SpectracarbTM GDL papers and panels consist of graphitized resin bonded carbon fibers that form porous sheets, with high electrical / thermal conductivity and chemical / corrosion resistance that control the proper flow of reactant gases (hydrogen and air) and the water transport in the membrane electrode assembly (MEA).

Our Spectracarb production efforts have focused mainly on specialty processed thin papers and laminated multi-ply panels, with a wide range of densities and thicknesses ranging from 0.25 g/cm3 and one-tenth of a millimeter to 0.90 g/cm3 and four-millimeters, respectively. All Spectracarb GDL products are made in the USA.
