NOVELTY - A proton conductive membrane comprises proton selective layer of 80-100% carbon with sp2 hybridization having a thickness of 0.3-100 nm, with remaining 0-20% of hydrogen, oxygen, nitrogen, and sp3 carbon. The sp2 carbon is in a form of graphene-like material. The proton selective layer has a set of pores formed by cyclical structures of any of 7, 8, 9 or 10 sp2 carbon atoms or their combination, with the pores having an effective diameter of up to 0.6 nm. An ionomeric polymer layer is provided on the proton selective layer, where a total thickness of the proton conductive membrane is less than 50 microns, and the proton conductive membrane is electrically non-conductive. USE - A proton conductive membrane. ADVANTAGE - The proton conductive membrane provides a very selective barrier with high proton conductance and rejection of molecular and ionic species. The main advantage of the formulation for rGO-based membranes is that they can be tuned to be proton conductive but with low crossover of molecules and ions. Because of the relatively low cost and scalability, good mechanical stability and, most importantly, extremely high specificity to protons with high proton conductance, makes such membranes to stand out from previous reported formulations as a unique specialty material.
