Title:
FUEL CELL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/091127
Kind Code:
A1
Abstract:
The purpose is to prevent the backward flow of exhaust gas with a cathode air power increase process, in the case that a current direction detection unit (23) detects that exhaust gas flowing toward an exhaust opening (26) is flowing backward in an exhaust system for discharging combustion gas of off gas emitted from a power generation unit (21) in this fuel cell system (1). Hence, with this fuel cell system (1) it is possible to prevent life-shortening, caused by the backward flow of exhaust gas to the power generation unit (21) side, for a fuel cell stack (5), various catalysts, absorbing agents, ion-exchange resins, various auxiliaries, or the like.
