Your cart is empty. Toray Carbon Paper, 20 x 20 cm size. No polytetrafluoroethylene (PTFE) treatment. CAS No. 7782-42-5
Toray TGP-H is a carbon-carbon composite paper which has been used for polymer electrolyte fuel cell (PEFC) and phosphoric acid fuel cell (PAFC) for decades and has proven durability. Its high mechanical strength, conductivity and gas permeability along with minimal electrochemical corrosion are suitable for use as a gas diffusion layer (GDL) in fuel cell applications.
TGP-H is made of polyacrylonitrile (PAN) carbon fiber ("TORAYCA") featuring high tensile strengh and high modulus.
