Fuel cell technology
Non-destructive analysis of functional surfaces near the production line
Optical 3D surface measurement technology makes an important contribution to the development of efficient and powerful fuel cells. Decisive for their degree of efficiency are micro-geometries of inlying areas and channels through which hydrogen and air flow. Additionally, measuring options and results aim at the further miniaturization of fuel cells.
To meet these requirements, the NanoFocus product lines µscan and µsprint are suitable measurement systems. Both technologies deliver measurement results in the micrometer and nanometer range. Low-reflective and dark graphite surfaces can be analyzed reliably which is not possible with triangulation or image processing systems. All measurements are performed without destruction or previous preparation of the surface.
Examples of application
The NanoFocus optical 3D measurement systems are applied in research and development, different stages of production, as well as in quality control of fuel cells. NanoFocus offers reliable solutions for random sample measurements close to production, as well as for 100% inspections.
Measurements at the MEA (SOFC)
Measurements on bipolar plates
The ribbed surfaces of bipolar plates (BPP) must be inspected for defects in the form of connectors and tips. The µsprint technology allows the measurement of complete plates including the evaluation and result display within only 30 seconds.
