Sigracet

SIGRACET Gas Diffusion Layers (GDL) are “graphitized“ carbon fiber-based nonwovens, either papers or felts, specifically designed to transport reactant gases into and excess liquid product water out of the electrocatalyst layers of Proton Exchange Membrane (PEM) fuel cells.

Typical standard grades for general applications are GDL 24/25 BC, GDL 10 BC and GDL 34/35 BC but through different hydrophobicity levels and materials with/without microporous layers, SIGRACET GDLs can cater to virtually all standard or special applications including niche markets.
