    摘要: A fuel cell system has a fuel cell having a cathode and an anode; a device for supplying an oxidant gas to the cathode; a device for supplying a fuel gas to the anode; a device for controlling a pressure of the oxidant gas in accordance with an operation state of the fuel cell; a regulator to which a pressure of the oxidant gas is applied as a signal pressure via a signal pressure line, wherein the regulator regulates a pressure of the fuel gas based on the signal pressure; and a device for scavenging the signal pressure line by using a scavenging gas when or after electric power generation is stopped. A device for controlling the signal pressure may be provided in the signal pressure line. Preferably, the scavenging gas has a pressure and a temperature higher than those of the oxidant gas supplied to the cathode.

    摘要: A fuel cell system enables time required for purging to be reduced without a major increase in discharge gas concentration at a time of purging. It comprises a fuel cell; a fuel gas supply path for supplying the fuel gas to an anode; an oxidizing gas supply path for supplying an oxidizing gas to a cathode; a fuel gas circulating path for returning an unreacted fuel gas to an anode inlet side; a dilution box for diluting the fuel gas by the oxidizing gas and for discharging it to outside; and a fuel gas discharge path connecting the fuel gas circulating path and a dilution box discharge gas inlet. A drain valve, a purge valve and an air discharge valve are provided, opening areas of which are different from one another. The drain valve with a smallest opening area is initially opened.
