Anionic catalyst binders based on trimethylamine-quaternized poly(2,6-dimethyl-1,4-phenylene oxide) for alkaline electrolyzers
Original language description
Poly(2,6-dimethyl-1,4-phenylene oxide) (FPO) was brominated under the conditions of radical mechanism and subsequently quaternized with trimethylamine. Flat membranes were prepared by casting quaternized PRO (qPPO) dissolved in ethanol or ethanol/dimethylformamide mixture on a Teflon plate Followed by solvent evaporation. The membranes were characterized by their degree of swelling in water, ion exchange capacities (IEC) and ionic conductivities, qPPO with a degree of quaternization of 25.5 mol% and with anionic conductivities of 10.09 S/m and 12.34 S/m (at 50 degrees C and 70 degrees C, respectively) was tested as an anion-conductive polymer binder in a single cell alkaline laboratory electrolyzer in which the anode and cathode compartments were separated with a heterogeneous anion selective membrane. The cathode contained Pt/carbon catalyst bonded with qPPO so that Pt/qPPO weight ratio was 85/15. The anode contained NiCo2O4 spinel catalyst which was bonded either with VP (spinel/qPPO
