Abstract
A fuel cell stack includes a stacked body, a first insulator and a second insulator. The stacked body includes power generation cells. The power generation cells are stacked in a stacking direction. The power generation cells include a first end power generation cell a second end power generation cell. Each of the power generation cells includes a membrane electrode assembly, a cathode separator and an anode separator. The first end power generation cell has an outermost cathode separator. The second end power generation cell has an outermost anode separator. The first insulator has a first recess in which a first heat-insulating body and a first terminal plate are accommodated. The second insulator has a second recess in which a second heat-insulating body and a second terminal plate are accommodated. A first number of first stacked heat-insulating layers is larger than a second number of second stacked heat-insulating layers.
