This production line is used for automatic inspection of incoming membrane electrode materials before stack assembly, improving the first-pass yield of finished fuel cell stacks.

The inspection scope includes thickness, air tightness, front and back contamination, carbon paper damage, cracks, detachment, dents, frame bubbles, foreign objects, etc.
