<P>PROBLEM TO BE SOLVED: To properly and accurately connect a pipe for fluid of a fuel cell stack to a pipe for fluid of a humidifier by a simple structure. <P>SOLUTION: In this fuel cell system 10, the humidifier 36 is attached integrally to an end plate 62b. A pipe for fluid arranged on the end plate 62, for instance, a pipe connection part 102a of an oxidizer gas inlet manifold 98a, and a pipe for fluid constituting the humidifier 35, for instance, a pipe connection part 112a of a humidification air supply pipe 38 are connected to each other through a nearly-ring-like intermediate pipe 116. O-rings 120a and 120b are mounted to the outer peripheral part of the intermediate pipe 116 through circumferential grooves 118a and 118b, while the O-ring 120a is fitted tightly to the inside surface of the wire connection part 102a, and the O-ring 120b is fitted tightly to the inside surface of the pipe connection part 112a. <P>COPYRIGHT: (C)2008,JPO&INPIT |
