A fuel cell system includes a fuel cell, an exhaust mechanism that is connected to a downstream end of an anode gas flow channel and is capable of selecting an exhaust mode and a closed mode, a detecting device for detecting a downstream flow of an impurity in the anode gas flow channel, and a controlling device for controlling the operation of the exhaust mechanism such that the exhaust mode is selected when the magnitude of the downstream flow of the impurity meets a predetermined switching criterion and the closed mode is selected when the magnitude of the downstream flow of the impurity does not meet the switching criterion. |
