The bipolar membrane is a special function ion exchange membrane which hydrolyzes its intermediate layer under the action of an electric field to produce H+ and OH- ions. So everyone knows what is the functional principle of the bipolar membrane? as follows:
The bipolar membrane is a special ion exchange membrane, which is a composite membrane of yin and yang made of a combination of a positive membrane and an anion membrane. The film is characterized in that under the action of a direct current electric field, H2O between the composite layers of the anode and the cathode is dissociated into H+ and OH- and passed through the anion and the yang, respectively, as H+ and OH-ion sources. The bipolar membrane can be divided into a homogeneous bipolar membrane and a heterogeneous bipolar membrane according to the macroscopic membrane structure.
