<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack with a simple and compact structure, capable of reliably preventing liquid junction, and capable of ensuring excellent power generation performance. <P>SOLUTION: A humidifier 36 is directly fixed to an end plate 62b which is a component of a fuel cell stack 10. The humidifier 36 comprises a humidifier joint 101 which is attached to the end plate 62b and has an off-gas inlet 40 which introduces off-gas into the humidifier 36, and resin-made piping 112 which is received in the humidifier joint 101 and has an off-gas introducing opening 114 which communicates with an oxidant gas outlet continuous hole 72b and an off-gas discharging opening 116 which communicates with the off-gas inlet 40. The wall of the resin-made piping 112 forming the off-gas introducing opening 114 is provided with a guide 118 which discharges the off-gas in the direction of separating from an inner wall surface 40b which forms the off-gas inlet 40. <P>COPYRIGHT: (C)2012,JPO&INPIT |
