Gas Diffusion Layer Toray TCP-H is a Carbon-Carbon Composite Paper which has been used for PAFC and PEFC for decades and has proven durability. Its high mechanical strength, conductivity and gas permeability are suitable for use as a Gas Diffusion Layer (GDL) in fuel cell applications. Characteristics • High strength Read more…
GDLs are typically designed as a bilayer structure consisting of a macro-porous backing material (carbon fiber paper support) and a micro-porous, carbon-based layer (MPL). The fibrous backing material governs the mechanical properties of the GDL (behavior upon compression, bending and shear strength, etc.) while the MPL ensures intimate contact to Read more…
Freudenberg produces a comprehensive range of Gas Diffusion Layers (GDL) designed to meet all operative conditions and requirements in Hydrogen (PEMFC) and Direct Methanol Fuel Cells (DMFC). The Gas Diffusion Layers are manufactured using Freudenberg’s proprietary nonwoven technology. This enables a high degree of design flexibility to meet the specific Read more…
