Product Uses
• Carbon Plastic Graphite Bipolar Plate are also known as carbon-polymer composite (CPC).
• Carbon-Polymer Composite (CPC) – "Cost-Leader for GW Scale"
• Gradient-expanded-graphite + PP formulation (patent pending) replaces PVDF, cutting raw-material cost 35 %.
83 % voltaic & 80 % energy efficiency at 200 mA cm⁻², 25 °C .
Acid uptake < 0.3 wt % after 1 000 h immersion; projected corrosion rate < 3 µm yr⁻¹, matching 20-year VRFB duty.
Price target ≈ 25 % below incumbent European CPC plates.
