Carbon Paper

ProductDescription

Gas Diffusion Layer (GDL) is a veryimportant supporting material in a MEA, the heart of a fuel cell. GDL serves asa connect bridge between MEA and graphite plate, and the main functions of GDLinclude the followings:

 

1. A gas diffused pathway from flow channelsto the catalyst layer.

2. Help removing by-produced water outsideof the catalyst layer and prevent flooding.

3. Keep some water on surface forconductivity through the membrane.

4. Heat transfer during cell operation.

5. Provide enough mechanical strength tohold MEA from extension caused by water absorbance.

 

The CeTech Gas Diffusion Layer (GDL) isspecially developed as a carbon fiber paper and carbon fiber cloth for PEMFCand DMFC fuel cell applications. And CeTech GDL has well performance in thefuel cell efficiency test. The 2nd generation of carbon substrate has been welldeveloped, and the new substrate is presented with the better performance andproprieties. For the details, please find the sections of product N series andW series.
