ABSTRACT:
A system for feeding a fuel cell stack including fuel cells having separating plates and membrane electrode assemblies (MEAs). The system includes a separating plate supply unit for feeding the separating plates; an MEA supply unit for feeding the MEAs; a feeding unit on which the separating plates and the MEAs are fed, the feeding unit being configured to move upward and downward; and a transfer unit for receiving the separating plates and the MEAs from the separating plate supply unit and the MEA supply unit, respectively, and for loading the separating plates and the MEAs onto the feeding unit. A method for feeding a fuel cell stack includes feeding one of the separating plates, moving a magazine a predetermined amount, lowering a plate of a feeding unit, feeding one of the MEAs, and determining if the separating plates and the MEAs have been fed as much as a required number.
