· Special plugging process and exclusive formulation of graphite modifier to ensure zero leakage under operating conditions for more than 20,000 hours
· Special surface processing technology to ensure contact resistance ≤ 5mΩcm2
· Exclusively designed and developed large-area bipolar plate, the power per liter is greatly improved
· Light milling process, the plate can be as thin as 0.5mm (milling on one side)/0.8mm (milling on both sides)
