CT GDL340 is a carbon paper with a Microporous Layer (MPL). It has a total thickness of 340 um (microns). CT is a great low-cost alternative to conventional carbon paper Gas Diffusion Layer (GDL) materials.

CT GDL340 is available in 20 x 20 cm or 40 x 40 cm sheets at this time.

Advantages of CT Carbon Paper:

  • Heat transfer during cell operation
  • Automated QC inspection system
  • Keep some water on the surface for conductivity
  • Avoid “flooding”
