Gas Diffusion Medium

GENPORT also provides SCCG series of Gas Diffusion Medium materials, produced by SAATI SpA, are multilayer materials having as substrate weaved fabrics based on spun carbon fibers. GDL are coated with an innovative hydrophobic plasma based treatment or conventional PTFE coatings. On top of these treatments, a conductive Micro Porous Layer (MPL) is added. This further layer ensures a better electrical contact with the adjacent catalyst substrate and allows effective water management from the cathode catalyst layer into the gas diffusion layer.
