Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen storage equipment, and in particular to a solid-state hydrogen pool unit, an operating system and a heat exchange system. Background Art

[0002] As a renewable secondary energy source, hydrogen energy has attracted widespread attention due to its pollution-free and environmentally friendly characteristics during conversion and utilization. Especially in the automotive field, hydrogen energy is regarded as a potential energy carrier to replace traditional fossil fuels and is widely used in hydrogen fuel cell power systems. In a hydrogen fuel cell engine system, hydrogen and oxygen react under the action of an electrochemical catalyst to release electrical energy and thermal energy. Electric energy drives the vehicle's power system, while thermal energy is discharged through an external heat sink. Due to the low density of hydrogen, its storage density is not high. Therefore, in order to achieve the long-range goal of hydrogen fuel cell vehicles, the working pressure of the hydrogen storage system needs to be continuously increased, which also brings about the problem of energy consumption in the hydrogen storage process. Even if hydrogen can be compressed to 35MPa or 70MPa, the hydrogen storage density is still difficult to meet the long-range requirements of commercial heavy trucks.

[0003] In order to improve the hydrogen storage density, metal hydrogen storage is used to achieve high-density hydrogen storage in the prior art. Metal hydrogen storage materials are often manufactured in the form of powder, cube and other regular and irregular polyhedrons to realize solid hydrogen storage unit manufacturing. When storing hydrogen in bulk powder form in bottles, it is difficult to accurately control the reaction rate during the hydrogen hydrolysis release process, and the hydrogen storage cylinder is easily damaged under high-pressure operation; during the hydrogen release process of irregular polyhedron hydrogen storage monomers such as spheres, it is difficult to control the hydrogen release rate due to the large change in the contact area with the liquid; in both implementation methods, after the solid hydrogen storage material contacts the liquid, the heat conduction efficiency in the hydrogen release process is low, and the huge reaction heat cannot be conducted and dissipated, which easily causes excessive local temperature and brings safety hazards.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Solid-state hydrogen storage materials are high hydrogen storage density hydrogen storage materials, which can be divided into reversible hydrogen storage materials and irreversible hydrogen storage materials, and can also be divided into metal hydrogen storage materials and non-metal hydrogen storage materials, mainly high hydrogen storage density hydrogen storage materials that can release hydrogen by adding water, such as metal materials (magnesium, calcium, aluminum, etc.), hydrogen storage alloys, inorganic ionic compound hydrogen storage materials, carbonaceous hydrogen storage materials, metal organic skeleton compound hydrogen storage materials, etc. Among them, hydrogen storage alloys include binary systems, ternary systems and multi-element systems, such as lithium hydride, sodium hydride, potassium hydride, magnesium hydride, calcium hydride, aluminum hydride, etc.; while inorganic ionic compound hydrogen storage materials mainly include coordinated hydrides and amino compounds, such as sodium aluminum hydride, lithium borohydride and ammonia borane, which are all hydrogen storage materials with relatively high hydrogen storage density. The materials described in the patent of this invention include composite materials mixed with various materials, and typical materials such as layered combinations of materials with different temperature gradients during hydrogen release, etc. are materials composed of similar mixing methods.

[0034] Lithium batteries store electricity as a secondary energy source, while solid-state hydrogen pools store hydrogen as a secondary energy source. The energy storage density of solid-state hydrogen pools can be more than 10 times that of lithium batteries. If a fuel cell is used to convert it into electricity, the efficiency of the fuel cell is calculated according to the conventional 50%. The energy density of the solid-state hydrogen pool after the hydrogen energy is converted into electricity is also close to 10 times that of a lithium battery. The current industry's selection of hydrogen storage materials requires that they must have a high degree of reversibility (i.e., a reversible process of repeatedly absorbing and releasing hydrogen), and the number of reversible cycles (also known as cycle life) must meet a certain number of times, for example, the number of cycles must exceed 5,000 times. Although many high-density hydrogen storage materials have been discovered, stable high-density hydrogen storage materials require high temperatures to release hydrogen, and unstable high-density hydrogen storage materials react too quickly and are difficult to control.

[0035] The embodiments of the present application provide a solid-state hydrogen pool unit, an operating system and a heat exchange system, which solve the problems in the prior art that it is difficult to accurately control the reaction rate during the hydrolysis and release process of hydrogen when storing hydrogen in bottles in the form of bulk powder, and the hydrogen storage bottles are easily damaged under high-pressure operation; during the hydrogen release process of irregular polyhedron hydrogen storage monomers such as spheres, it is difficult to control the hydrogen release rate due to the large change in the contact area with the liquid; in both implementation methods, after the solid-state hydrogen storage material contacts the liquid, the heat conduction efficiency in the hydrogen release process is low, and the huge reaction heat cannot be conducted and dissipated, which can easily cause the local temperature to be too high, posing a safety hazard. The present application stacks multiple groups of solid-state hydrogen pools side by side to form a tubular solid-state hydrogen pool unit, which effectively improves the storage density of the hydrogen storage material. The contact area between the solid hydrogen storage material and the reaction liquid is controllable, so that the release rate of hydrogen can be accurately controlled, and the rapid conduction and dissipation of heat can be achieved through the combination of a metal support frame and an inner cooling cavity of the interlayer; the solid-state hydrogen pool unit cooperates with a hydrogen release subsystem and a solid-state hydrogen pool heat exchange system to realize external quick-change replacement of the solid-state hydrogen pool unit, provide system-level signal interaction to the outside, provide heat exchange energy to the outside, and quickly discharge the tail liquid, etc., to ensure that the solid-state hydrogen pool unit and its related systems can operate safely, reliably and efficiently under various working conditions.

[0036] Please refer to the following examples for details:

[0037] Reference Figure 1-Figure 2 The present invention provides an embodiment of a solid-state hydrogen pool unit, the specific structure of which includes: a solid-state hydrogen pool single cell 1, and a plurality of groups of solid-state hydrogen pool single cells 1 are stacked side by side to form a tubular solid-state hydrogen pool unit 2.

[0038] The solid-state hydrogen pool system adopts a horizontal columnar module design, which can significantly save the layout space of passenger cars and greatly improve space utilization. The columnar hydrogen pool unit is compactly and efficiently integrated into the vehicle's hydrogen power system, effectively reducing the occupied space while ensuring sufficient hydrogen storage capacity to meet the needs of the vehicle under different driving conditions, thereby improving the vehicle's overall energy efficiency and power performance.

[0039] It should be explained in detail that in the solid-state hydrogen pool unit 2, a single solid-state hydrogen pool 1 is formed by combining a strong carbon fiber humidification tube 11 and a metal support frame 12, which realizes efficient hydrogen storage and hydrogen release functions. Specifically, the humidification tube 11 adopts a circular array layout, which is tightly fixed on the metal support frame 12. The humidification tube 11 is filled with a specific solid-state hydrogen storage material. The outside of the solid-state hydrogen pool unit 2 is provided with a nitrogen release device 3, which is connected to the heat exchange system 5 through this device, and works together to maintain the operating stability of the solid-state hydrogen pool unit 2.

[0040] During operation, multiple solid-state hydrogen pools 1 are stacked side by side to form a bundle-shaped solid-state hydrogen pool unit 2. This design allows the high-humidity air (humidity exceeding 90% RH) generated when the fuel cell engine is working to flow directly through the interior of the solid-state hydrogen pool carbon fiber humidification tube 11; since the humidification tube 11 adopts a reinforced carbon fiber tube, only water vapor is allowed to pass through its fiber wall to chemically react with the solid hydrogen storage material to release hydrogen; the heat generated in this process is circulated and exchanged through the heat exchange system 5 outside the solid-state hydrogen pool, thereby effectively dissipating excess heat, preventing internal overheating, and ensuring the safety and efficiency of the hydrogen storage and hydrogen release process.

[0041] During the design process, the hydrogen storage unit and the cooling chamber can be divided into single units and multiple units according to the magnitude, volume and weight required for the reaction, and then connected in series and parallel as needed; and the divided units can be quickly replaced in a modular manner, and the solid hydrogen pool that has completed the reaction first can be quickly extracted and replaced, or it can be replaced as a whole after the reaction release is completed, thereby conveniently realizing the energy replenishment of the solid hydrogen storage material, and in the environment of long-term operation or high-intensity use, it can minimize downtime and improve system reliability.

[0042] Through the modular design of the above-mentioned solid-state hydrogen pool unit 2, the storage density of the solid-state hydrogen storage material has been significantly improved, and the contact area between the material and the reaction liquid has been precisely controlled, so that the hydrogen release rate can be finely adjusted according to demand. This fine control not only improves the efficiency of hydrogen release, but also enables the system to respond flexibly under different working conditions; and the structure of the metal support frame 12 combined with the cooling cavity in the interlayer further enhances the heat conduction and dissipation capabilities. During operation, the generated heat can be quickly and effectively dissipated through the heat exchange system 5, ensuring that the system can work stably under high load or extreme environmental conditions.

[0043] Please continue to refer to Figure 1-Figure 2 In this embodiment, both ends of the solid hydrogen cell 1 are respectively provided with a mixed gas inlet 13 and a mixed gas exhaust 14, and the inlet is connected to the fuel cell tail exhaust air duct and the tail exhaust duct through a humidification pipe 11 to ensure that the mixed gas can flow in and out smoothly.

[0044] Furthermore, a humidified air inlet 31 is provided on one side of the nitrogen release device 3, while a humidified air exhaust port 32 is provided on the other side to ensure that the reaction between nitrogen and the solid hydrogen storage material is more efficient and controllable; a cooling and heat exchange inlet 33 is provided on the top of one side of the nitrogen release device 3, while a cooling and heat exchange outlet 34 is provided on the bottom of the other side to prevent damage to the solid hydrogen pool unit 2 or a decrease in hydrogen production efficiency; a nitrogen collection port 35 is provided on the top of the nitrogen release device 3 to capture and buffer the released hydrogen; a hydrolyzate flushing inlet 36 and a hydrolyzate flushing discharge port 37 are provided on both sides of the bottom of the nitrogen release device 3 to realize the collection of tail liquid.

[0045] Reference Figure 3 The present invention also provides an embodiment of a solid-state hydrogen pool operation system, the solid-state hydrogen pool operation system includes the solid-state hydrogen pool unit 2 as in the above embodiment, and also includes: a hydrogen release subsystem 4, the hydrogen release subsystem 4 includes a hydrogen pool composite plate unit, a hydrogen pool heat exchange manifold unit, a pressure signal acquisition unit, a temperature signal acquisition unit, a hydrogen pool system control unit, a hydrogen pool tail liquid storage unit, a hydrogen pool hydrogen storage buffer device, a hydrogen pool cooling and heat exchange device and a hydrogen pool electrical control device.

[0046] Exemplarily, the hydrogen pool composite plate unit can adopt a multi-layer composite material structure, and the surface has good catalytic activity, which can provide the necessary catalytic reaction conditions during the desorption process of the solid hydrogen storage material. The composite plate is built with a gas distribution channel and a liquid distribution channel to ensure sufficient contact and reaction between hydrogen and the hydrolysis liquid, and the release rate of hydrogen is regulated by changing the volume ratio of the hydrolysis liquid, thereby providing a stable hydrogen supply for the fuel cell system; the hydrogen storage buffer device is usually composed of a high-strength airtight container and a gas flow regulating device, which enters through the gas pipeline of the buffer device and controls the flow through a regulating valve, which can provide instant hydrogen supply during the peak demand for hydrogen, and store excess hydrogen when the demand for hydrogen is low to maintain the stability of the system. The hydrogen pool heat exchange manifold unit is mainly composed of a heat exchange pipe and a distribution manifold. Temperature control is achieved through heat exchange between the coolant and the hydrogen reaction chamber. The heat exchange manifold uses a high thermal conductivity material to ensure that the temperature inside the hydrogen pool is within a reasonable range to avoid malfunctions caused by excessive temperature. The cooling and heat exchange device is composed of a coolant flow channel and a heat exchange plate. The liquid circulation system performs heat exchange through multiple layers of heat exchange plates, and effectively removes the heat generated during the release of hydrogen through a coolant (such as water or other coolants). The tail liquid storage unit is composed of a sealed container and a liquid delivery pipeline connected to it. The container design of the tail liquid storage unit has good corrosion resistance and sealing properties to prevent tail liquid leakage and contamination. The pressure signal acquisition unit and the temperature signal acquisition unit are composed of sensors and signal processing modules. The pressure sensor is installed at key positions of the hydrogen pool (such as gas inlet, outlet, etc.) to monitor the pressure changes inside the hydrogen pool in real time. The temperature sensor is distributed in multiple areas of the hydrogen pool to monitor the temperature changes inside the hydrogen pool in real time. The hydrogen pool system control unit can use a high-performance microprocessor and an embedded software system, which can monitor and process various sensor data in real time. The control system signal adopts closed-loop processing. In order to ensure the coordination and consistency of the data with the upstream control system, CAN signals are uniformly used for interaction to reduce the effectiveness and convenience of quantitative transmission. The electrical control device includes various electrical components (such as relays, switches, sensors, actuators, etc.) and circuit boards. The control device is designed with explosion-proof and anti-interference characteristics to ensure safety in a hydrogen environment.

[0047] Reference Figure 4 The present invention also provides an embodiment of a solid-state hydrogen pool heat exchange system 5, which is used to circulate heat exchange on the solid-state hydrogen pool unit 2 in the above embodiment. The solid-state hydrogen pool heat exchange system 5 includes: a temperature detection sensor, a pressure detection sensor, a circulating water pump, a radiator, a filter, and a liquid replenishing tank.

[0048] In the solid hydrogen pool unit 2, a certain amount of heat is generated due to the adsorption and release reaction of hydrogen. The water pump circulates the coolant through the filter and the radiator to gradually remove the heat to avoid system failure due to overheating. The radiator effectively dissipates the heat released in the solid hydrogen pool unit 2 to the environment through the cooperation of the external heat dissipation core and the heat dissipation fan, thereby keeping the temperature of the system within a safe range.

[0049] The filter is connected to the water pump and the radiator to filter impurities and clean the liquid, thereby ensuring the efficient operation of the cooling system. In addition, the refilling tank is connected to the mixed gas inlet 13 of the solid hydrogen pool unit 2 through the liquid addition exhaust pipe to provide necessary supplementary liquid. If the coolant in the system is lost due to evaporation or other reasons, the refilling tank can be replenished in time to maintain the stability of the liquid circulation. The path of the coolant flow is: the coolant first enters the solid hydrogen pool unit 2, takes away the heat through heat exchange, flows out and passes through the filter and radiator, and is finally pumped back into the solid hydrogen pool unit 2 by the water pump to complete a cycle. By controlling the flow rate, temperature and other parameters of the coolant, the system can achieve precise heat exchange control of each component inside the solid hydrogen pool unit 2, thereby effectively adjusting the hydrogen release rate.

[0050] The temperature detection sensor and the pressure detection sensor monitor the working status of the entire system in real time, automatically adjust the running speed of the water pump and the flow rate of the coolant, and ensure the stable operation of the system under different loads. The system will automatically adjust the flow rate and temperature of the coolant according to the real-time temperature and pressure data to optimize the heat release and the adsorption and release rate of hydrogen. Through this efficient thermal management and control strategy, the system can ensure the safety, stability and efficiency of the solid-state hydrogen pool unit 2 under various working environments, thereby improving the overall performance of hydrogen storage and release.

[0051] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
