  • Patent number: 11069914
    Abstract: 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.

  • Patent number: 10312543
    Abstract: An apparatus is provided to stack a fuel cell stack by stacking and pressurizing a separating plate components, including a membrane-electrode assembly (MEA) sheet component, in which gas diffusion layers are bonded to both surfaces of an MEA, respectively. A component stacking unit is installed at in a frame and grips the separating plate component and the MEA sheet component and stacks the components on a stack guide. A component pressurizing unit is installed at an upper side of a transfer route, through which the stack guide is transferred, and pressurizes the separating plate component and the MEA sheet component stacked on the stack guide. An end plate loading unit grips each of upper and lower end plates and loads them onto the stack guide. A transferring unit transfer a stack body of the separating plate component and the MEA to a complete end of the transfer route.
