Document Type and Number:
WIPO Patent Application WO/2019/160036
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve simplicity, reduce installation space, and suppress installation costs. A fuel cell system (300) that comprises: an SOFC (313) that generates power as a result of an oxide gas being supplied to an air electrode (113) and a fuel gas being supplied to a fuel electrode (109); a plurality of exhaust fuel gas discharge lines (394) that discharge, into the atmosphere, exhaust fuel gas that has been discharged from the fuel electrode (109); exhaust fuel gas discharge valves (395, 396) that are respectively provided to the plurality of exhaust fuel gas discharge lines (394); a plurality of exhaust oxide gas discharge lines (391) that discharge, into the atmosphere, exhaust oxide gas that has been discharged from the air electrode (113); exhaust oxide gas discharge valves (392, 393) that are respectively provided to the plurality of exhaust oxide gas discharge lines (391); and a control device (380) that, when stopping the SOFC (313), closes the exhaust oxide gas discharge valves (392, 393) before the exhaust fuel gas discharge valves (395, 396).
