Description

The sealing film is attached to the bipolar plates, and the shape of the sealing film is consistent with the sealing surface track of the bipolar plates. Considering the process cycle requirement, the sealing film is formed by laser cutting. Before cutting, the sealing film is a whole continuous body adsorbed on a cutting platform (also called a cutting chuck), and after cutting, the sealing film is divided into a finished product area, an inner waste area and an outer waste area.
