PURPOSE: A fuel cell stack for vehicles is provided to improve air tightness between a separator and a membrane-electrode assembly through a gasket and to prevent the performance degradation of fuel cells. CONSTITUTION: A fuel cell stack(100) for vehicles includes an electricity generation assembly(10) by unit cells(11). The unit cell comprises a membrane-electrode assembly(21), separator(31), and a gasket(40) formed between the separator and the membrane-electrode assembly. The separator includes channel regions(CH1,CH2) enabling the flow of reactive sources of fuel or oxidizing material and cooling medium, and a plurality of manifolds(51,52,53) formed as an inlet and an outlet of the cooling medium and the reactive source. |
