FUEL CELL SYSTEM

摘要

To provide a fuel cell system capable of sensing unintended gas leakage from a discharge control means by odor. The fuel cell system includes a bypass passage (32) for joining fuel off gas passages (30) near the inlet and outlet of an odorant removal part (40) to each other. A bypass valve (33) is closed in linkage with opening of a purge valve (31) to promote the removal of odor from a fuel off gas. The bypass valve (33) is opened in linkage with stop of the discharge of the fuel off gas by closing of the purge valve (31) to suppress the removal of odor.
