Abstract
A fuel cell stack includes a coolant channel provided between a first separator of a first power generation cell among power generation cells and a second separator of a second power generation cell among the power generation cells which is adjacent to the first power generation cell. A coolant manifold is connected to the coolant channel. A coolant manifold end member is connected to the coolant manifold. The coolant manifold end member includes an air vent wall having an opening provided at an uppermost position of the coolant manifold end member in a height direction of the fuel cell stack. The coolant manifold end member includes a wall which surrounds the air vent wall and which is thinner than the air vent wall. The air vent pipe protrudes from the air vent wall. The air vent pipe and the coolant manifold end member are integrally made.
