- 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.
GDS250 is a carbon paper substrate without a Microporous Layer (MPL). It has a total thickness of 0.25mm and with low-cost alternative to conventional carbon paper Gas Diffusion Layer (GDL) materials.
GDS250 is a carbon paper substrate without a Microporous Layer (MPL). It has a total thickness of 0.25mm and with 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"
