Water electrolysis device for producing hydrogen and oxygen through separation by using bipolar capacitor to replace ion diaphragm

The invention discloses a water electrolysis device for producing hydrogen and oxygen through separation by using a bipolar capacitor to replace an ion diaphragm. The device comprises a constant-current voltage-stabilized power supply, an electrolytic bath and a bipolar capacitor polar plate; the bipolar capacitor polar plate, replacing the ion diaphragm,is vertically arranged in the middle of the electrolytic bath; electrolyte in the electrolytic bath is completely separated into two parts, and a hydrogen evolution cathode chamber and an oxygen evolution anode chamber are formed; a hydrogen production electrode and an oxygen production electrode are respectively arranged in the hydrogen evolution cathode chamber and the oxygen evolution anode chamber; and the constant-current stabilized power supply is connected to the hydrogen production electrode and the oxygen production electrode in the electrolytic bath. The bipolar capacitor is introduced into the water electrolysis device, hydrogen production and oxyg
