GDL
â‘  GDL(Gas Diffusion Layer)
  • Fuel cell parts
  • Hydrogen and oxygen gas diffusion layer
  • Electron transfer
  • eactant(H2O) transfer
â‘¡ GDL Configuration
  • Composed of carbon paper or carbon veil and MPL(micro porous Layer)
  • Carbon paper and carbon veil are manufactured using carbon fiber
  • MPL is manufactured by mixing PTFE binder(water repellent) and Carbon
Division Backing Materia MPL(micro porous layer)
Material Carbon paper or Carbon veil(PAN* series carbon fiber is) Carbon + PTFE binder
Pore size More than 50㎚ Less than 2㎚
Function Mechanical characteristics (Compression, bending, shear strength) Securing the contact with the catalyst layer, protecting the PEM, Reactant(H2O) release and storage
