Provided is a fuel cell system which is capable of suppressing a state of errors remaining in the measurement by a pressure sensor. The fuel cell system includes a fuel cell, a tank storing fuel gas,a fuel gas supply flow path feeding the fuel gas from the tank to the fuel cell, a first pressure reduction unit reducing pressure of the fuel gas and feeding the fuel gas, a first pressure sensor measuring pressure in the fuel gas supply flow path, a second pressure sensor measuring pressure in the fuel gas supply flow path, a switching valve switching execution and stop of supply of the fuel gas, a correction unit correcting the first pressure sensor based on a second measurement value measured by the second pressure sensor, and a controller controlling the fuel cell system. The controller performs, when the switching valve stops supply of the fuel gas and a first measurement value is larger than a predetermined value, pressure reduction processing to make the first measurement value equal to or smaller than the
