Description

Technical Field

[0001] This application relates to the field of water electrolysis for hydrogen production technology, and in particular to electrolyzer devices and hydrogen production equipment. Background Technology

[0002] Electrolytic hydrogen production is a technology that generates hydrogen gas through the electrolysis of water. Its basic principle is to decompose water into hydrogen and oxygen. The electrolyzer is the core equipment in electrolytic hydrogen production. When the electrolyzer is connected to a DC power source, water is decomposed into hydrogen and oxygen. Hydrogen is mainly produced in the cathode chamber, while oxygen is produced in the anode chamber. In most related technologies, the electrolyzer is composed of multiple stacked electrode assemblies, with adjacent electrodes forming an electrolysis chamber. To tightly combine multiple electrolysis chambers, external pressure is needed to ensure a seal between them. Existing technologies mostly use screws and nuts to achieve this sealing connection. However, this sealing method makes disassembly of the electrolysis chambers difficult, resulting in low assembly and disassembly efficiency and thus affecting the development progress of the electrolyzer. Utility Model Content

[0003] Therefore, it is necessary to provide an electrolyzer device and hydrogen production equipment to address the problem that the disassembly and assembly efficiency of existing electrolyzers is low, which affects the research and development progress of electrolyzers.

[0018] The second frame plate consists of two plates, which are arranged opposite each other and spaced apart along a second direction that intersects with the first direction; each second frame plate is connected to the two first frame plates at both ends.

[0019] The two first frame plates and the two second frame plates together enclose the first installation space.

[0020] In some embodiments, the hydraulic assembly includes:

[0021] Drive components; and

[0022] A telescopic rod is connected to the power output end of the drive component, and the end of the telescopic rod away from the drive component is fixedly connected to the electrolytic cell assembly.

[0032] The control panel is communicatively connected to the hydraulic component; the control panel is used to control the hydraulic component.

[0046] See Figures 1-4 , Figure 1 A schematic diagram of an electrolyzer apparatus provided in some embodiments of this application installed on a hydrogen production device is shown. Figure 2 It shows Figure 1 The front view of the hydrogen production equipment shown. Figure 3 It shows Figure 1 Left view of the hydrogen production equipment shown. Figure 4 It shows Figure 1 The diagram shows a top view of a hydrogen production device. An embodiment of this application provides an electrolyzer apparatus, which includes a support assembly 100, an electrolyzer assembly 200, and a hydraulic assembly 300. The electrolyzer assembly 200 includes a plurality of electrolysis chambers 210 arranged sequentially along a first direction, and each electrolysis chamber 210 is slidably connected to the support assembly 100; specifically, the first direction is... Figure 1 and Figure 2 The direction of xx' in the middle; the power output end of the hydraulic component 300 is fixedly connected to one end of the electrolytic cell component 200; and the hydraulic component 300 can drive the electrolytic chamber 210 to move along the first direction.

[0047] In the aforementioned electrolytic cell device, since the power output end of the hydraulic component 300 is fixedly connected to one end of the electrolytic cell component 200, the electrolytic cell 210 can be moved along the first direction by the drive of the hydraulic component 300, thereby changing the distance between multiple electrolytic cells 210, thus achieving rapid sealing or disassembly of the electrolytic cells 210, making the disassembly and assembly efficiency of the entire electrolytic cell high, thereby improving the research and development progress of the electrolytic cell and meeting the needs for rapid testing, rapid iteration, rapid research and development and market launch of new materials and new products.

[0048] This application adds a hydraulic component 300 to the electrolytic cell device, thereby enabling rapid assembly and disassembly of the electrolytic cell device, improving experimental efficiency, and shortening the iteration cycle of "new materials and new products" research and development.

[0049] In some embodiments, the hydraulic component 300 is the hydraulic component 300 of the filter press. This application combines the hydraulic component 300 of the filter press with the electrolysis chamber 210, and uses a mature hydraulic pump system to achieve rapid clamping and pressure unloading of the electrolysis chamber 210, thereby realizing the rapid assembly and disassembly of the electrolysis cell device.

[0050] The following is a detailed description of the structure of the electrolytic cell apparatus.

[0051] Please see Figure 5 , Figure 5 This diagram illustrates the assembly of an electrolytic cell assembly 200 with a second frame plate 120 in an electrolytic cell apparatus provided in some embodiments of this application. In some embodiments, the electrolytic cell assembly 200 further includes an elastic member 220; the elastic member 220 is installed between two adjacent electrolytic cells 210. By providing the elastic member 220 between two adjacent electrolytic cells 210, the elastic member 220 can undergo elastic deformation when the electrolytic cells 210 move along the first direction, thereby making the movement of the electrolytic cells 210 more stable through the elastic deformation of the elastic member 220. Furthermore, due to the presence of the elastic member 220, the abutting force between multiple electrolytic cells 210 can be transmitted through the elastic member 220, making the abutting or tensile force on each electrolytic cell 210 more balanced, reducing the possibility of damage when the end face of the end electrolytic cell 210 is subjected to a large abutting or tensile force.

[0052] Please see Figure 1 and combined Figures 2-5In some embodiments, the electrolysis chamber 210 includes a chamber body 211 and a hanging ear 212. The hanging ear 212 is connected to the chamber body 211 and has a mounting groove 2121; the groove wall of the mounting groove 2121 is slidably connected to the support assembly 100. By providing the mounting groove 2121 on the hanging ear 212, the electrolysis chamber 210 can move relative to the support assembly 100 in a first direction by sliding the groove wall of the mounting groove 2121 relative to the support assembly 100, and the entire movement process is relatively smooth.

[0053] This application suspends each electrolysis cell 210 on the support assembly 100 by setting tabs on each cell body 211. After the hydraulic system's clamping force is unloaded with a "one-click" operation, each electrolysis cell 210 can be individually disassembled and assembled by a single person.

[0054] Please see Figure 4 and Figure 5 In some embodiments, each electrolysis chamber 210 includes at least two lugs 212, and the at least two lugs 212 are arranged opposite to each other. By providing at least two lugs 212 to each electrolysis chamber 210, each electrolysis chamber 210 can move through the cooperation of the mounting slots 2121 of the two lugs 212, making the movement of the electrolysis chamber 210 smoother.

[0055] Please see Figure 1 and Figure 4 In some embodiments, the support component 100 is configured with a first mounting space 101; the electrolytic cell assembly 200 is at least partially housed within the first mounting space 101. By providing the first mounting space 101 on the support component 100 and ensuring that the electrolytic cell assembly 200 is at least partially housed within the first mounting space 101, the support component 100 can protect the electrolytic cell assembly 200, making the electrolytic cell assembly 200 safer during movement and use.

[0056] Please see Figures 1-4 In some embodiments, the support assembly 100 includes a first frame plate 110 and a second frame plate 120. There are two first frame plates 110, which are positioned opposite each other and spaced apart along a first direction; there are also two second frame plates 120, which are positioned opposite each other and spaced apart along a second direction, which intersects the first direction; specifically, the second direction is... Figure 1 and Figure 4The first frame plate 120 is connected to two first frame plates 110 at both ends; the two first frame plates 110 and the two second frame plates 120 together form a first mounting space 101. By forming the first mounting space 101 together with the two first frame plates 110 and the two second frame plates 120, when the mounting groove 2121 assembly is at least partially housed in the first mounting space 101, the first frame plates 110 and the second frame plates 120 can protect the mounting groove 2121 assembly, thereby making the mounting groove 2121 assembly less susceptible to collision damage from the external environment during use.

[0057] Please see Figure 1 and Figure 4 In some embodiments, the hydraulic assembly 300 includes a drive member 310 and a telescopic rod. The telescopic member 320 is driven to the power output end of the drive member 310, and the end of the telescopic rod away from the drive member 310 is fixedly connected to the electrolytic cell assembly 200. The drive member 310 is used to drive the telescopic rod to extend and retract along its own extension direction. By driving the telescopic rod to extend and retract along its own extension direction through the drive member 310, one end of the electrolytic cell assembly 200 is moved along a first direction, thereby realizing the movement of the electrolysis chamber 210 along the first direction, which is relatively simple and convenient.

[0058] Please see Figures 1-3 In some embodiments, the support component 100 further comprises a second mounting space 102; the second mounting space 102 and the first mounting space 101 are arranged along the direction of gravity; and the second mounting space 102 is located below the first mounting space 101; the drive member 310 is installed in the second mounting space 102. By setting the second mounting space 102, and arranging the second mounting space 102 and the first mounting space 101 along the direction of gravity, and with the second mounting space 102 located below the first mounting space 101, the drive member 310 is installed in the lower second mounting space 102, saving the size of the entire electrolytic cell device along the first direction, making the structure of the entire electrolytic cell device more compact along the first direction.

[0059] In some embodiments, the electrolytic cell apparatus further includes a temperature sensor and a controller. The temperature sensor is mounted on the electrolytic cell assembly 200 to detect the temperature of the electrolytic cell assembly 200. The controller is communicatively connected to the temperature sensor and to the hydraulic assembly 300. When the temperature detected by the temperature sensor is outside a preset range, the controller controls the hydraulic assembly 300 to move the electrolytic chamber 210 along a first direction. By setting a temperature sensor and mounting it on the electrolytic cell assembly 200 to detect the temperature of the electrolytic cell assembly 200, the controller can dynamically control the hydraulic assembly 300 according to the temperature detected by the temperature sensor, automatically moving the electrolytic chamber 210 along the first direction, so that the clamping force of each electrolytic chamber 210 in the entire electrolytic cell apparatus is always maintained at a relatively constant set value.

[0060] This application utilizes the combined action of a temperature sensor and a controller to automatically regulate the operation of the hydraulic system, thereby maintaining the clamping force of the entire electrolytic cell unit at a constant set value.

[0061] In some embodiments, when the temperature detected by the temperature sensor is lower than a preset range, it indicates that the temperature of the electrolytic cell assembly 200 is low. Due to the characteristics of thermal expansion and contraction, the sealing performance of each electrolytic cell 210 may be poor. At this time, the controller controls the hydraulic assembly 300, thereby driving each electrolytic cell 210 to move along the first direction, thereby reducing the distance between the electrodes of each electrolytic cell 210 and improving the sealing performance of the electrolytic cell 210.

[0062] In some embodiments, when the temperature detected by the temperature sensor exceeds a preset range, it indicates that the temperature of the electrolytic cell assembly 200 is high. Due to the characteristics of thermal expansion and contraction, the contact force between the electrodes of each electrolytic cell 210 may be excessive, potentially leading to damage. At this time, the controller controls the hydraulic assembly 300, thereby moving each electrolytic cell 210 along a first direction, increasing the distance between the electrodes of each electrolytic cell 210, and thus reducing the contact force between the electrodes of each electrolytic cell 210.

[0063] Please see Figure 1 , Figure 2 and Figure 4 This application also provides a hydrogen production device, which includes the electrolyzer apparatus described in any of the above embodiments; it also includes an operating table 400; the operating table 400 is communicatively connected to the hydraulic component 300; the operating table 400 is used to control the hydraulic component 300. The hydrogen production device provided by the embodiments of this application can achieve at least one of the above-mentioned technical effects. By setting up the operating table 400, the user can control the entire electrolyzer apparatus from the operating table 400, thereby making the control of the electrolyzer apparatus more convenient.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
