CT GDL240 is a carbon paper with a Microporous Layer (MPL). It has a total thickness of 240 um (microns). CT is a great low-cost alternative to conventional carbon paper Gas Diffusion Layer (GDL) materials.

CT GDL240 is available in 20 x 20 cm or 40 x 40 cm sheets at this time.

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