The bipolar plate gasket is a critical component within a fuel cell stack (or fuel cell assembly), forming the framework alongside the bipolar plates (BP) and end plates to ensure the fuel cell's proper operation and performance. Its primary functions include sealing the reaction gases to prevent leakage, supporting the membrane electrode assembly, and facilitating electrical and thermal conduction.
Functions of the Bipolar Plate Gasket
Gas Sealing: The gasket forms a tight seal with the bipolar plate, segregating reaction gases (such as hydrogen and oxygen) to prevent gas mixing and leakage, thereby safeguarding fuel cell safety and efficiency.
Supporting the Membrane Electrode Assembly: The gasket provides structural support for the membrane electrode assembly (MEA), ensuring its stability and longevity.
Electrical and Thermal Conductivity: The gasket facilitates the conduction of electrical current and thermal energy, aiding electrochemical reactions within the fuel cell and assisting in heat dissipation.
Assembly Support: Bipolar plates and gaskets collectively form the framework and foundation of the fuel cell stack, constituting a critical structural element for normal operation.
Composition of Bipolar Plate Gaskets
Gaskets are typically manufactured from polymeric materials exhibiting excellent corrosion resistance, elasticity, and sealing properties. These materials withstand the chemical and physical conditions encountered during fuel cell operation.
Significance
The quality of bipolar plate gaskets directly impacts fuel cell performance, efficiency, safety, and lifespan. High-quality gaskets effectively prevent gas leakage and internal short circuits, thereby enhancing the overall reliability of the stack.
