Patent ID: 8257876

Claim:
A fuel cell system comprising: a fuel cell; a fuel supply passage through which a fuel gas supplied from a fuel supply source is supplied to the fuel cell; an on/off valve which regulates a gas flow rate and/or a gas pressure on the upstream side of the fuel supply passage to supply the gas to the downstream side thereof; and a control portion for driving and controlling the on/off valve such that a pressure of the fuel gas on the downstream side of the on/off valve becomes a target pressure, wherein the control portion is programmed to calculate a virtual drive cycle based on a fuel gas consumption in the fuel cell and a pressure of the fuel gas on the upstream side of the on/off valve, to calculate a feed-forward correction flow rate based on the virtual drive cycle, to calculate a gas injection flow rate of the on/off valve based on the feed-forward correction flow rate, and to drive and control the on/off valve based on a control signal corresponding to the gas injection flow rate.
