Function of Bipolar Plate in Fuel Cell

The bipolar plate is a critical component in fuel cells, serving three key roles:

Electrical Conduction – Connects cells in series to form a stack while conducting current.
Gas Distribution – Delivers hydrogen (anode) and oxygen (cathode) via flow channels to catalyst layers.
Heat & Water Management – Helps dissipate heat and removes water byproduct to prevent flooding.

Made of graphite, metal, or composites, it must balance conductivity, corrosion resistance, and lightweight design for optimal performance.
