Bipolar ion exchange sheet and manufacturing method therefor

A method of manufacturing a bipolar ion exchange sheet, the method comprising:

• producing a cation adsorption sheet and an anion adsorption sheet;
• producing, respectively, a cation exchange membrane and an anion exchange membrane by coating a cation exchange coating solution on one surface of the cation adsorption sheet to form a cation exchange coating layer and by coating an anion exchange coating solution on one surface of the anion adsorption sheet to form an anion exchange coating layer;
• and
• bonding the cation exchange membrane to the anion exchange membrane such that the cation exchange coating layer is in contact with the anion exchange coating layer.
