Problems solved by technology

[0006] The above reaction is a liquid-solid exothermic reaction, and the reaction speed, that is, the rate of hydrogen production is related to the concentration of alkali, reaction temperature, and reaction area. To control this reaction and obtain a stable flow of hydrogen, an important measure is to control the area of ​​liquid-solid reaction and shift in time Removal of heat of reaction (control temperature). In a published patent (Patent No.: ZL02104279.9), the technology and device for producing hydrogen by the reaction of aluminum and sodium hydroxide aqueous solution have been announced. This technology uses aluminum powder as the reactant, liquid-solid The reaction area is difficult to control and cannot meet the requirements of obtaining a stable hydrogen flow rate; in patents 200710072342.4 and 201010293603.7, it is announced that the Kip generator principle is used to control the amount of water added to control the reaction rate, but due to changes in the reaction area and reactants As the reaction proceeds, the reaction rate is still difficult to control, and the system is very complicated, which is inconvenient to realize miniaturization. The inventor once designed a simple aluminum hydrolysis reaction hydrogen production device in the previous patent (200910153437.8). The device uses amalgam as a catalyst to produce hydrogen through aluminum hydrolysis. The device can precisely control the reaction temperature through a constant temperature water bath, but the system is still relatively complicated, and the amalgam is highly toxic, so it is strictly forbidden to be used in the preparation of hydrogen-rich water or hydrogen In health products such as ventilators
