A fuel cell stack that can suppress degraded cooling performance due to the presence of air bubbles. The fuel cell stack includes a plurality of stacked fuel cells, each fuel cell having a power generation portion and a pair of separators. The fuel cell stack further includes a plurality of refrigerant channels inside the power generation portion that are provided in a region corresponding to the power generation portion and that allow communication between the refrigerant inlet manifold and refrigerant outlet manifold, and a refrigerant channel outside the power generation portion that is provided in a region above the power generation portion in the gravity direction and that allows communication between the refrigerant inlet manifold and refrigerant outlet manifold. The refrigerant channels inside and outside the power generation portion communicate with each other.
