Toray Paper- TGP-T-060 - 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 190 um (microns) and the MPL has a thickness of 60 microns. This product has a total thickness of approximately 250 microns. Toray Paper 060 has a PTFE treatment of approx. 8-9% and the MPL has a PTFE content of approx. 33-35%. Toray Paper 060 with MPL is a great low-cost alternative to conventional woven carbon cloth Gas Diffusion Layer (GDL) materials. Toray Paper 060 has a standard PTFE wet proofing (which is 8-9%).
