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.
