This production line is used for automatic inspection of incoming bipolar plates before stacking, improving the first-pass yield of finished fuel cell stacks.

The inspection scope includes warpage, airtightness, AOI inspection (color difference on both sides, creases, scratches, white spots, dirt, black spots, film peeling, etc.)
