A fuel cell stack is provided to prevent the temperature degradation of a fuel battery cell near an end plate and to improve cooling starting by reducing the contact area between a current collector and an end plate by changing a structure of the end plate. A fuel cell stack for vehicles comprises a plurality of cells(15), a separator(14), a current collector(12) and an end plate(10). A plurality of grooves(11) is formed at the front side contacting an end plate and the current collector and is formed with an air layer between the end plate and the current collector. |
