At the same time, high temperature will be generated when the heating plate 11 is started. At this time, the heating plate 11 is inside the water tank 10. When the heating plate 11 is started, it will heat the liquid in the water tank 10. At the same time, the circulation pump 13 is started. When the circulation pump 13 is started, the heated liquid in the water tank 10 will be input into the circulation pipe 9 through the heating pipe 12.

At this time, the water in the reaction shell 2 absorbs the heat energy on the surface of the reaction shell 2 to heat the reaction water. The decomposition between the water and the hydrogen generator 3 is accelerated by heating, and the production efficiency of hydrogen is improved. At this time, the transport pipe 5 in the heating hole 7 also absorbs the temperature of the heat transfer plate 6. Because hydrogen is transported in the transport pipe 5, the hydrogen in the transport pipe 5 will be heated. By heating the hydrogen, the kinetic energy of the hydrogen molecules is increased, making it easier for them to react chemically. By heating the hydrogen, the decomposition and generation process of hydrogen can be promoted, the reaction rate can be increased, and the speed of hydrogen production can be accelerated.
