A fuel cell system includes a control unit that estimates a discharge amount of the fuel gas partially discharged from the fuel cell partially discharged during an opening period of the discharge valve based on a lost amount of the fuel gas during the opening period and a consumed amount of the fuel gas by electric generation of the fuel cell during the opening period, wherein a pressure increase period during which the pressure increases and a pressure decrease period during which the pressure decreases exist due to intermittent injection of the fuel gas, and the control unit estimates the lost amount of the fuel gas based on a decrease rate of the pressure during the pressure decrease period within the opening period, and based on an assumed decrease rate of the pressure during the pressure increase period within the opening period.
