Abstract
The system includes an exhaust fuel gas line, an exhaust-fuel-gas supplying line, a recirculating line that circulates the exhaust fuel gas to the SOFC, a shut-off valve in a vent line that splits off on the upstream side of the branching point, an orifice on the downstream side of the shut-off valve, a water supplying portion that supplies water to the recirculating line, and a DPX that measures the system pressure difference of the SOFC, and, when stopping power generation by the SOFC or when power generation by the SOFC comes to an abnormal stop, the shut-off valve is opened, while causing a predetermined amount of pressure loss in the vent line by using the orifice, and thus, the water flow volume of the water supplying portion is controlled so that the pressure difference measured by the DPX reaches a predetermined value.
