Spectracarb GDL 2050 Series Sizes, Thicknesses and Densities

All of the Spectracarb 2050 Series GDL sheet sizes are 400 x 400 mm for thin (paper) grades, and 450 x 450 mm for laminated panels, with sizes up to 550 x 550 mm available as special order. Sheet thicknesses range from as low as 5 mils (125 micron) to as thick as 200 mils (5 millimeters). Densities of the panels range from as low as 0.25 g/cc to 1 g/cc. Custom sizes, machined discs, and other customer defined sizes and shapes, as well as machining such as channels and surface grinding are also available.

Spectracarb GDL 2050 Series Grades

  • 2050 A: Standard grade 2050A is our base series graphitized paper and panels used mainly in PEM fuel cells and electrolyzers. Properties of thin papers comparable with other GDL’s used in industry, but with wider selection of density and thickness.
  • 2050 HF: Other special grades include “2050 HF” with higher mean pore size and increased permeability.
  • 2050 HT: Spectracarb GDL can also be manufactured in the density and thickness ranges shown above, but using modified processing to achieve higher electrical conductivity and improved corrosion resistance with our ”2050 HT” Series for use in PAFC and other special products.
  • 2050 L: Spectracarb GDL thin papers and thicker panels can also be provided on special order in a “2050 L” grade which is carbonized at a lower maximum temperature to provide a lower cost product for humidifiers and other special products.
  • 2050 P: Both papers and panels can also be provided on special order in our “2050 P Series” where additional purification can be conducted to provide trace elements <0.5 ppm.
  • 2050 WP: Wet proofed grades incorporating a microporous hydrophobic layer of any of the Spectracarb series can be provided through a partner company.
  • Customer Specific Grades: It is also possible to make Hybrid constructions in the Multi-layer constructions. Contact us to discuss any special requirements, or for the design and production of grades for your specific requirement.
