Product Description

Spectracarb™ 2050A-1535 Gas Diffusion Layer (GDL) is a heavy duty porous graphitized carbon sheet with low compressibility and with general utility for a range of PEM fuel cell applications, including both commercial and military applications. This GDL has very similar properties to that of Toray Carbon Paper 120.

Spectracarb™ 2050A-1535 (0.35 g/cm³)

Spectracarb 2050 Gas Diffusion Layer (GDL) sheets are porous “graphitized” resin bonded carbon fiber papers and multi-ply panels specifically designed for use in PEM, DMFC and PAFC fuel cells, Electrolyzers, Humidifiers and other Electrochemical Devices and optimized for:

  • Electrical Conductivity
  • Mechanical Strength and Durability
  • Gas/Air Permeability
  • 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.
