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.

Fuel cell system, hybrid power generation system, and control method for fuel cell system

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.
