Overview

Details

The 22BB GDL Carbon Paper (SGL SIGRACET Gas Diffusion Layer) is developed for use as a gas diffusion layer in electrochemical devices such as fuel cells, water electrolyzers, and carbon dioxide reduction systems. This carbon paper features a hydrophobic microporous layer (MPL) coated on a PTFE-treated substrate, with the surface layer containing 5% PTFE and the MPL incorporating 20–25% PTFE for enhanced waterproofing (water contact angle >130°). Compared to the BC variant, the BB model offers higher air permeability and porosity, making it suitable for applications requiring efficient gas transport. Its tailored hydrophobic properties and microporous structure support stable performance in aqueous environments, contributing to improved mass transfer and durability in catalytic processes.

1, this product is carbon paper with hydrophobic microporous layer. as the 1 gas diffusion layer, it is widely used in fuel cell, water electrolysis, carbon dioxide reduction and other fields.

2, the surface layer is 5% pfte coating, MPL also contains 20-25% PTFE, this hydrophobic treatment enables both layers to produce waterproof performance, (water contact angle & gt;130 °

the difference between different models:

BB: PTFE layer and microporous layer. This type of carbon paper was treated with PTFE hydrophobicity and coated with a layer of MPL (microporous layer).

BC: There is a PTFE layer and a microporous layer. Compared with the BB model, the BC model has an increase in mass per unit area and a decrease in air permeability and porosity.
