Document Type and Number:
WIPO Patent Application WO/2021/033932
Kind Code:
A1
Abstract:
Equipment for manufacturing a separator for a fuel cell according to the present invention comprises: a press which receives a conveyed first metal strip and second metal strip that are unwound from a first uncoiler and a second uncoiler, respectively, vertically arranges the metal strips side by side, and forms patterns on each of the first metal strip and the second metal strip; a welding machine which is disposed adjacent to the press, overlaps the first metal strip and the second metal strip conveyed from the press, and integrally joins the metal strips by welding same in a state in which the patterns are aligned face-to-face with each other; and a plurality of guide rolls which are arranged in front of and behind the press and guide the first metal strip so that the first metal strip is supplied to the welding machine at an overlapping position with the second metal strip after passing through the press at a position spaced vertically apart from the second metal strip. The patterns may include: a first alignment hole, one among a cathode plate pattern and an anode plate pattern, and a trimming hole, which are formed in the first metal strip; and a second alignment hole, the other among the cathode plate pattern and the anode plate pattern, and a trimming hole, which are formed in the second metal strip.
