Disclosed herein is a fuel cell stack structure, including: metallic bipolar plates having cooling surfaces facing each other, wherein film-removed portions are provided at portions of the cooling surfaces. The fuel cell stack structure is advantageous in that electrical conductivity can be achieved by the contact portion of two metallic bipolar plates without having to apply a conductive material onto the contact site of the cooling surfaces of the metallic bipolar plates, so that the manufacturing cost of the metallic bipolar plate can be reduced, thereby reducing the manufacturing cost a fuel cell stack.
