Abstract
A fuel cell systemincludes a fuel cell, a cathode gas supply system, a supply valve, an exhaust valveand a controller. The fuel cellhas a supply manifold M, an exhaust manifold M, and a power generation area GA connected with these manifolds Mand M. The cathode gas supply systemcauses a gas to be flowed into the supply manifold M. The supply valveis operable to seal the supply manifold M, whereas the exhaust valveis operable to seal the exhaust manifold M. The controllercloses the supply valveand the exhaust valveafter operation stop of the fuel cellto seal the fuel cellunder a specified pressure and then waits for a predefined time. The controllersubsequently opens the supply valveto move water remaining in the power generation area GA on the flow of the gas toward outside of the power generation area GA.
