A fuel cell stack includes a stacked body, a fluid manifold, a first terminal plate, a first insulator, a first end plate, a terminal electrode, and a heat pipe assembly. The first terminal plate is provided on a first end of the stacked body in a stacking direction. The first insulator is provided on the first terminal plate in the stacking direction. The first end plate is provided on the first insulator in the stacking direction. The terminal electrode is connected to the first terminal plate and protrudes from the first end plate in the stacking direction. The heat pipe assembly includes a heat receiving portion and a heat dissipation portion. The heat receiving portion is disposed in the fluid manifold to receive heat from a fluid. The heat dissipation portion is connected to the terminal electrode to release heat received at the heat receiving portion to the terminal electrode. |

1. A fuel cell stack comprising:
a stacked body in which a plurality of power generation cells are stacked, each of the power generation cells including an electrolyte electrode assembly and a separator, the electrolyte electrode assembly including an electrolyte and a pair of electrodes sandwiching the electrolyte therebetween; a fluid manifold extending in a stacking direction of the stacked body, the fluid manifold allowing a fluid to flow therethrough, the fluid being one of a fuel gas, an oxidant gas, and a coolant; a terminal plate, an insulator, and an end plate that are disposed at each of two ends of the stacked body in the stacking direction; and a heat pipe assembly disposed in an outer portion of the fuel cell stack near at least one of the end plates, wherein the heat pipe assembly includes
a heat receiving portion disposed in the fluid manifold and receiving heat from the fluid, anda heat dissipation portion connected to a terminal electrode that is disposed on the terminal plate and that is exposed to the outside of the fuel cell stack, the heat dissipation portion dissipating heat, received by the heat receiving portion, to the terminal electrode. |
