There is disclosed a fuel cell system or the like capable of stably operating an auxiliary machine and the like, even when recovering a poisoned electrode catalyst and warming up a fuel cell. A controller derives a target operation point sufficient for recovering activity of the poisoned electrode catalyst, and realizes shift of an operation point to a target operation point in a state in which an output power is held to be constant. The operation is switched to a low-efficiency operation point, whereby an output voltage of the fuel cell lowers, but the voltage is raised to an allowable input voltage of a high-voltage auxiliary machine by a DC/DC converter.
