AI Technical Summary
Existing bipolar plates in water electrolyzers suffer from problems such as large metal consumption, complex processing, heavy weight, high cost, easy detachment of sealing rings, inability to withstand high voltage, and high concentration of metal ions in the electrolyte.
It adopts injection-molded non-metallic frame bipolar plates, combined with the umbrella-shaped structure of the sealing ring. The concentric ring design of the non-metallic frame and the metal partition ensures sealing and pressure resistance, reduces the contact between metal and electrolyte, and uses easy-to-inject-mold plastic materials such as PP or ABS.
It achieves lightweight design, reduces processing difficulty and cost, improves sealing and safety, reduces the entry of metal ions into the electrolyte, extends the electrolyte replacement cycle, and enhances the high-pressure stability of the electrolytic cell and the purity of hydrogen and oxygen.
