CeTech Carbon Cloth，W0S1011

Product Overview

CeTech Carbon Cloth is a woven carbon fiber gas diffusion material designed for fuel cell and electrochemical energy applications.

The carbon cloth features excellent electrical conductivity, high mechanical compressibility, and stable gas transport performance, making it a cost-effective alternative to conventional carbon paper GDL materials.

Two configurations are available:

•W0S1011 – Carbon cloth without MPL or PTFE treatment

•W1S1011 – Carbon cloth with microporous layer (MPL) and PTFE treatment

Both versions are widely used in PEM fuel cells, electrolyzers, metal-air batteries, and gas diffusion electrochemical systems.
