Polysulfone-Based Polymeric Diaphragms for Electrochemical Devices with Alkaline Electrolyte

Two kinds of diaphragm materials based on polysulfone with impregnated particles of a hydrophilic filler for alkaline water electrolyzers are suggested: nonwoven diaphragm materials produced by the electrospinning method and film diaphragms fabricated by the phase-inversion method. Their physicochem...

Description
Summary:Two kinds of diaphragm materials based on polysulfone with impregnated particles of a hydrophilic filler for alkaline water electrolyzers are suggested: nonwoven diaphragm materials produced by the electrospinning method and film diaphragms fabricated by the phase-inversion method. Their physicochemical characteristics were compared. It was found that film diaphragms are preferable for water electrolyzers operating under high pressure, for which high requirements are imposed on the purity of the gases being generated.
