system includes a purifying device for purifying a combustion-exhaust gas emitted from a fuel reforming device, a flow control valve for introducing anode-off gas discharged from a fuel cell into the purifying device through an anode-off-gas supply pipe, and a control device for controlling the opening angle of the flow control valve on the basis of the temperature of the purifying device detected by a temperature sensor, so that an oxidizing reaction of hydrogen through a catalyst incorporated in the purifying device is promoted by the introduced anode-off gas containing pre-reaction hydrogen and pre-reformed fuel. The temperature of the catalyst in the purifying device is raised by heat of the oxidizing reaction of hydrogen, to a level at which the catalyst is sufficiently activated, so that the combustion-exhaust gas is purified by the purifying device.
