In abnormality detection control, a control unit of the fuel cell system obtains a maximum filling pressure that is a maximum value of the pressure in a filling flow path during filling, and determines that both of first and second pressure sensors are normal when the difference between a supply start pressure and the maximum filling pressure is equal to or smaller than a reference value. When this difference is larger than the reference value, the control unit determines that there is a possibility that at least one of the first and second pressure sensors may be abnormal. The supply start pressure is a detection value of the second pressure sensor at the time when supply of fuel gas to a fuel cell is started for the first time after filling of a fuel tank with the fuel gas is finished.
