Abstract
A fuel cell system includes a fuel cell; a circulating system that circulates and supplies fuel off-gas discharged from the fuel cell to the fuel cell; a pump that pumps a fluid in the circulating system; a discharge valve through which the fluid in the circulating system is discharged to the outside; and a control device that controls the pump and the discharge valve. If operation of the fuel cell is started in a cold environment, the control device executes a control to start power generation in the fuel cell for a first period before activating the pump and executes a control to drive the pump while the discharge valve is closed for a second period.
