Product Name & Description

Toray Paper TGP-H-060 with MPL is a carbon fiber composite paper used as a gas diffusion layer (GDL) and catalyst backing material for fuel cells and other electrochemical applications.

It features a 190 μm carbon substrate with an additional ~60 μm MPL, giving a total thickness of ~250 μm. The substrate (~8–10 wt% PTFE) and MPL (~33–35 wt% PTFE) provide hydrophobic properties for improved water management.
