Abstract
A fuel cell system () includes an intake pipe () that admits an introduction of oxidizing gas upstream of an oxidizing gas supply source that supplies the oxidizing gas to a fuel cell (), and an exhaust pipe () that discharges exhaust gas which contains a vapor generated at an oxygen electrode side through an operation of the fuel cell (). The fuel cell system () is provided with a circulating pipe () that connects the intake pipe and the exhaust pipe (), a circulating valve () that is provided in the circulating pipe and operated to adjust a flow rate of the exhaust gas supplied from the exhaust pipe () to the intake pipe, and a pressure generating member that is provided in the exhaust pipe () at a position at which the circulating pipe and the exhaust pipe () are joined and generates a pressure that is higher than at least an atmospheric pressure.
