Description

Technical fields:

[0001] This utility model relates to the field of hydrogen solid-state battery technology, and in particular to a hydrogen solid-state battery power generation device with an irregularly shaped hydrogen storage bottle. Background technology:

[0002] Currently, in the field of hydrogen solid-state batteries, hydrogen is generally stored by embedding hydrogen storage alloys within hydrogen storage cylinders. These alloys are metals that can absorb hydrogen and form chemical bonds with it. They can absorb and release hydrogen based on temperature changes. Unlike traditional physical hydrogen storage methods such as high-pressure cylinders or cryogenic liquefaction, hydrogen storage alloys store hydrogen as metal hydrides through combination with it, and can release the hydrogen under certain conditions. This method offers advantages such as large hydrogen storage capacity, low energy consumption, and ease of use, making storage and transportation more convenient and safer. Current hydrogen storage cylinders are generally regular cylindrical shapes, which limits their installation in different cavities. Furthermore, releasing hydrogen requires a separate heating device, consuming additional energy. In fuel cell vehicles, the fuel cell, lithium battery, and controller all generate a significant amount of heat during operation. If this heat could be utilized in conjunction with the hydrogen storage cylinder, it would save a considerable amount of energy. Currently, there is no good solution to the above problems.

[0003] In summary, the aforementioned problems with existing hydrogen storage cylinders during use have become urgent technical challenges that need to be addressed within the industry. Utility Model Content:

[0004] To overcome the shortcomings of existing technologies, this invention provides a hydrogen solid-state battery power generation device for irregularly shaped hydrogen storage bottles. This solves the problem of space constraints when installing hydrogen storage bottles in different cavities, and also solves the problem of the need for separate heating devices to consume more energy.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A hydrogen solid-state battery power generation device using an irregularly shaped hydrogen storage bottle includes an irregularly shaped hydrogen storage bottle containing a hydrogen storage alloy. The outlet of the irregularly shaped hydrogen storage bottle is connected to the hydrogen inlet of a fuel cell via a pipeline. A temperature sensor and a heater are installed at the outlet of the irregularly shaped hydrogen storage bottle. The fuel cell is connected to a lithium battery. The temperature sensor, heater, fuel cell, and lithium battery are each connected to a controller. The irregularly shaped hydrogen storage bottle is in contact with the fuel cell, lithium battery, and controller. The waste heat from the fuel cell, lithium battery, and controller is used to heat the irregularly shaped hydrogen storage bottle to release hydrogen.

[0007] The outer layer of the irregularly shaped hydrogen storage bottle is wrapped with an insulating film.

[0008] The outlet of the irregularly shaped hydrogen storage cylinder is connected to the hydrogen inlet of the fuel cell via a pipeline and a quick-connect fitting.

[0009] The fuel cell is connected to an exhaust pipe, which is connected to a heat exchanger. A fan is installed at the heat exchanger to evenly release heat to the irregularly shaped hydrogen storage cylinder.

[0010] A pressure sensor is installed at the outlet of the irregularly shaped hydrogen storage cylinder, and the pressure sensor is connected to the controller.

[0011] The present invention adopts the above solution and has the following advantages:

[0012] By using irregularly shaped hydrogen storage cylinders, the large contact area between the cylinders and fuel cells, lithium batteries, and controllers allows for full utilization of the waste heat from these components to heat the cylinders, ensuring uniform heating and enabling stable and continuous hydrogen release. This improves energy efficiency, and the irregular shape allows for excellent compatibility with battery boxes. Customized designs based on different cavities also save space.

[0014] Figure 2 This is a schematic diagram illustrating the principle of this utility model.

[0015] In the diagram, 1 is an irregularly shaped hydrogen storage cylinder, 2 is a fuel cell, 3 is a lithium battery, 4 is a controller, 5 is a temperature sensor, 6 is a heater, and 7 is a pressure sensor. Detailed implementation method:

[0016] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0017] like Figure 1-2 As shown, a hydrogen solid-state battery power generation device using an irregularly shaped hydrogen storage bottle includes an irregularly shaped hydrogen storage bottle 1. The irregularly shaped hydrogen storage bottle 1 is equipped with a hydrogen storage alloy. The outlet of the irregularly shaped hydrogen storage bottle 1 is connected to the hydrogen inlet of a fuel cell 2 via a pipeline. A temperature sensor 5 and a heater 6 are provided at the outlet of the irregularly shaped hydrogen storage bottle 1. The fuel cell 2 is connected to a lithium battery 3. The temperature sensor 5, heater 6, fuel cell 2, and lithium battery 3 are respectively connected to a controller 4. The irregularly shaped hydrogen storage bottle 1 is in contact with the fuel cell 2, lithium battery 3, and controller 4. The waste heat from the fuel cell 2, lithium battery 3, and controller 4 is used to heat the irregularly shaped hydrogen storage bottle 1 to release hydrogen.

[0018] The irregularly shaped hydrogen storage bottle 1 includes various shapes such as L-shaped, U-shaped, square, and ring-shaped. It has a large contact area with the fuel cell 2, lithium battery 3, and controller 4, making full use of the waste heat of the fuel cell 2, lithium battery 3, and controller 4 to heat the irregularly shaped hydrogen storage bottle 1, so that the bottle body is heated evenly, which can achieve stable and continuous hydrogen release, improve energy utilization, and the irregular structure can be well matched with the battery box. It can be customized according to different cavities to save space.

[0019] The outer layer of the irregularly shaped hydrogen storage bottle 1 is wrapped with an insulating film to keep it warm.

[0020] The outlet of the irregularly shaped hydrogen storage cylinder 1 is connected to the hydrogen inlet of the fuel cell 2 via a pipeline and a quick-connect fitting, reducing pipeline layout and leakage risks.

[0021] The fuel cell 2 is connected to an exhaust pipe, which is connected to a heat exchanger. A fan is installed at the heat exchanger. The high-temperature exhaust gas discharged from the fuel cell 2 can enter the heat exchanger, and the fan will evenly release the heat to the irregularly shaped hydrogen storage bottle 1, ensuring that the irregularly shaped hydrogen storage bottle 1 fully releases hydrogen.

[0022] Temperature sensor 5 can detect the hydrogen temperature in the irregularly shaped hydrogen storage bottle 1 in real time. When the temperature is lower than the hydrogen release temperature, temperature sensor 5 sends a signal to controller 4. Controller 4 controls heater 6 to heat the irregularly shaped hydrogen storage bottle 1 to reach the hydrogen release temperature, ensuring sufficient hydrogen release and improving driving range.

[0023] A pressure sensor 7 is installed at the outlet of the irregularly shaped hydrogen storage bottle 1. The pressure sensor 7 is connected to the controller 4. The pressure sensor 7 can detect the hydrogen pressure in the irregularly shaped hydrogen storage bottle 1. When the pressure is lower than the set value, it proves that the hydrogen in the irregularly shaped hydrogen storage bottle 1 has been released. At this time, the pressure sensor 7 will send a signal to the controller 4 to remind that a new irregularly shaped hydrogen storage bottle 1 needs to be replaced.

[0024] Working principle:

[0025] This invention can be applied to power generation equipment. When the irregularly shaped hydrogen storage bottle 1 is heated, the hydrogen inside enters the fuel cell 2 to generate electricity, or it can charge the lithium battery 3 for energy storage. It can also be applied to the automotive field. When the vehicle is accelerating or climbing and requires high power output, the lithium battery 3 and fuel cell 2 generate electricity simultaneously. The lithium battery 3 can discharge quickly to meet instantaneous power demands. When the vehicle is running stably or under low load, the system is powered by the fuel cell 2, which can simultaneously charge the lithium battery 3. The hybrid system of lithium battery 3 and fuel cell 2 can meet emergency and high power demands, making it more widely applicable. The irregularly shaped hydrogen storage bottle 1, working in conjunction with the fuel cell 2 and lithium battery 3, achieves comprehensive utilization of waste heat. It is also small in size, has a fast response, high efficiency, and long driving range, effectively solving the problems of short lifespan, large battery size, and low driving range of traditional lithium batteries.
