1. An energy-independent water-based pure air cleaning system using a water electrolytic-fuel cell, the energy-independent water-based pure air cleaning system being configured to perform air purification and to control humidity in a room without external power being supplied, the system comprising:
a water electrolysis unit that generates hydrogen and oxygen through a water electrolysis treatment using supplied water, and supplies hydrogen gas to an energy generating unit by adjusting the pressure of the generated hydrogen gas;
the energy generating unit that generates electrical energy on the basis of the hydrogen gas supplied for use as a power source for air purification;
an energy storage unit that does not need energy charging and supplies the generated electrical energy as power for air purification;
an oxygen exhaust port for discharging the oxygen generated in the water electrolysis unit for air purification in a room;
a humidifier that generates water vapor by spraying or evaporating the supplied water by any one of ultrasonic vibration, heating, natural evaporation, or nozzles to control the humidity in the room; and
a fan for simultaneously discharging the oxygen generated in the water electrolysis unit and the water vapor generated in the humidifier to the room for the air purification and the control of the humidity in the room;
wherein the oxygen exhaust port and the humidifier are disposed beneath the fan, and the oxygen from the oxygen exhaust port and the water vapor from the humidifier are discharged together through the fan;
wherein the water electrolysis unit comprises:
a solar panel for supplying electric power required for initial operation of the water electrolysis treatment using solar energy and utilizing the same as standby power;
a water electrolysis treatment unit for generating oxygen and hydrogen gas from filtered and purified water through hydrogen electrolysis using solar energy;
a gas control unit for adjusting the pressure of the hydrogen gas produced through the water electrolysis treatment and supplying the hydrogen gas;
a hydrogen refining unit for converting the generated hydrogen into clean hydrogen gas with high purity through a hydrogen refining process using an adsorbent; and
a hydrogen storage unit for storing the refined hydrogen gas;
wherein the energy generating unit produces electricity through an electrochemical reaction between oxygen and the clean hydrogen gas with high purity through the hydrogen refining process, by using a fuel cell; and
wherein the water electrolysis unit comprises:
an injection unit for receiving untreated water;
a filter disposed below the injection unit and at a side portion of the energy-independent water-based pure air cleaning system, for filtering and purifying the untreated water; and
an intake pump disposed on a bottom of the energy-independent water-based pure air cleaning system, for supplying the filtered and purified water to the water electrolysis treatment unit.
