Toray Carbon Fiber Paper with MPL -TGP-H-090 (Hydrophobic)

Description

Product Name & Description

Toray Paper TGP-H-090 – is a carbon fiber composite paper suitable for use as a catalyst backing layer for fuel cells, electrolyzers, batteries, and various other electrochemical devices after applying a microporous layer (MPL) onto it. The carbon paper susbtrate has a thickness of 280 um (microns) and the MPL has a thickness of 60 microns. This product has a total thickness of approximately 340 microns. Toray Paper 090 has a PTFE treatment of approx. 8-9% and the MPL has a PTFE content of approx. 33-35%. Toray Carbon Paper 090 with MPL is a great low-cost alternative to conventional woven carbon cloth Gas Diffusion Layer (GDL) materials.
