Gas Diffusion Layer (GDL) sheets are porous, graphitized, resin bonded carbon fiber papers and multi-ply panels specifically designed for use in PEM, AEM, DMFC and PAFC fuel cells, Electrolyzers, Humidifiers and Other Electrochemical Devices.
These products are optimized, among other, for their electrical conductivity, mechanical strength and durability, gas/air permeability and water management. Spectracarb GDLs are produced in the USA and are available in a wide range of standard and custom grades, densities, sizes and materials for fuel cells, electrolyzers, humidifiers, specialty batteries and other electrochemical applications. They can be coated, inked or loaded as Anode or Cathode catalyst layers for Membrane electrode assemblies. CAPLINQ offers the full range of GinerELX (previously known as Engineered Fibers Technology) product line.
All of our default Gas difussion layer panel sizes are either 40 x 40cm or 55 x 55 cm with custom sizes available for special orders and larger quantities. Sheet thicknesses range from as low as 1.9mm (75mil) to as thick as 22mm (840mil). Densities of the panels range from as low as 0.5 g/cc to 0.775 g/cc.
Custom sizes, machined discs, and other customer defined shapes, as well as machining, water proofing and surface grinding services are also available. Contact us with your query.
