Product Description

Spectracarb™ 2050A-1050 Gas Diffusion Layer (GDL) is a standard grade carbon paper GDL that is very similar to Toray Carbon Paper 090.  It is used mainly in Polymer Electrolyte Membrane (PEM) fuel cells for transportation, including automotive and fuel cell buses, as well as for general development.

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.
