The present invention relates to a fuel cell system. More specifically, the purpose of the present invention is to provide a fuel cell system in which reduction in estimated accuracy in displacement of fuel gas is prevented in a wide load region of the fuel cell. A controlling part of the fuel cell system estimates the displacement of the fuel gas based on the loss in fuel gas calculated from pressure reduction rate if the load current value falls below a standard value and also the fuel cell consumption by the generation of the fuel cell calculated from the load current value. If the load current value exceeds the standard value, estimation is made on the exhausted amount of the fuel cell based on the differential pressure. |
