Sanergy™ LT – Precoated strip steel for PEFC bipolar plates

Coated Strip Steel

Scale up your production. Drive down manufacturing costs of bipolar plates for Polymer Electrolyte Fuel Cell (PEFC) applications. Sanergy™ LT technology hands you PVD coated coil in continuous lengths up to more than 10,000 meters. All with nanometer-level precision.

Sanergy™ LT – Precoated strip steel for PEFC bipolar plates

The low-cost stainless-steel substrate delivers economy and durability for 2D and 3D plates. The multi-layer graphite surface offers high corrosion resistance, low gas permeability and enhanced conductivity. Add an integrated approach with fewer steps and less logistics and more efficient industrial mass production of 3D bipolar plates for PEFC is all yours.

We produce coated strip for PEFC bipolar plates using a technologically advanced, environmentally-friendly vacuum-coating process, applied to long continuous lengths. No more waiting for sub-suppliers to coat individual plates. Just forming and stamping at scale.

Any non-conforming surfaces are easily identified and cut away, thanks to full traceability, quality controls and a map report. And based on your plate geometry, we’ll help you find the optimum coil width and slit to minimize scrap.

Why Sanergy™ LT coated strip steel for PEFC bipolar plates

  • Low interfacial contact resistance (meets US Dept. of Energy requirements of < 10 mΩ cm2) on a par with gold but less costly
  • Uniform multi-layer coating with nanometer precision
  • Good corrosion resistance in PEFC environment (< 1 µA/cm2)
  • Low electrical degradation (typically less than 0.5%/1000 h)
  • Good processing and forming characteristics
