NOVELTY - The hydrogen mixed gas supplying apparatus, comprises a ultrasonic atomizer or piezoelectric oscillate atomizer (5) for atomizing methanol mixed liquid into mixed liquid micro particles having average diameter of 2 mu m, a lead flow pipe (3) for the atomized mixed liquid micro particles to float and flow in the pipe, and a low temperature plasma heater (6) to heat dissolving the mixed liquid micro particles having entered into its heating area into hydrogen ions, hydroxide ions and the corresponding free radicals.    USE - Used as hydrogen mixed gas supplying apparatus.    ADVANTAGE - The supplying apparatus simply and economically supplies the hydrogen mixed gas with less consumption of electricity and without using nozzle and catalyst, and has reduced dimension and improved performance.    DETAILED DESCRIPTION - The hydrogen mixed gas supplying apparatus, comprises a ultrasonic atomizer or piezoelectric oscillate atomizer (5) for atomizing methanol mixed liquid into mixed liquid micro particles having average diameter of 2 mu m, a lead flow pipe (3) for the atomized mixed liquid micro particles to float and flow in the pipe, and a low temperature plasma heater (6) to heat dissolving the mixed liquid micro particles having entered into its heating area into hydrogen ions, hydroxide ions and the corresponding free radicals. The hydroxide ions and the corresponding free radicals are formed after the hydrogen ions immediately react with the uncraked mixed liquid micro particles such that the low temperature hydrogen mixed gas is then generated. The low temperature hydrogen mixed gas is generated after heat pyrolysis of methanol mixed liquid by the heating area of the plasma heater has a temperature of 15-25 degrees C, and is formed by a plug associating with a high voltage capacitor. An air inlet is formed at one end of the lead flow pipe, leads in air to fully mix and vaporize with mixed liquid micro particles and push the mixed liquid micro particles to flow towards the plasma heater. The lead flow pipe has a slow impact segment at the air inlet, and is formed by multiple components. The slow impact segment is a curved passage allowing mixed liquid micro particles to fully mix with the air lead from the air inlet. A reaction device (2) is installed at the lower end of the lead flow pipe, and is connected to a liquid storage tank (1) storing methanol mixed liquid via a lead pipe. An atomizer is installed at the lower end of the reaction device. A liquid level sensor (21) is installed at one end of the reaction device. The lead flow pipe is a lead flow component leading the vaporized and heated mixed liquid micro particles to the heating area of the plasma heater. A return outlet is formed at the lower end of the lead flow component to allow the mixed liquid micro particles that are not heated by the plasma heater to flow back to the reaction device, when the mixed liquid micro particles are turned into liquid form and then be atomized again for use. A control switch is installed at the liquid storage tank to make sure the tank not opened at random. The control switch of liquid storage tank is controlled by a chip card. The low temperature plasma heater uses a first coil and a second coil to match step-up transformer of low resistance and low inductance to the plug of no resistance as plasma output electrode for increase the current, a microfarad low voltage capacitor for storing energy power to provide electricity to the first coil for a short time, pulse width modulation for generate direct current to supply electricity to the demand of first coil reduced waste of electricity and so reduce the total amount of electricity consumption, high voltage capacitor of picofarad (pF) to nanofarad (nF) of 20-500 KV, and the plug of almost no resistance. The mixed liquid micro particles have an average diameter of 0.8-1.5 mu m. The atomizer is made with separate-excitation circuit. The hydrogen mixed gas supplying apparatus consists of a unit (4) to control the operation of the atomizer and the plasma heater.
