Bipolar membrane
Function:
A bipolar membrane is a new type of ion exchange composite membrane, which is usually composed of a cation exchange layer (N-type membrane), an intermediate interface hydrophilic layer (catalytic layer), and an anion exchange layer (P-type membrane). Under the action of a DC electric field, the water in the intermediate interface layer dissociates, and hydrogen ions and hydroxide ions are obtained on both sides of the membrane.
