• Description
  • Specification
Carbon plate  is primarily used as the gas diffusion layer (GDL) in fuel cells. Its functions include supporting the catalyst layer, conducting gas and current, and removing water produced by the reaction. The thickness, pore structure, and material properties of thick carbon paper are crucial to fuel cell performance. It serves as a vital bridge between the membrane electrode assembly (MEA) and the bipolar plate.

**Key Functions**
Gas Distribution: They feature flow channels to deliver fuel (e.g., hydrogen) and oxidant (e.g., oxygen) to the membrane electrode assembly (MEA).
Structural Support: The plates provide mechanical strength to the fuel cell stack, which is crucial for high-pressure operation and durability.
