Toray Carbon Paper TGP-H-090 (Hydrophobic, With MPL), 3 Sheets
Product Name & Description
Toray Carbon Paper TGP-H-090 with MPL is a carbon fiber composite used as a gas diffusion layer (GDL) and catalyst backing material for fuel cells and electrochemical applications.
It features a 280 μm substrate with ~60 μm MPL (total ~340 μm). The substrate (~8–10 wt% PTFE) and MPL (~33–35 wt% PTFE) provide hydrophobic performance for efficient water management.
