AvCarb Material Solution’s Gas Diffusion System MB30 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).

Electrochemical Performance of Avcarb MB30 in a Single Cell Configuration:

The following IV curve provides the electrochemical performance of Avcarb MB30 GDL as the cathode GDL. The anode side GDL was composed of Avcarb GDS3260 GDL (Source: June 2020 Newsletter by Avcarb). Use of proper GDL materials for anode and cathode will increase the performance significantly and reduce membrane drying out or prevent flooding inside the cell.

AvCarb EP40 is the base carbon paper material used in the making of the gas diffusion system MB30.
