Fuel cell stack

摘要

A fuel cell stack includes a stacked body, insulators, end plates, heat insulating members, and terminal plates. In the stacked body, a plurality of power generation cells are stacked in a stacking direction. Each of the plurality of power generation cells includes a separator and an electrolyte electrode assembly which includes an electrolyte and a pair of electrodes sandwiching the electrolyte therebetween. The stacked body has a first end portion and a second end portion opposite to the first end portion in the stacking direction. The insulators are provided at the first end portion and the second end portion of the stacked body, respectively. Each of the insulators has a recessed portion that faces toward the stacked body. The end plates are provided on the insulators, respectively. The heat insulating members are each provided in the recessed portion. The terminal plates are each provided in the recessed portion.
