Disclosed are a metal separation plate for a fuel cell stack, and a fuel cell stack having the same. The metal separation plate not only can enhance cooling performance and stack performance but also can enhance humidification performance of a membrane-electrode assembly by blocking moisture released from a closed air flow channel. The metal separation plate include a metal separation plate main body and a gasket. The metal separation plate main body includes: a channel part which separately protrudes to form a matrix array in the direction from a lower side to an upper side, has an open portion, and has a side portion opened in the direction of a short side or a long side and the other side portion having the closed air flow channel; and a manifold part that includes a reaction gas inlet and a reaction gas outlet which are arranged on both edges of the channel part. The gasket includes: a first gasket, formed along an edge of the manifold on an upper surface of the metal separation plate main body, and a second gasket, which is located on an edge of the channel part and is alternately arranged with the protrusion pattern in an island structure. |
