Freudenberg H23C6 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 recommended for highly humidified stationary LT-PEMFC systems. It is 250 um (microns) thick.

Freudenberg H23C6 is recommended for:

• Highly humidified stationary Low Temperature Polymer Electrolyte Membrane Fuel Cell Cells (LT-PEMFC) systems
• Highly humidified LT-PEMFC Stationary CHP applications
• LT-PEMFC Automotive applications

Freudenberg H23C6 is formerly known as H2315 I2 C6.
