WHAT ARE BIPOLAR PLATES?

Bipolar plates are essential for fuel cells (PEM, alkaline, and solid oxide) and electrolyzers, serving as multifunctional cores that:

Deliver precisely etched flow channels for uniform gas distribution (H₂/O₂/air),

Facilitate high electrical conductivity across stacked cells, and

Maximize system efficiency, durability, and power output in hydrogen technologies.
