Abstract
A fuel cell stack obtained by stacking a plurality of fuel cells has an internal manifold that extends in a stacking direction of the fuel cells to externally discharge a gas used in the fuel cell, and an extension member that adjoins an inner wall surface of the internal manifold and extends in the stacking direction. The extension member is a bar-shaped member provided in an opposite side to a side where a gas from the fuel cells flows to the inside of the internal manifold and has a sloping surface making an acute angle with an inner-wall lower surface of the internal manifold.
