The power supply method of the energy self-sufficient water electrolysis fuel cell pure water system comprises the following steps: a step (step 310) of subjecting the water supplied to the water electrolysis unit to electrolysis to generate hydrogen and oxygen and supplying hydrogen gas to the energy generation unit by adjusting the pressure of the generated hydrogen gas; a step (step 320) of generating electric energy based on the hydrogen gas supplied to the energy generation unit to be used as a power source for purifying air; a step (step 330) of supplying the generated electric energy as power for purifying air by the energy storage unit; a step of discharging oxygen generated in the water electrolysis unit through the oxygen discharge port to purify air (step 341); and adjusting the indoor humidity by a humidifier that generates water vapor by one of an ultrasonic vibration method, a heating method, a natural evaporation method, and a nozzle method so as to spray or evaporate the received water (step 342).
In step 310, the water supplied to the water electrolysis unit is subjected to water electrolysis to generate hydrogen and oxygen, and the pressure of the generated hydrogen gas is adjusted to supply the hydrogen gas to the energy generation unit.
The water electrolysis unit performs water electrolysis treatment on the received water to generate hydrogen and oxygen, and adjusts the pressure of the generated hydrogen gas to supply the hydrogen gas to the energy generation unit.

The hydrogen storage part is used for storing the purified hydrogen gas.
In step 320, electrical energy is generated based on the hydrogen gas supplied to the energy generation portion to be used as a power source for purifying air.
The energy generation unit (in other words, the fuel cell) generates electric energy based on the hydrogen gas supplied to the energy generation unit to be used as a power source for purifying air. The energy generation unit generates electricity by electrochemically reacting hydrogen gas, which is generated by water electrolysis and then converted into high-purity pure hydrogen gas by a hydrogen purification step, with oxygen using a fuel cell.
In step 330, the generated electrical energy is supplied as power for purifying the air by the energy storage unit.
The battery management unit supplies the generated electric energy as the power for purifying the air without additional energy supply. The Energy storage unit, which includes a Battery Management System (BMS) and an Energy Storage System (ESS), stores the remaining Energy in the Battery 132 in a non-powered and drivable manner without additional supplementary Energy.
In step 341, the oxygen generated in the water electrolysis portion is discharged through the oxygen discharge port to purify the air.
The motor can drive the pure water by the power supplied from the energy storage unit. The oxygen discharge port purifies air by discharging oxygen generated in the water electrolysis portion. In this case, the oxygen generated in the water electrolysis unit is further dispersed and discharged by a fan (fan).
