Abstract

The paper presents data on a new type of separation materials for alkaline water electrolyzers: a diaphragm synthesized by the phase inversion method and a multilayer microfilm membrane with zirconium hydroxide hydrogel as a hydrophilic filler. Experimental data are presented on their porosity, electrical conductivity, gas density, as well as the results of their tests as part of an alkaline electrolyzer battery in comparison with a porous diaphragm based on polysulfone with a hydrophilic filler (TiO2), synthesized by the traditional method of phase inversion. The advantages and disadvantages of new materials are determined, the ways of further research and development are determined.
