PURPOSE: A multi-stage type fuel cell stack is provided to increase powder density of a stack, to prevent excessive or low humidification, and to improve stability of performance of a fuel battery. CONSTITUTION: A multi-stage type fuel cell stack integrated with a gas-liquid separator comprises a stack bodies in which a plurality of unit cells which comprises a membrane-electrode assembly and separator are laminated, and a gas supply element(20) arranged between the plurality of stack bodies. The gas supply plate element electrically connects each of the stack bodies arranged in both sides, receives reaction gas which is primary reacted in a stack arranged in one side, separates gas and liquid in the reaction gas, and makes the reaction gas flow to a stack in the other side. |
