CNB-1-TC13
Toray Carbon Paper without MPL - TGP-H-090 (Hydrophilic) ,3 sheets
Product Name & Description
Toray Paper TGP-H-090 - is a carbon fiber composite paper suitable for use as a catalyst backing layer. It has a total thickness of 280 um (microns). Toray Paper TGP-H-090 is a great low-cost alternative to conventional woven carbon cloth Gas Diffusion Layer (GDL) materials.
Toray carbon paper TGP-H-090 comes with a minimum of 5% weight wet proofing. The Teflon gives the carbon material a hydrophobic property to better function as an electrode backing material.
