Title:
WATER ELECTROLYSIS SYSTEM AND ELECTRIC CURRENT CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/229652
Kind Code:
A1
Abstract:
The present invention reduces degradation of a water electrolysis cell in a system in which a plurality of water electrolysis cells are driven in parallel. This water electrolysis system includes a plurality of conversion circuits for converting first electric power generated by a solar power generation device into a plurality of second electric powers, a control circuit for at least controlling the number of driving conversion circuits from among the plurality of conversion circuits, and a plurality of water electrolysis cells for respectively receiving the plurality of second electric powers from the plurality of conversion circuits, the control circuit including a detector for detecting the occurrence of a variation exceeding a prescribed amount per prescribed time in the first electric power, and the control circuit increasing the number of driving conversion circuits when the detector detects the occurrence of said variation.
