Fuel cell system

Abstract

A fuel cell system having an on-off valve disposed in a fuel supply flow path implements highly accurate control of the on-off valve by properly correcting a detected pressure value of a fuel gas on an upstream side of the on-off valve. The fuel cell system includes a fuel cell, a fuel supply flow path for supplying a fuel gas to be supplied from a fuel supply source to the fuel cell, an on-off valve which adjusts the state of a gas on an upstream side of the fuel supply flow path and supplies the gas to a downstream side, a pressure sensor which detects the pressure value of the fuel gas on the upstream side of the on-off valve of the fuel supply flow path, and a control means which controls the on-off valve on the basis of the pressure value detected by the pressure sensor. The fuel cell system further includes a pressure correcting means which corrects a pressure value detected by the pressure sensor on the basis of a fuel consumption amount of the fuel cell and a drive cycle of the on-off valve.
