In a fuel cell system (1), the output from a plurality of fuel cells (23) can reach an output greater than or equal to auxiliary driving power in a short time because the initial supply amount of raw fuel supplied from a raw fuel supply part is greater than or equal to a first supply amount that is a raw fuel supply amount corresponding to the auxiliary driving power. Thus, even if the raw fuel is supplied at the initial supply amount when a power failure has occurred in an electric power system (91) during a startup operation of the fuel cell system (1), it is possible to supply electric power from the fuel cells (23) to the auxiliary machinery (11) and continue to drive the auxiliary machinery (11) under the control of a startup controller (8). In this way, the fuel cell system (1) can immediately switch to its autonomous operation when a power failure has occurred during the startup operation. This suppresses the stop of the fuel cell system (1) under the startup operation.
