Claims15
A bipolar membrane comprising a cation exchange membrane, an anion exchange membrane and an inorganic ion exchanger layer having a thickness of from 0.01 to 100 .mu.m present at the interface between the cation exchange membrane and the anion exchange membrane.
A bipolar membrane comprising a cation exchange membrane, an anion exchange membrane and a layer composed of inorganic ion exchanger particles and a matrix polymer present at the interface between the cation exchange membrane and the anion exchange membrane.
A bipolar membrane comprising a cation exchange layer, an anion exchange layer and an interface layer interposed between the cation exchange layer and the anion exchange layer, said interface layer having dispersed in an ion exchange polymer an inorganic ion exchanger having an electric charge opposite to the electric charge of said ion exchange polymer.
A bipolar membrane comprising a cation exchange membrane, an anion exchange membrane and an inorganic ion exchanger layer interposed between the cation and anion exchange membranes, said inorganic ion exchanger layer having been formed by coating a metal alkoxide-containing solution having particles of an inorganic ion exchanger dispersed therein, followed by baking.
