Carbon-Polymer(Carbon-Plastic) composite bipolar plates generally manufactured by extruding or molding conductive carbon based raw materials and resins. Carbon based raw materials include carbon black, graphite, carbon fiber, etc, which are added to resins to offer conductivity for bipolar plates. Resin such as PP or PE …

Based on different materials, bipolar plates can be divided into graphitic bipolar plates, metallic bipolar plates and composite bipolar plates, and Bpps with different materials have completely different manufacturing processes. Generally, metal bipolar plates are easy to process and realize mass production, but their disadvantage …

The type of bipolar plate flow channel determines the state of the reactants and products in flow field. A flow field with reasonable design can make the reactants uniformly distributed on electrode and timely discharge water, fully ensure good stability and performance of battery stack. …
