Abstract: A fuel cell system includes a fuel cell, a first supply flow path, a second supply flow path, a recycle flow path, a circulator, a discharge flow path, a reservoir, a valve, and a controller. The controller opens the valve, determines an open time, for which the valve is opened to discharge the anode off gas, on the basis of the amount of water stored in the reservoir, the discharge time of water that flows through the discharge flow path to be discharged, and the discharge amount of the anode off gas that flows through the discharge flow path to be discharged, and closes the valve when an elapsed time for which the valve is opened reaches the open time.

Abstract: A fuel cell system includes: a fuel cell including an anode gas flow channel and a cathode gas flow channel and generating electricity from a hydrogen-containing anode gas of the anode gas flow channel and an oxygen-containing cathode gas of the cathode gas flow channel; an anode off-gas emission path through which an anode off-gas emitted from the anode gas flow channel flows; and a cathode off-gas emission path through which a cathode off-gas emitted from the cathode gas flow channel flows. After stoppage of generation of electricity by the fuel cell, gas purging is performed in which at least a part of the cathode off-gas emission path is purged with a hydrogen-containing gas having passed through a junction where the anode off-gas emission path and the cathode off-gas emission path meet each other. The hydrogen-containing gas contains at least either the anode gas or the anode off-gas.
