Disclosed is a fuel cell system comprising a fuel cell which is supplied with a fuel gas and an oxidizing gas and generates electricity, a fuel gas supply interrupting device for interrupting the fuel gas supply to the anode inlet of the fuel cell and an anode-off gas interrupting device for interrupting the anode-off gas discharge from the anode outlet of the fuel cell. When a problem occurs with the system, the fuel gas supply interrupting device cuts off the fuel gas supply to the anode inlet, while the anode-off gas interrupting device keeps the anode outlet open until certain conditions are fulfilled. Once the certain conditions are fulfilled, the anode-off gas interrupting device cuts off the anode-off gas discharge. |
