[0002] In the field of portable power supplies, especially in hydrogen fuel power supply equipment based on the principle of powder hydrogen production, the reactor is mainly used to provide a reaction place for hydrogen production raw materials. In particular, in hydrogen fuel power supply equipment using aluminum-based, magnesium-based and other metal powders as hydrogen production raw materials, the reactor needs to take into account the characteristics of temperature resistance, pressure resistance, corrosion resistance and non-reaction with hydrogen.

[0003] Currently, in powdered hydrogen fuel cell equipment, hydrogen-containing metal powder is typically pre-installed in a reactor. When hydrogen production is needed, water is simply added to the reactor for immediate use. To achieve this, the reactor design often incorporates multiple external ports for water injection, exhaust, hydrogen output, and pressure relief.

[0005] The above-mentioned hydrogen production device arranges the spray water pipe and the hydrogen outlet at the upper part of the reactor. During the hydrogen production process, the water sprayed from the spray water pipe will hinder the discharge of hydrogen, thereby affecting the hydrogen production efficiency. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] A typical implementation of the present invention is as follows: Figure 1 As shown, a fuel power reactor includes a reactor cover 1 and a reactor tank 7. The reactor cover 1 and the reactor tank 7 are connected by threads. A sealing ring is provided at the connection between the reactor cover 1 and the reactor tank 7 to ensure the airtightness of the entire reactor.

[0026] A quick connector 2 and a pressure relief valve 3 are provided on the side wall of the reactor cover 1, wherein the quick connector 2 is used to connect the gas line, and the pressure safety in the reactor is ensured by the pressure relief valve 3. When the pressure in the reactor exceeds the set pressure, the pressure relief valve 3 automatically opens to ensure the safety of the device. The pressure relief valve 3 and the quick connector 2 are connected to the reactor cover 1 with sealing rings to ensure the sealing of the entire reactor.

[0027] A filter screen 4 is also provided inside the reactor cover 1. The filter screen 4 is fixed to the bottom end of the reactor cover 1 by bolts. By providing the filter screen 4 inside the reactor cover 1, the generated hydrogen is filtered and impurities such as reaction products are blocked from entering the gas path, thereby ensuring the purity of the generated hydrogen.

[0028] like Figure 2 As shown, a boss 8 is provided on the bottom surface of the interior of the reactor pot 7, and a water injection port 10 is opened at the axis of the boss 8, so as to realize the communication between the interior of the reactor pot 7 and the outside, so as to facilitate water to flow into the interior of the reactor pot 7 from the water injection port 10. A thread is provided on the outer surface of the top of the boss 8, and the boss 8 is connected to the reactor inner tube 5 through the thread. The reactor inner tube 5 is hollow and has multiple groups of water injection holes 11 of different heights on the outer surface. After water enters from the water injection port 10, it flows into the inner cavity of the reactor pot 7 through the water injection holes 11 on the reactor inner tube 5. Multiple groups of water injection holes 11 of different heights are set up. The purpose is that when the reaction reaches a certain stage, the aluminum hydroxide generated by the reaction will expand to a certain height. If only one group of water injection holes is opened, the water injection holes will be blocked, thereby causing the reaction to be unable to continue. Multiple groups of main water holes of different heights ensure that the water injection holes will not be blocked by the reaction products in the second half of the reaction.

[0029] like Figure 3As shown, a plug 6 is provided in the hollow area at the connection between the inner tube 5 of the reactor and the boss 8, and a spring is provided between the plug 6 and the bottom of the inner tube 5 of the reactor. The plug 6 is fixed at the connection between the inner tube 5 of the reactor and the boss 8 by the spring. The water injection port 10 is sealed by the plug 6. A sealing ring is provided on the plug 6 to ensure the air tightness of the reactor device before and after the reaction.

[0030] A thread is provided on the inner surface of the bottom end of the water injection port 10, and the bottom end of the water injection port 10 is connected to the base 9 through a thread. A through hole 12 is opened at the axis of the base 9. When the base 9 is screwed into the water injection port 10, the base 9 lifts the plug 6, and the plug 6 compresses the spring and moves to the side of the reactor inner tube 5, so that the plug 6 no longer blocks the water injection port 10, and the through hole 12 on the base 9 is connected to the reactor inner tube 5.

[0031] A sealing ring is provided at the connection between the base 9 and the water injection port 10 to ensure the sealing between the base 9 and the water injection port 10.

[0032] A hose connector 13 is provided at one end of the base 9 away from the water inlet 10. When in use, the hose connector 13 is connected to an external water pump through a hose, thereby supplying water to the reactor.

[0033] How it works

[0034] Before starting the aluminum-hydrogen fuel cell system, aluminum powder is loaded into the reactor tank 7. The reactor lid 1 is then tightened onto the reactor tank 7. The reactor tank 7 is then connected to the base 9 to complete the water connection. The quick connector 2 on the reactor lid 1 is then connected to the corresponding quick connector on the gas line to complete the gas connection. During operation, water flows from the base into the reactor inner tube 5 and into the reactor tank 7 through the water injection hole 11 on the reactor inner tube 5. The water then reacts with the aluminum powder in the reactor tank 7 to generate hydrogen. The generated hydrogen is filtered through the filter 4, then enters the gas line of the aluminum-hydrogen fuel cell system through the quick connector 2, and ultimately enters the fuel cell stack.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
