PTFE flat porous disc-shaped membranes laminated with polypropylene (PP) (the PTFE side is used as the feed side, while the PP or support side is used as the permeate side), with pore diameter (d pores) of 220 nm and membrane diameter (d membrane) of 47mm, were purchased from Filtres-Fioroni, while PVA granules (M w = 205,000 g/mol, 88 mol

addition of 30% PTFE at 0.45 V [22]. However, the amount of PTFE has a significant effect on fuel cell performance, as electrical conductivity decreases due to an increasing amount of PTFE. The optimum PTFE proportion that should be used is between 10% and 30% [15,16,18,23]. Cabasso et al. prepared a 50–300-µm-thick GDL surface with a

The PTFE membrane can be classified based on the mechanism as, the membrane that gets wet with water and the membrane that gets wet with low surface tension liquids. Both the types of PTFE membranes offer filtration of air, gases and fluids as the primary application, since the PTFE membrane is biologically and chemically inert and is a stable
