Powerful Benefits of Expanded Graphite BPA​

• 58% lower bipolar cost than incumbent coated stainless steel plates translates into a stack cost savings of $6/kW*​
• 30% thinner webs than other commercially available, expanded graphite plates translates into 13%** increased stack power density in customer terms.​
• Plate resin is 335% stronger than the market incumbent at peak operating temperature. Achieved by 2 years of formulation work.

Seal on Plate or MEA 

Our proprietary bipolar plate seal technology combines high-strength expanded graphite with precision elastomeric sealing to deliver unmatched durability and performance in fuel cell stacks. Using a low-pressure injection process, we achieve fast cycle times and reduced part counts while maintaining exceptional sealing integrity. This innovation not only enhances stack reliability under extreme conditions but also contributes to significant cost savings and increased power density.
