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
• Excellent gas permeability and low electrical resistivity
• Good handling
• Minimal electrochemical corrosion
