    Abstract: A fuel cell stack is provided that includes unit cells that include a manifold, an open end plate that is disposed at one side of the unit cells and that has a reaction gas inlet and outlet that are connected to the manifold, and a closed end plate that is disposed at the other side of the unit cells and that closes the manifold. In particular, the open end plate includes a first slanted surface that adjusts a flow of a reaction gas at a reaction gas inlet and a manifold interface. A first alignment protrusion forms the first slanted surface and that aligns the unit cells, and the closed end plate includes a second slanted surface that adjusts flow of a reaction gas at the manifold interface. Additionally, a second alignment protrusion forms the second slanted surface and aligns the unit cells accordingly.
