1. A fuel cell stack comprising:
a stacked body in which a plurality of power generation cells are stacked in a stacking direction, each of the power generation cells including a membrane electrode assembly and a cathode separator and an anode separator sandwiching the membrane electrode assembly, the membrane electrode assembly including an electrolyte membrane and electrodes disposed on both sides of the electrolyte membrane, wherein an oxidant gas flows over the cathode separator along an electrode surface and a fuel gas flows over the anode separator along the electrode surface; insulators that are disposed on both sides of the stacked body in the stacking direction and that have recesses in which heat-insulating members and terminal plates are accommodated; and end plates disposed outside of the insulators, wherein a first end power generation cell, which is one of the power generation cells disposed at one end of the stacked body in the stacking direction, has the cathode separator in an outermost part thereof in the stacking direction, wherein a second end power generation cell, which is one of the power generation cells disposed at the other end of the stacked body in the stacking direction, has the anode separator in an outermost part thereof in the stacking direction, and wherein the number of stacked layers included in one of the heat-insulating members adjacent to the first end power generation cell is larger than the number of stacked layers included in the other heat-insulating member adjacent to the second end power generation cell. |
