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.
Did you stumble upon us while looking for a legacy product code?
In December 2018 GinerELX acquired the entirety of the Engineered Fibers Technology (EFT) company including branding, manufacturing, stock and all of the company’s assets while naturally inheriting their entire customer base. Caplinq Europe BV remains the European representative of Spectracarb products. As part of their acquisition, GinerELX analyzed the existing business model and realized that they had to completely transform and reorganize the costs and production lines, reevaluate the product portfolio and manufacturing process to ensure that they can continue providing exceptional quality and service.
As a result, effective August the 1st, GinerELX has adapted or completely removed some of the product lines to reflect the services GinerELX’s clients mostly need.
The renewed/remaining products are the ones listed in our Product selector guide. If the products you used to find are not listed then they are discontinued.
