Toray Paper 120 - TGP-H-120 - is a carbon fiber composite paper suitable for use as a catalyst backing layer for fuel cells, electrolyzers, batteries, and various other electrochemical device applications after applying a microporous layer (MPL) onto it. The carbon paper substrate has a thickness of 370 microns and the MPL section has a thickness of 60 microns. This product has a total thickness of approximately 430 microns. Toray Paper 120 has a PTFE treatment of approx. 8-9% and the MPL has a PTFE content of approx. 33-35%. Toray Carbon Paper 120 with MPL is a great low-cost alternative to conventional woven carbon cloth Gas Diffusion Layer (GDL) materials.

Specifications:

• Dimensions: 9.5 x 9.5 cm or 20 x 20 cm

Toray Paper 120 has a standard PTFE wet proofing (which is 8-9%).
