Toray Carbon Paper without MPL – TGP-H-090 (Hydrophilic)

Description

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.
