The thickness of the bipolar plate should be as thin as possible while maintaining a certain mechanical strength and good gas barrier effect to reduce the conductive resistance to current and heat.

Currently, the material of the bipolar plate can be roughly classified into 3 types: the graphite bipolar plate is the most commonly used bipolar plate in the prior art, and the flow field is formed by mechanically carving the surface of hard graphite.
