       BACKGROUND OF THE PRESENT INVENTION 
       [0003]    Hydrogen is one of the most desirable energy in the 21st century. Hydrogen produces the most energy during combustion of the same weight of coal, gasoline and hydrogen, and the product of combustion of hydrogen is water without ash and waste gas, and therefore will not pollute the environment; while the main products of combustion of coal and oil are CO2 and SO2, which may cause greenhouse effect and acid rain. Reserves of oil and coal are limited, but hydrogen mainly exists in water, and the only product after combustion is also water, so that hydrogen can be generated continuously and will never run out. Hydrogen is widely distributed, and water is a large “warehouse” of hydrogen and contains 11% hydrogen. Soil contains about 1.5% hydrogen; and oil, coal, natural gas, animals, plants and the like all contain hydrogen. Hydrogen mainly exists in a form of a compound of water. about 70% of the Earth&#39;s surface is covered with water, and water storage capacity is large; therefore it can be said that hydrogen is “inexhaustible” energy. If hydrogen can be produced in a suitable way, then hydrogen will also be relatively cheap energy. 
         [0004]    At present, the methanol steam reforming technology is used to produce a gas mixture of H2 and CO2, then the gas mixture may be separated by a palladium membrane separator to obtain H2 and CO2 respectively. With reference to Chinese invention application 201310340475.0 (applicant: Shanghai Hydrogen Mobile Reformer Instrument. Co., Ltd), the patent discloses a methanol-water mixture hydrogen production system in which methanol and water steam in the reforming chamber of the reformer pass through catalysts at the temperature of 350-409° C and at the pressure condition of 1-5 MPa, and under the action of the catalysts, methanol cracking reaction and carbon monoxide shift reaction occur to generate hydrogen and carbon dioxide, and this is a gas-solid catalytic reaction system involving multiple components and multiple reactions, with reaction equations as follows: (1) CH3OH→CO+2H2; (2)H2O+CO→CO2+H2; and (3) CH3OH+H2O→CO2+3H2, H2 and CO2 generated from reactions are reformed, and then separated through the palladium membrane of a separation chamber to obtain high purity hydrogen.

The air inlet device  12  includes an air inlet channel  121  and a blower  122 . The blower  122  blows the external air first into the air inlet channel  121  and then into the flame tray  602  and the combustion chamber  503  of the reforming hydrogen production device  5 . 
         [0050]    As shown in  FIGS. 2, 7 and 21 , the methanol-water mixture reforming hydrogen production generator further includes a gas control system  10  provided on a transfer pipeline used for transferring hydrogen to the fuel cell  7 . The gas control system  10  includes a safety gas control pipe  101 , a safety solenoid valve  1032  and a safety air pressure sensor  103 . and the safety solenoid valve  1032  and the safety air pressure sensor  103  are mounted on the safety gas control pipe  101 . The safety gas control pipe  101  has a gas release hole matched with the safety solenoid valve  102 , and in a process that hydrogen passes through the safety gas control pipe  101 , if the safety air pressure sensor  103  senses that a hydrogen pressure is higher than an alert pressure, the safety solenoid valve  102  is controlled to open the gas release hole, to discharge hydrogen to the outside. At this time, the control mainboard  1  controls an alarm (not shown) to generate an alarm. The safety solenoid valve  102  can be powered by the rechargeable battery  201 , so as to ensure that the safe solenoid valve  102  is powered at any time. When the system has a problem in exhausting, the gas release hole of the safety gas control pipe  101  can be closed again by the safety solenoid valve  102 . Because of the setting of the gas control system  10 , problems of damage to devices such as the fuel cell  7  and the like by high hydrogen pressure caused by abnormality in the system are thereby avoided. Further, the gas control system  10  also includes a basic solenoid valve  104  and a basic air pressure sensor  105 . The basic solenoid valve  104  is used to open and close hydrogen delivery channel under normal conditions, The basic air pressure sensor  105  is used to sense hydrogen pressure under normal conditions.
