Description

Technical Field

[0001] The present application relates to the field of fuel cell thermal control technology, and in particular to a structural plate fuel cell and an electronic device having the same. Background Art

[0002] As an emerging clean energy conversion device, fuel cells have received extensive attention and application in various fields in recent years due to their advantages such as high efficiency, environmental protection, and long life. Most traditional fuel cell systems adopt a stacked stack structure, that is, several fuel cell units are tightly stacked to form a stack, thereby improving energy density and output power. Although the design of the stacked stack has good performance and economy in the ground environment, in some special application scenarios, such as aerospace, high-temperature industrial environments, etc., the heat dissipation effect of the stacked structure is poor.

[0003] Current fuel cell thermal management technologies mainly rely on two methods: circulating water cooling and air cooling. Circulating water cooling removes the heat generated during the battery reaction by the flow of coolant inside the fuel cell and conducts it to the external heat exchanger for heat dissipation. Air cooling uses air flow to remove the heat on the battery surface. These two methods are widely used in conventional ground applications, especially for high-power, high-density fuel cell systems.

[0004] However, circulating water cooling systems often require more complex pipes, pumps and other devices, which increase the weight and volume of the system, and there are also problems with the risk of coolant leakage and the working stability of the coolant in extreme environments. For air-cooled systems, in a vacuum or thin air environment, air convection fails and air cooling can hardly work. In special environments such as aerospace, traditional cooling systems often cannot ensure long-term stable operation, which may cause equipment failure due to poor heat dissipation. Summary of the invention

[0005] The present application provides a structural plate fuel cell and an electronic device having the same, so as to solve the technical problem that the cooling system of the existing fuel cell is difficult to ensure long-term stable operation under special circumstances.

[0006] In a first aspect, the present application provides a structural plate fuel cell, including a battery assembly, wherein the outer surface of the battery assembly is coated with a thermal control coating, and the battery assembly includes:

[0007] A battery panel, the battery panel comprising a first mounting surface and a second mounting surface which are arranged opposite to each other, at least one mounting position is formed on the first mounting surface, each of the mounting positions is arranged at intervals, and each of the mounting positions is provided with a panel cathode contact point and a panel anode contact point; and

[0008] At least one fuel cell, each of the fuel cells is correspondingly arranged in each of the installation positions, the battery cathode contact point of the fuel cell is in contact and connected with the corresponding cathode contact point of the electric plate, and the battery anode contact point of the fuel cell is in contact and connected with the corresponding anode contact point of the electric plate.

[0009] Optionally, a common hydrogen inlet and a common oxygen inlet are provided on the battery plate, and a hydrogen channel and an oxygen channel are formed inside the battery plate, one end of the hydrogen channel is connected to the common hydrogen inlet, and the other end of the hydrogen channel is connected to the hydrogen cavity of each of the fuel cells; one end of the oxygen channel is connected to the common oxygen inlet, and the other end of the oxygen channel is connected to the oxygen cavity of each of the fuel cells.

[0010] Optionally, the battery panel further includes a plurality of side surfaces, and the first mounting surface and the second mounting surface are connected via the plurality of side surfaces;

[0015] Optionally, each of the fuel cells is arranged on the battery plate in a flat arrangement.

[0016] Optionally, the fuel cell is screwed onto the battery plate.

[0017] Optionally, the battery panel is provided in a plate-shaped structure, and the first mounting surface and the second mounting surface are two surfaces in a thickness direction of the battery panel.

[0018] In a second aspect, the present application provides an electronic device comprising the structural plate fuel cell as described in the first aspect.

[0019] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0020] The structural plate fuel cell and the electronic device having the same provided in the embodiments of the present application adopt a standardized module design for a single fuel cell, and each module can be independently operated, tested and maintained. Users can increase or decrease the number of battery modules of the fuel cell according to different power requirements without making major changes to the entire system. The modular design greatly improves the maintainability of the fuel cell. The fuel cell is integrated into the battery plate in a tiled arrangement. This distributed arrangement not only improves the space utilization, but also enhances the system's impact and vibration resistance. The distributed design ensures the stability of the battery module in high vibration and high impact environments, and is particularly suitable for use in high-risk equipment such as aerospace vehicles.

[0021] By coating the outer surface of the battery assembly with a thermal control coating that has the characteristics of low absorption and high emission, the thermal control coating has an extremely low optical absorptivity, which can effectively reduce the absorption of thermal radiation in the external environment. At the same time, its high infrared emissivity ensures that the fuel cell can quickly dissipate heat through radiation heat dissipation in a vacuum or high temperature environment to prevent the fuel cell from overheating. By using a thermal control coating, the structural plate fuel cell system in this application does not require a traditional air cooling or water cooling system to dissipate heat, but instead dissipates heat to the external environment through radiation. This passive thermal management method greatly simplifies the system design and reduces potential failure points. BRIEF DESCRIPTION OF THE DRAWINGS

In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0031] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

[0032] See also Figure 1 and Figure 2An embodiment of the present application provides a structural plate fuel cell, including a battery assembly, the outer surface of which is coated with a thermal control coating, and the battery assembly includes a battery plate 1 and at least one fuel cell 5.

[0033] The battery panel 1 comprises a first mounting surface and a second mounting surface 4 which are arranged opposite to each other, wherein at least one mounting position is formed on the first mounting surface, each of the mounting positions is arranged at intervals, and each of the mounting positions is provided with a panel cathode contact point and a panel anode contact point.

[0034] Each of the fuel cells 5 is correspondingly arranged in each of the installation positions, the battery cathode contact point of the fuel cell 5 is in contact and connected with its corresponding cathode contact point of the electric plate, and the battery anode contact point 14 of the fuel cell 5 is in contact and connected with its corresponding anode contact point of the electric plate.

[0035] Specifically, when multiple fuel cells 5 are provided, the multiple fuel cells 5 are laid flat on the first mounting surface of the battery panel 1, and the fuel cells 5 are positioned in the mounting positions of the battery panel 1, thereby realizing modular assembly of the fuel cells 5 and improving the scalability and flexibility of the system through modular design.

[0036] The structural plate fuel cell provided in the embodiment of the present application adopts a standardized module design for a single fuel cell 5, and each module can be independently operated, tested and maintained. Users can increase or decrease the number of battery modules of the fuel cell 5 according to different power requirements without making major changes to the entire system. The modular design greatly improves the maintainability of the fuel cell 5. The fuel cell 5 is integrated into the battery plate 1 in a tiled arrangement. This distributed arrangement not only improves the space utilization, but also enhances the system's impact and vibration resistance. The distributed design ensures the stability of the battery module in high-vibration and high-impact environments, and is particularly suitable for use in high-risk equipment such as aerospace vehicles.

[0037] Among them, the battery anode contact point 14 and the battery cathode contact point 15 of the fuel cell 5 are respectively connected to the corresponding positive and negative electrodes on the battery plate 1, and the current and voltage generated by the fuel cell 5 are collected through contact to achieve a cable-free design.

[0038] By coating the outer surface of the battery assembly with a thermal control coating that has the characteristics of low absorption and high emission, the thermal control coating has an extremely low optical absorptivity, which can effectively reduce the absorption of thermal radiation in the external environment. At the same time, its high infrared emissivity ensures that the fuel cell 5 can quickly dissipate heat by radiation heat dissipation in a vacuum or high temperature environment to prevent the fuel cell 5 from overheating. By using a thermal control coating, the structural plate fuel cell system in this application does not require a traditional air cooling or water cooling system to dissipate heat, but instead dissipates heat to the external environment by radiation. This passive thermal management method greatly simplifies system design and reduces potential failure points.

[0039] Among them, the thermal control coating includes organic coatings such as SR107 or inorganic coatings such as KS-ZA. The thermal control coating material has the characteristics of low absorption and high emissivity, and dissipates the heat generated during the reaction of the fuel cell 5 to the external environment by radiation, thereby eliminating the need to rely on traditional cooling media (such as water or air), greatly simplifying the design and operation and maintenance of the system.

[0040] In some embodiments, the thermal control coating is filled with sterilizing powder, and the proportion of the sterilizing powder is between 0.5% and 5%. The sterilizing powder includes silver-loaded titanium dioxide powder. By filling the thermal control coating with silver-loaded titanium dioxide powder, the thermal control coating has antibacterial and antibacterial properties in addition to the properties of thermal radiation, giving the thermal control coating a sterilizing function, which can effectively inhibit the growth of bacteria on the coating surface, thereby ensuring that the surface of the structural plate remains clean.

[0041] Of course, in order to ensure the thermal radiation effect of the thermal control coating, when the sterilization powder is filled in the thermal control coating, the ratio of other powders in the thermal control coating is not changed.

[0042] In addition, a hydrophobic layer is provided outside the thermal control coating, and the hydrophobic layer includes a silicon dioxide coating, and the thickness of the silicon dioxide coating is at the nanometer level, which achieves certain hydrophobic and dust-repellent properties, and ensures the cleanliness of the surface of the battery plate 1. Specifically, the silicon dioxide nanolayer on the surface of the thermal control coating has excellent hydrophobic and dust-repellent properties, making it difficult for water droplets and dust to adhere to the coating surface, and maintaining the cleanliness of the surface of the battery plate 1 and the efficient heat dissipation effect.

[0043] Specifically, the fuel cell 5 is detachably arranged on the battery plate 1, and the fuel cell 5 can be assembled according to the actual needs of the user. By detachably arranging the fuel cell 5, it is convenient to adjust the number of fuel cells 5 on the battery plate 1 and the layout of the fuel cell 5 on the battery plate 1, so as to adapt to different application scenarios and different application needs, and improve the scalability and flexibility of the system. Optionally, the fuel cell 5 is screwed to the battery plate 1, or the fuel cell 5 is snap-connected to the battery plate 1. Exemplarily, the fuel cell 5 is threadedly connected to the battery plate 1 by screws. In order to ensure the reliability of the connection, a plurality of screws are provided, and the fuel cell 5 is threadedly connected to the battery plate 1 by a plurality of screws, wherein the plurality of screws can be respectively provided at each corner of the fuel cell 5. For example, the fuel cell 5 is arranged in a rectangular plate-like structure, and the fuel cell 5 is laid flat on the battery plate 1. At this time, four screws are provided, and the four screws are respectively provided at the four corners of the fuel cell 5, and are used to thread the fuel cell 5 and the battery plate 1 together to ensure stable mechanical properties.

[0044] Reference Figure 1 At least one mounting position is formed on the first mounting surface of the battery plate 1, and each mounting position is provided with a plate cathode contact point and a plate anode contact point. The battery cathode contact point 15 of the fuel cell 5 is in contact with and connected to the corresponding plate cathode contact point, and the battery anode contact point 14 of the fuel cell 5 is in contact with and connected to the corresponding plate anode contact point. Thus, the battery plate 1 is in contact with the fuel cell 5 to collect current and realize a cable-free design.

[0045] The battery plate 1 is provided with a hydrogen common inlet 2, an oxygen common inlet 3, a hydrogen common outlet and an oxygen common outlet. A hydrogen channel and an oxygen channel are formed inside the battery plate 1. One end of the hydrogen channel is connected to the hydrogen common inlet 2, and the other end of the hydrogen channel is connected to the hydrogen cavity of each of the fuel cells 5; one end of the oxygen channel is connected to the oxygen common inlet 3, and the other end of the oxygen channel is connected to the oxygen cavity of each of the fuel cells 5. The hydrogen and oxygen in the fuel cell 5 react through an electrochemical reaction to generate electricity and heat. The reaction is continuous in the fuel cell 5. As long as hydrogen and oxygen are continuously supplied, the fuel cell 5 can continuously generate electrical energy.

[0046] The hydrogen channel connects the hydrogen common inlet 2, the hydrogen cavity of the fuel cell 5, and the hydrogen common outlet. Hydrogen enters the interior of the battery plate 1 through the hydrogen common inlet 2, and then flows to the hydrogen cavity of the fuel cell 5. After entering the interior of the fuel cell 5, it is used to react with oxygen. Excess hydrogen flows out and is discharged through the hydrogen common outlet. The oxygen channel connects the oxygen common inlet 3, the oxygen cavity of the fuel cell 5, and the oxygen common outlet. Oxygen enters the interior of the battery plate 1 through the oxygen common inlet 3, and then flows to the oxygen cavity of the fuel cell 5. After entering the interior of the fuel cell 5, it is used to react with hydrogen. Excess oxygen flows out and is discharged through the oxygen common outlet.

[0047] The hydrogen and oxygen in the fuel cell 5 react through an electrochemical reaction, and the water generated as a byproduct needs to be discharged in time to maintain the normal operation of the battery. The water generated by the reaction is discharged through the oxygen common outlet.

[0048] Reference Figure 1 and Figure 2 Specifically, the fuel cell 5 is composed of an anode plate 6, a cathode plate 7, and a membrane electrode 8 located between the anode plate 6 and the cathode plate 7. The cathode plate 7 is provided with a hydrogen inlet 9, a hydrogen outlet 11, an oxygen inlet 10, and an oxygen outlet 12. The anode plate 6 is provided with an anode plate flow field 13 on the side facing the cathode plate 7, and the cathode plate 7 is provided with a cathode plate flow field on the side facing the anode plate 6. The hydrogen flowing to the fuel cell 5 through the hydrogen common inlet 2 enters the anode plate flow field 13 through the hydrogen inlet 9, contacts the membrane electrode 8 to undergo an oxidation reaction, and the excess hydrogen flows out through the hydrogen outlet 11 of the fuel cell 5 and then enters the battery plate 1. The oxygen flowing to the fuel cell 5 through the oxygen common inlet 3 enters the cathode plate flow field through the oxygen inlet 10 on the cathode plate 7, contacts the membrane electrode 8 to undergo a reduction reaction to generate water, and the excess oxygen and the generated water flow out of the fuel cell 5 through the oxygen outlet 12 and flow into the battery plate 1.

[0049] The hydrogen outlet 11 can also flow with the hydrogen common inlet 2 in the battery plate 1, so that excess hydrogen can be reused; the oxygen outlet 12 can also flow with the oxygen common inlet 3 in the battery plate 1, so that excess oxygen can be reused. In addition, the hydrogen cavity is the anode plate flow field 13, and the oxygen cavity is the cathode plate flow field.

[0050] The battery panel 1 also includes multiple side surfaces, and the first mounting surface and the second mounting surface 4 are connected through the multiple side surfaces; the hydrogen common inlet 2, the oxygen common inlet 3, the hydrogen common outlet and the oxygen common outlet are all arranged on the side surfaces; and gas is introduced into the interior of the battery panel 1 by opening the side surfaces of the battery panel 1.

[0051] The hydrogen common inlet 2 and the oxygen common inlet 3 are arranged on the same side, and the hydrogen common outlet and the oxygen common outlet are arranged on the same side; the hydrogen common inlet 2 and the oxygen common inlet 3 are arranged on the same side of the battery panel 1, and the hydrogen common outlet and the oxygen common outlet are arranged on the same side of the battery panel 1, which can facilitate the connection of the gas pipeline on the battery panel 1 and facilitate the assembly of the overall device.

[0052] Both ends of the hydrogen channel and both ends of the oxygen channel are provided with sealing members; the provision of the sealing members ensures the stable flow of gas and liquid, and can effectively prevent leakage of gas or liquid.

[0053] The battery panel 1 is arranged in a plate-like structure, and the first mounting surface and the second mounting surface 4 are two sides of the battery panel 1 in the thickness direction; the first mounting surface is used to assemble the fuel cell 5, and the first mounting surface and the second mounting surface 4 are two sides of the battery panel 1 in the thickness direction, which can ensure the area of ​​the first mounting surface, and as many fuel cells 5 as possible can be assembled thereon to meet the usage requirements of different users.

[0054] It can be known that the battery plate 1 can be a rectangular plate structure, a triangular plate structure or other polygonal structure, and its specific structure can be adaptively selected according to different matching equipment.

[0055] The corners of the battery panel 1 may also be rounded. The rounded corner structure ensures the roundness of the edge of the battery panel 1, making it easier for users to pick it up and use it, and avoiding scratches on users.

[0056] In summary, the structural plate fuel cell provided by the present application achieves efficient heat dissipation through the low-absorption and high-emission thermal control coating, which is particularly suitable for vacuum environments without air medium and with extreme temperature changes. Through the radiation heat dissipation method, the stable operation of the fuel cell 5 system in special environments is ensured, the heat dissipation problem of traditional fuel cells 5 in such scenarios is solved, and efficient thermal management is achieved.

[0057] Traditional circulating water cooling and air cooling systems are complex in design and often require additional auxiliary equipment such as pumps, fans, coolants, etc., which increase the weight, volume and complexity of the system. The passive self-radiative heat management technology of the structural plate fuel cell provided in this application does not require these auxiliary equipment, greatly simplifies the structural design of the fuel cell 5, making it lighter, more compact and more adaptable.

[0058] In addition, the modular and distributed arrangement of the structural plate design makes the system more flexible. The battery module of the single fuel cell 5 can flexibly adjust the number of batteries according to the power requirements of the specific application scenario, and is suitable for different application scenarios from small portable devices to large spacecraft. Compared with the traditional stacked battery stack, the distributed arrangement has more structural stability and effectively reduces the risk of failure caused by vibration, impact or deformation. In addition, the distributed design is also suitable for irregularly shaped equipment, which enhances the adaptability of the system.

[0059] By reducing moving parts, liquid circulation and mechanical cooling systems, the potential risk of failure is significantly reduced, gas circulation, power consumption required by cooling water circulation pumps are omitted, and zero-power water-gas thermal management is achieved. The fuel cell 5 system can still maintain good stability under long-term high-load operation, and is particularly suitable for equipment that requires high reliability and long-term stable operation.
