Abstract
The present invention describes a diaphragm comprising SPEEK for alkaline electrolysis with a first layer having micropores and a second layer of macroporous channels which start at the contact surface between the first and the second layer then extending and forming the outer surface of the second layer, where said macroporous channels increase in section and change direction as they approach said outer surface of the second layer, and where the walls of the macrochannels are in turn macroporous. The invention also describes a production method for producing the diaphragm comprising the use of the chemically induced phase separation (CIPS) technique, and its use in alkaline electrolysis and in electrolyzers.
