Description
Overview
GDL280 and GDL340 are carbon papers with porous layer and PTFE treatment, designed for use as gas diffusion layers in PEM fuel cells, water electrolyzers and other electrochemical devices. They provide effective gas transport, electrical conductivity and mechanical support within electrode assemblies. Belonging to the same product family, GDL280 has a typical thickness of 0.28 mm and GDL340 has a typical thickness of 0.34 mm. Both grades offer low through-plane resistance, good air permeability and reliable mechanical strength, making them suitable for research, pilot-scale and industrial hydrogen energy applications.
