Title:
ELECTROLYTIC ELEMENT FOR ALKALINE WATER ELECTROLYSIS, AND ALKALINE WATER ELECTROLYSIS VESSEL
Document Type and Number:
WIPO Patent Application WO/2021/200372
Kind Code:
A1
Abstract:
This electrolytic element for alkaline water electrolysis comprises: an electroconductive partition wall having a first surface and a second surface; an anode for oxygen generation; a cathode for hydrogen generation; a first connection means for fixing the anode to the partition wall and electrically connecting the anode to the partition wall such that the anode faces the first surface of the partition wall with a first interval therebetween; an electroconductive elastic body which supports the cathode; and a cathode current collector which supports the elastic body. The cathode current collector is fixed to the partition wall so as to face the second surface of the partition wall with a second interval therebetween, and is electrically connected to the partition wall. The first connection means includes an electroconductive bolt having at least a shaft part, and the anode is detachably fixed to the partition wall via the electroconductive bolt.
