Title:
WATER ELECTROLYSIS DEVICE AND WATER ELECTROLYSIS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/117096
Kind Code:
A1
Abstract:
This water electrolysis device comprises: a plurality of water electrolysis cells that are connected in series; a plurality of detection circuits that are respectively provided to the plurality of water electrolysis cells, and that each detect the current flowing in a by-pass circuit connected in parallel to the corresponding water electrolysis cell; and a signal output circuit that outputs a signal when the current value of the current detected by at least one detection circuit among the plurality of detection circuits exceeds a threshold.
