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 having a fuel cell using a fuel gas containing a combustible gas and an oxidant gas to generate power includes an exhaust gas route for an exhaust gas from the fuel cell to circulate, an air supplier absorbing air within the fuel cell system and supplying the air to the exhaust gas, an air supply route for the air to circulate, a merging part where the exhaust gas and the air merge, a discharge route discharging a mixed gas composed of the merged exhaust gas and the air to the atmosphere, and a combustible gas detector that detects the concentration of a combustible gas in the mixed gas. With respect to flow of the air circulating in the air supply route and the discharge route, from the upstream side, the air supplier, the merging part, and the combustible gas detector are disposed in this order.
