More Information
Summary:Disclosed are diaphragm cloth for a water electrolyzer and a manufacturing method therefor. The diaphragm cloth adopts a woven fabric, non-woven cloth or a knitted fabric composed of polyphenylene sulfide fibers. The average pore size of the diaphragm cloth is smaller than 10 µm, and under the condition of a pressure at 3 KPa, the venting quality of the diaphragm cloth is 2 L/cm 2 /min or less. The diaphragm cloth for a water electrolyzer of the present invention has the features of high gas-tightness, good hydrophilicity and excellent ion permeability, also has low cost, safety, environmental protection and light weight; and the manufacturing method is rapid, and has the features of high efficiency, no pollution, simple operation and saving energy.
