Claim Text:
1. A fuel cell stack, comprising: unit cells that are stacked together and form a manifold; a first end plate that is disposed at an outermost end of the unit cells, the first end plate being an open end plate in which a reaction gas inlet and outlet that is connected to the manifold of the first end plate are formed; a second end plate that is disposed at an opposing outermost end of the unit cells, the second end plate being a closed end plate that closes the manifold; and a reaction gas that flows into the reaction gas inlet through a first slanted surface of the first end plate, wherein the first slanted surface widens the manifold from the first end plate toward an interior of the stacked unit cells to adjust a flow of the reaction gas at a manifold interface of the first end plate and to minimize distribution deviation, wherein the first and second end plate press against the unit cells.
