Abstract:
1. A hydrogen generating apparatus comprising: an electrolyzer, filled with an aqueous electrolyte solution containing hydrogen ions; a first electrode, accommodated in the electrolyzer, submerged in the aqueous electrolyte solution, and generating electrons; a second electrode, accommodated in the electrolyzer, submerged in the aqueous electrolyte solution, and receiving the electrons to generate hydrogen; a switch, located between the first electrode and the second electrode; a flow rate meter, measuring an amount of hydrogen generation in the second electrode; and a switch controller, receiving a set value, comparing the amount of hydrogen generation measured by the flow rate meter with the set value, and controlling an on/off status of the switch, the switch controller generating and outputting a switch control signal turning the switch on and off, and the switch controller determining an on/off ratio of the switch within one cycle by varying a duty ratio of the switch control signal.
