ABSTRACT:
A fuel cell stack includes a stack body, an end separator, a terminal plate, an insulating plate, and an end plate provided at one end of the stack body in a stacking direction. The insulating plate has a recess for accommodating the terminal plate. Further, the insulating plate has a bypass passage connected between a fuel gas supply passage and a fuel gas discharge passage outside the recess for discharging condensed water. An insulating seal member is provided on the end separator to cover the bypass passage. The condensed water flows through an insulated passage formed by the insulating seal member and the bypass passage.
