Abstract: A fuel cell system includes: a fuel cell; a fuel gas path supplied with fuel and allowing a part of fuel gas discharged from the fuel cell to circulate; an exhaust mechanism discharging the reacted fuel gas to an outside; a circulation mechanism circulating the fuel gas; and a control unit configured to temporarily stop circulation of the fuel gas by the circulation mechanism when determining that discharge from the exhaust mechanism is not normal, drive the circulation mechanism so that the fuel gas circulates at a first circulation speed when determining that the discharge is not normal and a parameter relating to water vapor in the fuel gas path is equal to a predetermined value or greater, and drive the circulation mechanism so that the fuel gas circulates at a second circulation speed greater than the first circulation speed when determining that the discharge is normal.

Abstract: A method includes predicting, while fuel cell system is operated, whether or not the outside temperature becomes equal to or less than a first predetermined temperature; performing, when it is predicted that the outside temperature becomes equal to or less than the first predetermined temperature, residual water scavenging processing on only an oxidizer gas supply/discharge mechanism and thereafter stopping the operation of the fuel cell system; predicting, after the stop of the operation of the fuel cell system, whether or not the temperature of a predetermined component included in the fuel cell system becomes equal to or less than a second predetermined temperature; and performing the residual water scavenging processing on the fuel gas supply/discharge mechanism when it is predicted that the temperature of the predetermined component becomes equal to or less than the second predetermined temperature.
