AvCarb Material Solution’s Gas Diffusion System GDS22100 combines AvCarb's proprietary carbon fiber paper, a PTFE treatment, and micro-porous layer coating, designed for the rigorous demands of specific fuel cell applications such as Proton Exchange Membrane Fuel Cells (PEMFC), Direct Methanol Fuel Cells (DMFC), and Phosphoric Acid Fuel Cells (PAFC).

AvCarb GDS22100 gas diffusion layer is highly recommended for Direct Methanol Fuel Cell (DMFC) anode (passive) applications.
