Hydrogen generation system, control device of hydrogen generation system and control method of hydrogen generation system

摘要

Problem to be solved: to improve the durability of the hydrogen generation system.Hydrogen generation system 1Electrolytic cellA main power supply 56 for supplying electric power to the electrolytic cellThe sub power supply part 58 independently supplies the power to the electrolytic cell 2 independently of the main power supply partVoltage of electrolytic cellA detecting portion 38 for detecting the potential of the oxygen generating electrode 12 or the potential of the hydrogen generating electrode 16, andA control unit 10 for controlling the supply of electric power to the electrolytic cell 2 based on the detection result of the detecting part 38 and.The control unit 10 controls the auxiliary power supply unit 58 to supply electric power to the electrolytic cell 2 when it is detected that the voltage or the potential has changed to a predetermined value during the operation stop of the hydrogen generation system 1 which is not supplied to the electrolysis vessel 2 by the power from the main power supply unit 56.Diagram
