Surface Inspection of Bipolar Plates for Fuel Cells

Hydrogen and fuel cells will make an important contribution to the electrification of drives in the future. As a key technology, they already play a decisive role in the transformation of the energy sector.

The quality of each individual bipolar plate has a significant influence on the function and performance of the entire fuel cell. Therefore, quality assurance within the complete production process via testing and identification systems is necessary.

Challenge

• Complex production process
• High vertical range of manufacture
• Components in different states

The demanding, meandering surface geometry of the active zone poses a particular challenge. Different brightnesses and highly specular properties of the component require special solution approaches that reliably detect all defined defects and still allow for a minimum pseudo-defect fraction.
