Graphitized carbon fiber paper, woven carbon cloth, and PTFE/microporous-layer (MPL) coated Gas Diffusion Layers (GDL) for PEM fuel cells, CO2/N2 electroreduction, and redox flow batteries.
Engineered with controlled 75%–82% open macroporosity, high through-plane electrical/thermal conductivity, and customizable hydrophobicity, our graphitized carbon papers and woven carbon cloths manage simultaneous gas transport, water removal, and electron conduction across electrochemical membrane-electrode assemblies (MEAs).
Choose untreated hydrophilic grades for supercapacitors, microbial fuel cells, and vanadium redox flow batteries, or PTFE-wetproofed + carbon/PTFE Microporous Layer (MPL) coated GDL sheets for H2/O2 PEM fuel cells and gas-fed CO2/O2 electrolyzers.
