Abstract
A method of operating a fuel cell. The method includes closing a cathode inlet valve upstream of an inlet of a cathode of the fuel cell to prevent air from entering the fuel cell through the cathode inlet during a shutdown period and a soak period of the fuel cell. The method includes maintaining an anode outlet valve downstream of an outlet of the anode in a closed state to prevent air from leaking into the fuel cell through the anode outlet during the shutdown period and the soak period of the fuel cell.
