PURPOSE: A multi-stage stack assembly of fuel cell system is provided to simplify a manifold structure formed on a same separator and minimize volume of stacks in multi-stage stack assembly which unit cells are laminated. CONSTITUTION: A multi-stage stack assembly(100) of fuel cell system which is formed by lamination of multi unit cells(110a-110e) includes at least one of gas supply plates(121,122) respectively formed in both sides of a first unit cell locating among in the center of a plurality of laminated multi-stage. The unit cell comprises a membrane-electrode assembly which is consisted of a polymer electrolyte membrane, and a separator formed in both sides of the film - electrode assembly. The multi-stage stack assembly additionally includes current collectors(141,142), insulating plates(151,152), and compressive plates(161,62) which are respective and successively laminated on both sides of the stack. |
