Transfer processes in porous diaphragms and ion-exchange membranes for hydrogen production in electrochemical reactor with reduced energy consumption

Abstract

This paper presents the results of measuring the main physicochemical parameters of diaphragm materials (porous polypropylene, asbestos, mipor, polypropylene, nylon and chlorine fabrics) and the MA-40 anion-exchange membrane. These materials can be used to separate electrode chambers in an electrochemical reactor for producing hydrogen with reduced energy consumption. The values of materials (diffusion and migration) flows in the cathode and anode chambers are described and calculated for the use of porous separating partitions and an anion-exchange membrane. It has been experimentally proven that for woven separating materials, filtration transfer of substances is possible when the pressure in the electrode chambers changes. The complex of obtained results of the studied separating partitions (diaphragms and anion-exchange membrane) clearly indicates the feasibility of using an anion-exchange membrane in an electrochemical reactor with a soluble iron anode to produce hydrogen with reduced energy costs.
