Abstract: A gripping device includes a side supporting unit supporting or releasing a side of a workpiece, a plurality of pusher members pushing the workpiece downward, and a pusher member shifting unit shifting the pusher members in a direction toward or away from the workpiece. An engaging pin to be engaged with a through-hole created in the workpiece is disposed inside at least one of the pusher members.

Abstract: A fuel cell system that comprises an SOFC that generates power as a result of an oxide gas being supplied to an air electrode and a fuel gas being supplied to a fuel electrode, a plurality of exhaust fuel gas discharge lines that discharge, into the atmosphere, exhaust fuel gas that has been discharged from the fuel electrode, exhaust fuel gas discharge valves that are respectively provided to the plurality of exhaust fuel gas discharge lines, a plurality of exhaust oxide gas discharge lines that discharge, into the atmosphere, exhaust oxide gas that has been discharged from the air electrode, exhaust oxide gas discharge valves that are respectively provided to the plurality of exhaust oxide gas discharge lines, and a control device that, when stopping the SOFC, closes the exhaust oxide gas discharge valves before the exhaust fuel gas discharge valves.

Abstract: A temperature distribution control system for a fuel cell provided with a cell stack including a power generation unit that generates power by causing, in a fuel battery cell formed of a laminate of an air electrode, a solid electrolyte, and a fuel electrode, an oxidizing gas flowing on the air electrode side and a fuel gas flowing on the fuel electrode side to react with each other. The temperature distribution control system is provided with a temperature measurement unit which measures the temperature of a fuel gas supply part in the power generation unit; and a control unit which, on the basis of the result of measurement performed by the temperature measurement unit, controls the temperature of the fuel gas supply part to within an appropriate temperature range set in advance, thereby controlling a temperature distribution state in a fuel gas flow direction in the power generation unit.

Abstract: A combined power generation system is promptly activated, and stable operation thereof is provided. A control apparatus of the combined power generation system that generates power by performing cooperative operation combining an SOFC and an MGT, in which the combined power generation system includes: an exhaust fuel gas supply line that supplies exhaust fuel gas to a combustor of the MGT from the SOFC; a recirculation line that branches from the exhaust fuel gas supply line to flow the exhaust fuel gas to the SOFC; and a flow rate adjustment valve provided on a path of the exhaust fuel gas supply line, and in which a gain to an opening of the flow rate adjustment valve is adjusted according to an cooperative operation state of the SOFC and the MGT.

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.
