Beschreibung
Zusammenfassung:	A control method for a fuel cell system that includes a solid oxide fuel cell configured to generate power upon receipt of supply of an anode gas and a cathode gas includes an anode protection execution determination process of performing execution determination of an anode protection process of applying a predetermined protection current to the fuel cell in order to restrain catalyst oxidation in an anode of the fuel cell. In the anode protection execution determination process, an internal impedance of the fuel cell at an anode response frequency at which an anode reaction resistance of the fuel cell is detectable is acquired, and based on the internal impedance at the anode response frequency, whether the anode protection process is to be executed or not is determined.
