Problems solved by technology

MgH, which has been studied more at present 2 System as an example, there are the following problems in the actual use process: 1) Because the hydrolysis reaction is a violent exothermic reaction, the reaction rate of hydrogen production is difficult to control; 2) The reaction product Mg(OH) 2 will be coated in MgH 2 The surface of the particle prevents the further progress of the reaction and reduces the completeness of the reaction; 3) Since this type of chemical hydrogen production material is a solid material, it is easy to absorb moisture in the air or in a humid environment, and the amount of material is not easy to add accurately. The design of the reaction system Difficult 4) The reaction product Mg(OH)2 is easy to block the pipeline; these defects make the wide application of this method limited to a certain extent
