Abstract
In a fuel cell system, a humidifier is attached to an end plate. A pipe connector of a fluid pipe provided at the end plate such as an oxygen-containing gas inlet manifold and a pipe connector of a fluid pipe of the humidifier such as a humidified air supply pipe are connected through a substantially ring-shaped intermediate pipe. O-rings are attached to annular grooves in the outer circumferential portions of the intermediate pipe. One of the O-rings tightly contacts the inner circumferential surface of the pipe connector of the oxygen-containing gas inlet manifold, and the other of the O-rings tightly contacts the inner circumferential surface of the pipe connector of the humidified air supply pipe.
