Abstract
A power generation system of the present invention comprises a fuel cell system (), a gas supply device, a controller (), a combustion device (), an exhaust passage (), a gas passage used to supply a gas supplied from the gas supply device to the exhaust passage (), and a back-flow preventing device () placed in the gas passage or the exhaust passage (), and the controller () executes an operation for relieving a state in which a valve element remains incapable of moving away from a valve seat in the back-flow preventing device () in such a manner that the gas supply device is operated so that a differential pressure between an upstream side and a downstream side of the back-flow preventing device () becomes a value equal to or greater than the predetermined time which can relieve the state in which valve element remains incapable of moving away from the valve seat, during a shut-down state or at start-up of the fuel cell system ().
