• Description
  • Specification
CeTech's carbon paper is specially developed for PEMFC and DMFC fuel cell applications and has consistently maintained a good performance in fuel cell efficiency tests. 

GDL210SHT is a carbon paper with a Microporous Layer (MPL) of total thickness by 0.21mm. It is with High Heat Treatment and a low-cost alternative to conventional carbon paper Gas Diffusion Layer (GDL) materials.


Advantages of Carbon Paper with Microporous Layer (MPL) :
Heat transfer during cell operation
Automated QC inspection system
Keep some water on the surface for conductivity
Avoid "flooding"
