NOVELTY - Processing device comprises e.g. gas generating chambers for generating hydrogen gas by electrolysis of distilled water; a first gas storage tank having cooling coil installed on the gas generating chambers for cooling hydrogen gas; a second gas storage tank formed with a bubble generator installed on the first gas storage tank for collecting pure hydrogen gas; a spray nozzle provided with a pressure control unit installed on the second gas storage tank for spraying the collected pure hydrogen gas; and a refrigeration unit having a cooling coil for lowering the temperature of distilled water.    USE - Used as processing device.    ADVANTAGE - The device has compact size, produces desired amount of hydrogen gas, protects user from direct expose to hydrogen gas, removes foreign substances which are harmful to human body, prevents foreign substances from sticking during electrolysis process, uses ceramic gasket instead of rubber gasket, optimizes hydrogen gas production yield, and provides hydrogen which treat inflammation and improve wrinkles and follicles.    DETAILED DESCRIPTION - Processing device comprises a hydrogen generator; first, second and third gas generating chambers for generating hydrogen gas by electrolysis of distilled water; a first gas storage tank (50) having cooling coil installed on the gas generating chambers for cooling hydrogen gas generated from the gas generating chambers; a second gas storage tank (70) equipped with a bubble generator (72) installed on the first gas storage tank for collecting pure hydrogen gas discharged from distilled water; a spray nozzle (110) provided with a pressure control unit installed on the second gas storage tank for spraying the collected pure hydrogen gas into skin or lesion; a refrigeration unit (90) for lowering the temperature of distilled water and embedded with a cooling coil for supplying distilled water into the refrigeration unit and installed on the first gas storage tank; a distilled water supply unit filled with distilled water and installed on the first gas storage tank for constantly supplying distilled water into the gas generating chambers through a pump and a distribution header; and a control unit installed on the first and second gas storage tanks for controlling the supply of distilled water into the gas generating chambers and hydrogen gas supplied from the gas generating chambers. The outer periphery of a side plate of the gas generating chambers are provided with a multiple through-holes arranged at an interval. The outer periphery of the ceramic gasket and multiple cell plates is formed with multiple through-holes arranged at an interval. The side plate, the cell plate and the ceramic gasket of the gas generating chambers are interconnected by communicating with the through holes and multiple insulation coated tubes.
