Abstract
An apparatus for manufacturing a unit cell including a first and second roller is provided. The first roller is positioned on a first side of the first and second separators. The second roller is positioned on a second side of the first and second separators opposite the first side wherein the second roller is aligned with the first roller along an axis and defines an oval shape having a long axis and a short axis. The second roller is configured to contact the second separator and press the first and second separators against the first roller at portions of the first and second separators which are between adjacent electrodes. One of the lower roller or the upper roller is heated so as to thermally fuse the separators together.
