Provided is a fuel cell system capable of supplying electric power to external loads without excess or deficiency even when switching between operation states is carried out. A warm-up timing judgment part judges whether or not it is time to carry out warm-up based on the temperature of a fuel cell stack. A target shift voltage determination part determines a target output voltage of the fuel cell stack used during a warm-up operation, and a voltage change speed determination part determines a voltage change speed based on electric power required from the fuel cell stack, the target output voltage of the fuel cell stack used during the warm-up operation which is output from the target shift voltage determination part and a current output voltage detected by a voltage sensor. A voltage decrease execution part carries out voltage decrease processing in accordance with the voltage change speed indicated by the voltage change speed determination part.
