Freudenberg H14C15 is a flexible and easy to use carbon paper Gas Diffusion Layer (GDL) with a Microporous Layer (MPL) as well as a hydrophobic treatment. It is 145 um (microns) thick @ 1 MPa compression.

Freudenberg H14C15 is recommended for:

• LT-PEMFC Automotive applications
• LT-PEMFC Stationary CHP High Humidification
• Applications requiring a very thin GDL with a MicroPorous Layer (MPL)
