Abstract

A procedure using phase inversion was suggested for synthesizing a polymer composite diaphragm material based on a polysulfone for water electrolysis with alkaline electrolyte. The diaphragms prepared using this material consist of a matrix of an alkali-resistant polymer with impregnated hydrophilic filler particles. They allow the power efficiency of water electrolyzers to be considerably enhanced relative to the known Russian and imported analogs.
