<P>PROBLEM TO BE SOLVED: To prevent liquid junction having a simple as well as compact structure, without fail, and to secure superior power generation performance. <P>SOLUTION: A humidifier 36 is fixed directly to an end plate 62b constituting a fuel cell stack 10. A resin pipe 112 is attached to an oxidizer gas outlet 98b of the end plate 62b via a resin coupling pipe 110. The resin pipe 112 includes one end 112a at a large-diameter side and the other end 112b at a small-diameter side. The other end 112b intrudes into an off gas inflow port 40 of a humidifier joint part 101. A gap S for making a portion of the off gas circulate is provided between an outer peripheral part of the other end 112b of the resin pipe 112 and an inner wall part of the humidifier joint part 101. <P>COPYRIGHT: (C)2011,JPO&INPIT |
