Description

technical field [0001] The invention relates to the technical field of water electrolysis hydrogen production equipment, in particular to a voltage monitoring system and a voltage acquisition method of an electrolytic cell cell of water electrolysis hydrogen production equipment. Background technique [0002] The core device in the water electrolysis hydrogen production equipment is the electrolyzer. Whether the voltage of the electrolyzer cell is normal or not reflects the working state of the electrolyzer, which represents the performance of the membrane and the active state of the anode and cathode of the unit cell. If the voltage of the cell is too high, it may cause In the event of an explosion, the abnormal drop in cell voltage may cause a short circuit and cause sparks. Real-time monitoring of the cell voltage in the electrolytic cell is of great reference significance for the safe operation of the equipment and energy saving. [0003] Measuring the chamber voltage ha...
