Description

Technical Field

[0001] The utility model relates to the field of hydrogen energy power sources, in particular to a hydrogen energy mobile emergency power source. Background Art

[0002] Hydrogen mobile emergency power supply is a portable power supply device based on hydrogen energy technology, which is mainly used in occasions where temporary or emergency power is needed. In hydrogen mobile emergency power supply, there will be hydrogen fuel cells, which will react with hydrogen and oxygen (usually obtained from the air) to produce electricity and water without producing harmful emissions, so it is very environmentally friendly.

[0003] The operating temperature of hydrogen fuel cells is usually between 50℃ and 100℃. Generally speaking, the higher the operating temperature of the battery, the faster the chemical reaction rate, and thus the greater the current generated, and more water will be produced. For hydrogen fuel cells with proton exchange membrane as the electrolyte, this membrane only allows protons to pass through, thereby preventing direct contact between electrons and hydrogen and oxygen, improving the safety and efficiency of the battery. However, as the reaction accelerates and the current increases, excessive water may cause the electrolyte membrane to be flooded, affecting the transfer of ions and affecting the power supply of the hydrogen mobile emergency power supply. Utility Model Content

[0004] The utility model aims to provide a hydrogen-powered mobile emergency power supply, which effectively solves the problem that excessive water in a hydrogen fuel cell may cause flooding of the electrolyte membrane, affect the transfer of ions, and thus cause a decrease in power supply capacity.

[0005] The technical solution of the utility model is as follows:

[0006] A hydrogen-powered mobile emergency power supply comprises a battery body, wherein a left end plate and a right end plate which are snap-fitted and sealed together are movably arranged in the battery body, a hydrogen inlet is arranged on one side of the left end plate, an oxygen inlet is arranged on one side of the right end plate, a proton exchange membrane is symmetrically arranged inside the right end plate, a sealing plate is arranged on the periphery of the proton exchange membrane, a water flow plate is arranged at the inner bottom end of the right end plate and below the sealing plate, a water flow slide is arranged on the top of the water flow plate, the water flow slide is inclined, a through hole is arranged on the right end plate near the lowest point of the water flow slide, a water receiving pipe is arranged in the through hole, and a collecting tank is arranged at the other end of the water receiving pipe.

[0007] Furthermore, the thickness of the right end plate is greater than that of the left end plate, and a water flow channel is provided between the two proton exchange membranes.

[0008] Furthermore, the sealing plate is located inside the right end plate, and the outer wall of the sealing plate is sealed and connected to the inner wall of the right end plate.

[0009] Furthermore, the length of the water flow plate is consistent with the length of the sealing plate, and the vertical section of the water flow slide is semicircular.

[0010] Furthermore, a water absorption layer is provided between the tops of the two proton exchange membranes, and the water absorption layer extends into the water flow channel.

[0011] Furthermore, a water pipe is provided at the bottom of the side wall of the collecting tank, and the water pipe extends along the outer wall of the right end plate to the top of the right end plate. A fixing plate is provided between the water pipe and the outer wall of the right end plate, and a water pump is provided on the water pipe.

[0012] Furthermore, the water delivery pipe is provided with a plurality of evenly distributed water delivery cores at a position above the right end plate, and the water delivery cores extend into the water absorption layer.

[0013] The advantages of the utility model are:

[0014] 1. The utility model sets a water flow plate on the inner bottom wall of the right end plate. The water flow plate and the sealing plate fit each other. When oxygen enters the right end plate and combines with protons passing through the electrolyte and electrons from the anode, the generated water will fall downward into the water flow slide. The water flow slide is inclined so that water flows into the collection tank through the water receiving pipe, thereby realizing water collection and effectively preventing excessive water from flooding the proton exchange membrane and slowing down ion transfer under high-speed chemical reactions.

[0015] 2. The utility model provides a water delivery pipe on the collection tank. The water pump delivers the water in the collection tank to the upper position of the right end plate. The water delivery pipe is provided with water delivery cores evenly distributed. The water delivery cores will introduce water into the water absorption layer. The water will slowly pass through the water absorption layer and flow on the proton exchange membrane. When the proton exchange membrane is in a wet state, it not only helps water molecules to help the transfer of protons in the membrane, but also realizes the collection and reuse of water in the product.

[0016] 3. The utility model provides two layers of proton exchange membranes inside the right end plate. Compared with the one-layer method, the two-layer proton exchange membrane can be used as a safety mechanism. For example, when one layer of the membrane is damaged or fails, the other layer of the membrane can still maintain the proton conduction function, preventing the battery performance from dropping sharply or a safety accident from occurring, thereby improving safety.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figures 1 to 5 As shown, the utility model provides a hydrogen energy mobile emergency power supply, which includes a battery body 1, in which a left end plate 2 and a right end plate 3 that are snap-fitted and sealed together are movably arranged, a hydrogen inlet 4 is arranged on one side of the left end plate 2, an oxygen inlet 5 is arranged on one side of the right end plate 3, and a proton exchange membrane 6 is symmetrically arranged inside the right end plate 3. The arrangement of the two layers of proton exchange membranes 6 can be used as a safety mechanism. For example, when one layer of the membrane is damaged or fails, the other layer of the membrane can still maintain the proton conduction function, thereby preventing a sharp decline in battery performance or a safety accident, thereby improving safety.

[0025] A sealing plate 7 is provided on the periphery of the proton exchange membrane 6. The sealing plate 7 is located inside the right end plate 3, and the outer wall of the sealing plate 7 is sealed and connected to the inner wall of the right end plate 3. The sealing plate 7 is fixedly connected to the four side walls of the proton exchange membrane 6 so that after hydrogen and oxygen are introduced separately, no crosstalk occurs.

[0026] A water flow plate 8 is provided at the inner bottom of the right end plate 3 and below the sealing plate 7. The water flow plate 8 is fixedly connected to the right end plate 3. The proton exchange membrane 6 is located just above the water flow plate 8. A water flow slide 9 is provided on the top of the water flow plate 8. The water after chemical reaction with oxygen can fall onto the water flow slide 9 through the provided water flow slide 9.

[0027] The water flow slide 9 is inclined so that water can flow downward better on the water flow slide 9, thereby preventing excessive product water from flooding the proton exchange membrane 6 and affecting ion transfer.

[0028] A through hole 10 is provided at the lowest point of the right end plate 3 near the water flow slide 9. A water receiving pipe 11 is provided in the through hole 10. A collecting tank 12 is provided at the other end of the water receiving pipe 11. The collecting tank 12 is fixed inside the battery body 1 so that the water of the product can be collected.

[0029] The thickness of the right end plate 3 is greater than that of the left end plate 2 . A water flow channel 13 is provided between the two proton exchange membranes 6 . The water flow channel 13 allows the water in the collection tank 12 to slowly flow on the proton exchange membrane 6 to keep the proton exchange membrane 6 moist.

[0030] The length of the water flow plate 8 is consistent with that of the sealing plate 7, so that when water flows on the water flow slide 9, it can completely enter the through hole 10 and finally enter the water receiving pipe 11, avoiding water from flowing into the right end plate 3. The vertical section of the water flow slide 9 is semicircular.

[0031] A water absorption layer 14 is provided between the tops of the two proton exchange membranes 6. The water absorption layer 14 extends into the water flow channel 13. The two side walls of the water absorption layer 14 are respectively in contact with the membrane walls of the proton exchange membrane 6, so that the water in the water absorption layer 14 can flow slowly on the proton exchange membrane 6 when flowing out.

[0032] A water pipe 15 is provided at the bottom of the side wall of the collecting tank 12. The water pipe 15 extends along the outer wall of the right end plate 3 to the top of the right end plate 3. A fixing plate 16 is provided between the water pipe 15 and the outer wall of the right end plate 3. A water pump 17 is provided on the water pipe 15. The water in the collecting tank 12 is pumped out by the water pump 17 and transported to the top of the right end plate 3 through the water pipe 15.

[0033] The water pipe 15 is located above the right end plate 3 and is provided with a plurality of evenly distributed water cores 18 . The water cores 18 extend into the water absorbing layer 14 , so that water in the water pipe 15 can enter the water absorbing layer 14 through the water cores 18 .

[0034] Detailed usage and effects of the above embodiments:

[0035] During the reaction, hydrogen is introduced into the interior of the left end plate 2 through the hydrogen inlet 4 on the left end plate 2, and oxygen is introduced into the interior of the right end plate 3 through the oxygen inlet 5 on the right end plate 3. Hydrogen is decomposed into protons and electrons under the action of the catalyst. The protons are transferred to the cathode through the proton exchange membrane 6, and the electrons form an electric current through the external circuit. Oxygen combines with protons and electrons to generate water. The water will fall along the proton exchange membrane 6 onto the water flow slide 9 on the water flow plate 8, and enter the water receiving pipe 11 through the through hole 10 along the water flow slide 9, and finally enter the collection tank 12, effectively preventing excessive water from submerging the proton exchange membrane 6.

[0036] Start the water pump 17, which will transport the water in the collection tank 12 in the water pipe 15 and transport it to the top of the right end plate 3. The water core 18 will introduce the water in the water pipe 15 into the water absorption layer 14, so that the water in the water absorption layer 14 can slowly flow down on the proton exchange membrane 6. When the proton exchange membrane 6 is in a wet state, the water pump 17 will no longer be used to transport water, so as to keep the proton exchange membrane 6 wet and allow water molecules to help the transfer of protons in the membrane.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
