    摘要: A bipolar membrane, usable for electrodialysis of aqueous electrolytes, comprises two ion exchange membranes, respectively anionic and cationic, juxtaposed along a common surface, wherein, along said common surface, a gel based on hydrated metal sulpate and/or sulphite, including less than 0.01 mol % of indium, cerium, manganese and copper sulphates gel, is formed.
