Fuel Cell Manufacturing
Increase cell efficiency by employing advanced bipolar plate geometries, enabled with ARM fiber laser welding.
- High Speed Weld bipolar plates at high throughput speeds without sacrificing quality.
- Dense Welds Improve weld density with the fine control possible through ARM technology.
- Increased Conductivity Get higher conductivity welds for improved battery performance.
Production Welding
Welding membrane electrode assemblies (MEAs) between bipolar plates is a key step in fuel cell production. Because of the large number of MEAs used in each fuel, this welding must be performed at high speed to make the assembly process economically viable. But traditional fiber lasers haven't delivered the necessary weld quality, and tend to produce “humping” in the weld seams. Coherent HighLight FL-ARM lasers solve this problem and enable cost-effective bipolar plate welding.
