摘要： A fuel cell system includes a fuel cell, a circulation path, a water reservoir, a water level detector, a water discharger and a controller. The fuel cell generates electric power using fuel gas supplied to an anode and oxidant gas supplied to a cathode. Off-gas discharged from the fuel cell is returned to the fuel cell again through the circulation path. The water reservoir is disposed in the circulation path and stores water separated from the off-gas. During monitoring after stop of the fuel cell system or at startup of the fuel cell system, the controller operates the water discharger to discharge the water stored in the water reservoir when the controller determines that a level of the water detected or estimated by the water level detector is equal to or higher than a predetermined reference water level.
