Title:
LITHIUM CATION EXCHANGE MEMBRANE FOR WATER ELECTROLYSIS, AND WATER ELECTROLYSIS SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/030761
Kind Code:
A1
Abstract:
The present invention relates to a lithium cation exchange membrane, for water electrolysis, having high lithium cation conductivity, and a water electrolysis system using same, and a water electrolysis system using a lithium cation exchange membrane (LEM) for water electrolysis according to the present invention, comprising a hydrophilic polymer solution and a monomer solution having a sulfonic acid group, is an economically feasible water electrolysis system achieving lower costs than conventional proton exchange membrane (PEM) water electrolysis and a higher current density than alkali water electrolysis.
