METHOD FOR MANUFACTURING DIAPHRAGM FOR ALKALINE WATER ELECTROLYSIS, AND DIAPHRAGM FOR ALKALINE WATER ELECTROLYSIS
Document Type and Number:
WIPO Patent Application WO/2015/030025
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a diaphragm for alkaline water electrolysis, which has excellent ion permeability and chemical resistance and hardly undergoes the adhesion of a gas, which is generated at an electrode upon the electrolysis, onto the surface thereof.
The method for manufacturing a diaphragm for alkaline water electrolysis according to the present invention comprises: a step of preparing a resin composition comprising an epoxy resin, a curing agent and a porogen; and a step of producing a resin sheet using the resin composition. In one embodiment, the method for manufacturing a diaphragm for alkaline water electrolysis according to the present invention additionally involves a step of removing the porogen from the resin sheet.
