New application of supported ionic liquids membranes as proton exchange membranes in microbial fuel cell for waste water treatment

New application of polymer inclusion membrane based on ionic liquids as proton exchange membrane in microbial fuel cell

“…In the case of PILIM the voltage is maintained for longer than for SILM, maybe due to the higher stability of the former. However, comparing PILIMs and SILMs with similar ionic liquid concentration, higher voltages are reached in SILMs than in PILIMs [47]. The higher immobilization of the ionic liquids in the PILIM membranes reduce the ionic liquid mobility and thereby their proton conductivity.…”

Biological Fuel Cells and Membranes

“…The PD-coated UF membrane resulted in a high power density (159 mW/m 2 ), whereas the untreated UF membrane produced a power density of 137.9 mW/m 2 —approximately 15% less than the power density achieved by the previous PD-coated UF [57]. Recently, Hernández-Fernández et al [58] employed a newly fabricated ionic liquids membrane as the PEM in a MFC for waterwaste treatment. The supported ionic liquid membranes comprised of 1- n -alkyl-3-methylimidazolium ( n -butyl, n -octyl) and methyl trioctylammonium cations combined with hexafluorophosphate, tetrafluoroborate, chloride, and bis{(trifluoromethyl)sulfonyl}imide anions.…”

Nafion and Ultrex were used as reference membranes [58]. The fabrication of the supported ionic liquid membranes was attained by transporting the corresponding ionic liquid through a Nylon membrane using Amicon UF as described in Hernández-Fernández et al [49].…”

New efficient laccase immobilization strategy using ionic liquids for biocatalysis and microbial fuel cells applications

“…Hernández‐Fernández et al . demonstrated that a polymer inclusion membrane (PIM) constructed from 30% polyvinyl chloride and 70% ionic liquid (IL), more specifically methyltrioctylammonium chloride, was efficient in the air cathode of an AC‐MFC.…”
