Highly conductive and efficient gas diffusion layer

Highly conductive and efficient gas diffusion layer

Combustion carbon paper is a key material in fuel cells, especially proton exchange membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC), and is a core component of the gas diffusion layer (GDL). It is located between the membrane electrode assembly (MEA) and the bipolar plate, and its main function is to evenly distribute reaction gases, conduct current, drain water, and support the catalyst layer.

Product Description

 
The combustion electric carbon paper mainly uses polyacrylonitrile (PAN) - based carbon fibers or asphalt based carbon fibers, which are subjected to high-temperature carbonization (>1000 ° C) treatment to form a highly conductive and stable carbon fiber network.
 
Possible addition of resin binders (such as phenolic resin) to enhance mechanical strength.
