BIPOLAR ALKALINE WATER ELECTROLYSIS UNIT AND ELECTROLYTIC CELL

摘要

A bipolar alkaline water electrolysis unit (12) which is built in an electrolytic cell (100) for the purpose of obtaining oxygen and hydrogen by electrolyzing an electrolysis solution that is composed of alkaline water. This bipolar alkaline water electrolysis unit (12) is provided with: a positive electrode (18) for the generation of oxygen; a negative electrode (19) for the generation of hydrogen; a conductive partition wall (22) for separating the positive electrode and the negative electrode from each other; and an annular outer frame (16) which surrounds the conductive partition wall (22). A passage part for a gas and the electrolysis solution is provided above the conductive partition wall (22) and/or the outer frame (16), while a passage part for the electrolysis solution is provided below the conductive partition wall (22) and/or the outer frame (16).
