Patent number: 11069914Abstract: An apparatus is provided to stack a fuel cell stack by pressurizing a separating plate component including a membrane-electrode assembly (MEA) sheet component, in which gas diffusion layers are bonded to both surfaces of an MEA, respectively. The apparatus includes a component aligning unit, a component stacking unit, a component pressurizing unit, an end plate loading unit, and a transferring unit. The transferring unit transfers a stack guide, on which a separate plate component and the MEA sheet component are stacked, to the component pressurizing unit. The transferring unit transfers a stack body, in which the separate plate component and the MEA sheet component are stacked, to a completion end of the transfer route of the stack guide, separately from the stack guide.Type: GrantFiled: April 23, 2019Date of Patent: July 20, 2021Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: HoKyun Ju, Yoon Jang
