Abstract
A fuel cell system of the present invention comprises a fuel cell which is supplied with a fuel gas and an oxidizing gas to generate electricity, a fuel gas supply interrupting device for interrupting the fuel gas supply to an anode inlet of the fuel cell, and an anode-off gas interrupting device for interrupting the discharge of anode-off gas from an anode outlet of the fuel cell. When a problem occurs in 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 opens the anode outlet when the problem in the system occurs, and cuts off the anode-off gas once a predetermined condition has been satisfied.
