Abstract
An energy-independent water-based pure air cleaning system using a water electrolytic-fuel cell is disclosed. The energy-independent water-based pure air cleaning system using a water electrolytic-fuel cell proposed by the present invention comprises: 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; and 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 a room.
