Bipolar plates are core components in the stacks of proton exchange membrane fuel cells and flow batteries. They have multiple jobs: carrying electric current, spreading reaction media, providing structural support, and separating the positive and negative sides. The choice of material for bipolar plates directly …

Bipolar plates are core components in fuel cells, water electrolysis equipment for hydrogen production and flow batteries. They perform multiple functions: separating reaction media, collecting and conducting electric current, distributing reactant gases or liquids evenly, and supporting the membrane electrode assembly. An ideal bipolar plate …

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 …
