  • Publication number: 20230402640
    Abstract: An apparatus for manufacturing a unit cell cuts lower and upper separators between sets of adjacent electrodes. In a state of a process of manufacturing the unit cell, the lower and upper separators continuously move in a longitudinal direction; and the electrodes are stacked between the separators and on the upper separator, respectively. The apparatus includes a lower block disposed under the lower separator and an upper block vertically aligned with the lower block above the upper separator. A lower end of a cutter is installed for access to the inside and outside. The upper block descends to press the separators to a surface of the lower block. One or both of the upper and lower blocks is heated to a predetermined temperature to thermally fuse pressed points of the separators. The cutter protrudes from the upper block to perform cutting at points at which the separators are pressed.
