Abstract
An alkaline water electrolysis diaphragm includes: a polymer porous layer containing at least one polymer compound selected from polyether sulfone having a contact angle of 20 to 90° and polysulfone having the contact angle of 20 to 90°; and an organic fiber fabric layer coupled to the polymer porous layer. The polyether sulfone having the contact angle of 20 to 90° is at least one polymer compound selected from the group made of polyether sulfone, hydrophilic polyether sulfone, cationic polyether sulfone, and cationic hydrophilic polyether sulfone. The polysulfone having the contact angle of 20 to 90° is at least one polymer compound selected from the group made of polysulfone, hydrophilic polysulfone, cationic polysulfone, and cationic hydrophilic polysulfone.
