Production Line Overview:

This production line is used for the inspection of PEM hydrogen electrolyzer bipolar plates before stacking. The inspection scope includes flatness (warpage), airtightness, AOI inspection (color difference on both sides, dents, protrusions, plate cracking, scratches, white spots, dirt, black spots, edge deformation, adhesive overflow, adhesive line size inspection, etc.). This helps improve the first-pass qualification rate of electrolyzer stacking.
