A fuel cell system installed in a vehicle includes a fuel cell that supplies power to a motor that drives the vehicle, a pump that supplies oxygen to the fuel cell, an accelerator position detector that detects an accelerator depression amount of the vehicle, and a controller that calculates required generated power of the fuel cell and required driving power of the pump, based on the accelerator depression amount. When a preset condition of causing a sharp drop in the calculated required generated power is satisfied, the controller calculates the required driving power in such a mariner that a drop rate of the required driving power becomes higher than a drop rate of the calculated required generated power, sets a lower limit to the calculated required driving power, and drives the pump in accordance with the lower limit when the required driving power is lower than the lower limit.
