Title:

DIAPHRAGM FOR ALKALINE WATER ELECTROLYSIS, METHOD FOR PRODUCING SAME, AND ALKALINE WATER ELECTROLYSIS APPARATUS

Document Type and Number:

WIPO Patent Application WO/2015/093047

Kind Code:

A1

Abstract:

A diaphragm (90) for alkaline water electrolysis is configured of: a polymer porous layer (91) which contains at least one polymer compound that is selected from among polyethersulfones and polysulfones, each having a contact angle of 20-90°; and an organic fiber fabric layer (92) that is bonded to the polymer porous layer (91). The polyethersulfones having a contact angle of 20-90° are one or more polymer compounds that are selected from the group consisting of polyethersulfones, hydrophilic polyethersulfones, cationic polyethersulfones and cationic hydrophilic polyethersulfones. The polysulfones having a contact angle of 20-90° are one or more polymer compounds that are selected from the group consisting of polysulfones, hydrophilic polysulfones, cationic polysulfones and cationic hydrophilic polysulfones.
