Gas Diffusion Layers (GDLs) are critical components in PEM fuel cells, electrolyzers, redox flow batteries, and other electrochemical devices. They provide gas diffusion, water management, electrical conductivity, and mechanical support to the catalyst layer.
The Fuel Cell Store carries one of the largest selections of Gas Diffusion Layers in the world! Use the interactive comparison table below (or download the full Excel/PDF file) to easily compare specifications across Carbon Paper, Carbon Cloth, Felts, and specialty materials.
If you need help selecting the right GDL for your application, contact us at sales@fuelcellstore.com or call (979) 703-1925.

Overview of GDL Types
- Carbon Paper GDLs: Rigid structure with excellent uniformity. Available with or without PTFE treatment and Microporous Layers (MPL).
- Carbon Cloth GDLs: Flexible and highly compressible. Great for applications requiring good mechanical resilience.
- Felts: Very thick and porous — ideal for flow batteries, electrolyzers, and high-mass-transport applications.
- Other Materials: Metal-based options (Nickel, Titanium) for specialized corrosive environments or high conductivity needs.
