[0037] This application proposes an electrolytic cell.
[0038] Please see Figures 1 to 4 In one embodiment of this application, the electrolytic cell includes a plurality of stacked electrode plates 100 and a flow guide 200 disposed on at least one electrode plate 100. The plurality of electrode plates 100 form a flow guide channel 400 extending along the axial direction of the electrode plate 100. The flow guide 200 communicates with the flow guide channel 400 and is used to allow fluid to flow through the flow guide channel 400 so that the current detector 300 can detect the current data of the fluid. The fluid is an electrolyte or an electrolysis product.
[0039] Specifically, the flow channel 400 is used to supply fluid flow. The flow channel 400 can be an electrolyte channel, where the fluid flowing within is the electrolyte; or it can be an electrolysis product channel, where the fluid flowing within is the electrolysis product, specifically a gas-liquid mixture of hydrogen or oxygen and the electrolyte. Both the electrolyte and electrolysis products within the flow channel 400 carry a certain amount of charge. During actual operation of the electrolyzer, when a given input current (i.e., the total current I) is applied, a portion of the current (electrolysis current Ia) is effectively used for water electrolysis, while the other portion flows out of the flow channel 400 and is not used for the water electrolysis reaction. Therefore, the current flowing out of the flow channel 400 is the bypass current Is.
[0040] The flow guide 200 is connected to the flow guide channel 400, allowing fluid within the flow guide channel 400 to flow through the flow guide 200. This facilitates real-time monitoring of the current data of the fluid flowing through the flow guide 200 by the current detector 300. The current detector 300 can monitor the current magnitude of the fluid flowing through the flow guide 200 in real time, thereby assessing the magnitude of the bypass current lost from the flow guide channel 400 based on the fluid's charge. Further analysis of the factors affecting the bypass current magnitude allows for targeted measures to optimize or reduce bypass current losses. For example, engineers can adjust process parameters and optimize the electrolyzer's structural design to ensure the stability and efficiency of the electrolysis process, thereby improving the electrolysis efficiency of the electrolyzer, increasing hydrogen production, and reducing energy consumption per standard cubic meter of hydrogen produced.
[0041] The technical solution of this application sets up a flow guide 200, which allows the fluid in the flow channel 400 to flow through the flow guide 200. This enables the current detector 300 to conveniently monitor the current data of the fluid flowing through the flow guide 200 in real time, so as to assess the magnitude of the bypass current. This allows for targeted measures to be taken to optimize or reduce the bypass current loss based on the magnitude and distribution of the bypass current, thereby improving the electrolysis efficiency of the electrolyzer, increasing hydrogen production, and reducing the energy consumption per standard cubic meter of hydrogen produced.
[0042] In one embodiment, the flow channel 400 includes at least two flow sections 410 distributed along the axial direction of the electrode plate 100, and at least two adjacent flow sections 410 are connected by a flow guide 200.
[0043] The flow channel 400 includes at least two flow sections 410. The two adjacent flow sections 410 are not directly connected. The two adjacent flow sections 410 are connected by a flow guide 200. The fluid in one flow section 410 can only flow from the flow guide 200 to the adjacent flow section 410. Thus, the current detector 300 can easily monitor the current data of the flow channel 400 in this area.
[0044] In one implementation, please refer to Figures 1 to 3 At least one electrode plate 100 is configured as a first electrode plate 110, and the inlet and outlet ends of the flow guide 200 are insulated from the first electrode plate 110.
[0045] There is no direct electrical connection between the inlet and outlet ends of the flow guide 200 and the first electrode plate 110. By using an insulating material (such as plastic or ceramic) as an isolation layer, the inaccurate current detection result of the current detector 300 caused by the current of the first electrode plate 110 flowing directly through the flow guide 200 can be avoided. This helps to ensure the accuracy of the detection result of the current detector 300, so that targeted measures can be taken to optimize or reduce the bypass current loss. Both the inlet and outlet ends of the flow guide 200 are insulated from the first electrode plate 110. The flow guide 200 can be made entirely of insulating material; or the flow guide 200 can be made of metal, and the connection between the flow guide 200 and the first electrode plate 110 can be insulated, such as by setting an insulating layer on the outer periphery of the flow guide 200; or the connection between the flow guide 200 and the first electrode plate 110 can be made of insulating material, while the rest is made of metal.
[0046] In other embodiments, the inlet and outlet ends of the flow guide 200 can also be connected to different electrode plates 100, and the inlet and outlet ends of the flow guide 200 are respectively insulated from the corresponding electrode plates 100.
[0047] In one implementation, please refer to Figures 3 to 5 The first electrode plate 110 has grooves 111 on opposite sides. The two grooves 111 on the same first electrode plate 110 are connected to the two adjacent guide sections 410 in a one-to-one correspondence. The two grooves 111 on the same first electrode plate 110 are connected by the guide member 200.
[0048] The first electrode plate 110 has grooves 111 on opposite sides. Each groove 111 on the same first electrode plate 110 is connected to an adjacent guide section 410. Fluid can flow from one guide section 410 into the groove 111, pass through the guide member 200, flow into another groove 111, and then into another guide section 410. The two grooves 111 on the same first electrode plate 110 are blocked in the axial direction of the first electrode plate 110 by the bottom of the groove 111, so that the fluid flows through the guide member 200. This avoids the two grooves 111 on the same first electrode plate 110 from being connected and causing a short circuit in the guide member 200. As a result, the current detector 300 installed on the guide member 200 can monitor the current change through the guide member 200 in real time, providing data support for operators to adjust operating parameters in a timely manner, optimize the production process, and improve electrolysis efficiency.
[0049] It is worth mentioning that when the inlet 510 is located at the end of the flow channel 400, the external electrolyte enters from the inlet 510 into one flow section 410 of the flow channel 400 and flows into the groove 111 on one side of the first electrode plate 110. It then flows through the guide member 200 to the groove 111 on the other side of the same first electrode plate 110, and then flows to another flow section 410. When the inlet 510 is located in the middle of the flow channel 400, the external electrolyte flows from the inlet 510 into the flow channel 400 and is split at the groove 111 on one side of the first electrode plate 110. Part of the electrolyte flows away from the groove 111 to one of the flow sections 410, and part of the electrolyte flows from the groove 111 through the guide member 200 to the groove 111 on the other side of the same first electrode plate 110, and then flows to another flow section 410. The same applies to the case where the electrolytic product outlet 520 is located at the end or middle of the guide channel 400, and will not be described in detail here.
[0050] In one implementation, please refer to Figures 3 to 5 The first electrode plate 110 is provided with a slot 112 that communicates with the groove 111, and the liquid inlet end and liquid outlet end of the guide 200 are inserted into the two slots 112 in a corresponding manner.
[0051] The first electrode plate 110 is also provided with a slot 112 communicating with the groove 111. The slot 112 penetrates the outer surface of the first electrode plate 110 and the sidewall of the groove 111. The function of the slot 112 is to provide a precise interface position for the flow guide 200, ensuring that the flow guide 200 can accurately dock with the first electrode plate 110. The inlet and outlet ends of the flow guide 200 are designed to be inserted into the slots 112 on the first electrode plate 110, allowing the flow guide 200 to be directly connected to the first electrode plate 110, forming a sealed and efficient channel. Through the tight insertion of the slot 112 and the flow guide 200, it can be ensured that the fluid flows only within the predetermined path, reducing the risk of leakage and thus improving the system's sealing performance and operational reliability.
[0052] In one implementation, please refer to Figure 4 The slot of the slot 112 near the groove 111 is flush with the port of the guide 200.
[0053] The port of the guide 200 refers to the inlet or outlet port of the guide 200. When the slot of the slot 112 near the groove 111 is aligned with the port of the guide 200, the inlet port of the guide 200 is precisely aligned with the slot of one of the slots 112 near the groove 111, or the outlet port of the guide 200 is precisely aligned with the slot of another slot 112 near the groove 111. This ensures that the fluid does not encounter obstacles or unnecessary detours when flowing from the groove 111 into the guide 200, or from the guide 200 into the groove 111, thereby reducing fluid resistance and ensuring smooth fluid flow.
[0054] In another embodiment, the port of the flow guide 200 is located within the slot 112.
[0055] The port of the flow guide 200 is located entirely inside the slot 112, which can further reduce turbulence or obstruction of the fluid when entering or leaving the flow guide 200, and help maintain the smoothness and stability of the fluid flow.
[0056] In one embodiment, multiple first electrode plates 110 and flow guides 200 are provided, and the inlet and outlet ends of each flow guide 200 are insulatedly connected to the same first electrode plate 110.
[0057] By setting multiple flow guides 200 along the axial direction of the first electrode plate 110, and each flow guide 200 being insulated from the first electrode plate 110, and each flow guide 200 being equipped with a current detector 300, the current distribution at different positions along the axial direction of the flow channel 400 can be better monitored. Furthermore, based on the magnitude and distribution of the bypass current in the flow channel 400, the factors affecting the magnitude of the bypass current can be further analyzed, so as to take targeted measures to optimize or reduce the loss of bypass current, thereby improving the electrolysis efficiency of the electrolyzer, increasing hydrogen production, and reducing the energy consumption per standard cubic meter of hydrogen produced.
[0058] In other embodiments, only one of the first electrode plate 110 and the flow guide 200 may be provided.
[0059] In one implementation, please refer to Figure 1 and Figure 2 The liquid inlet 510 and / or the electrolytic product outlet 520 of the electrolytic cell are located on the first electrode plate 110.
[0060] The inlet 510 of the electrolytic cell is connected to the electrolyte channel for supplying electrolyte into the electrolytic cell. The electrolysis product outlet 520 of the electrolytic cell is connected to the electrolysis product channel for supplying hydrogen-alkali mixture or oxygen-alkali mixture out of the electrolytic cell. After the electrolyte enters the electrolyte channel through the inlet 510, it enters different electrolysis chambers (two adjacent electrode plates 100 enclose an electrolysis chamber connected to the electrolyte channel) along the extension direction of the electrolyte channel to carry out electrolysis reactions. After the electrolysis reaction is completed, the hydrogen or oxygen produced reacts with part of the electrolyte to form a hydrogen-alkali mixture or an oxygen-alkali mixture, and enters their respective electrolysis product channels, finally exiting the electrolytic cell from the electrolysis product outlet 520. The guide element 200, the inlet 510, and the electrolysis product outlet 520 are all located on the first electrode plate 110, which can integrate multiple interface structures onto one first electrode plate 110, facilitating centralized processing of the first electrode plate 110 and each interface structure.
[0061] In one implementation, please refer to Figures 1 to 3 The thickness of the first electrode plate 110 is greater than the thickness of the other electrode plates 100.
[0062] The thickness of the first electrode plate 110 is greater than that of the other electrode plates 100, so that a connecting pipe for welding to the liquid inlet 510 and the electrolytic product outlet 520 can be set on the first electrode plate 110. Furthermore, the greater thickness of the first electrode plate 110 compared to the other electrode plates 100 makes it easier to set the flow guide 200, and integrate the flow guide 200, the liquid inlet 510 and the electrolytic product outlet 520 on a single first electrode plate 110.
[0063] In one implementation, please refer to Figures 1 to 3 The thickness of the first electrode plate 110 is greater than the thickness of the other electrode plates 100, and the liquid inlet 510 and / or the electrolytic product outlet 520 of the electrolytic cell are located on the first electrode plate 110. The thickness of the first electrode plate 110 is greater than the thickness of the other electrode plates 100 so as to facilitate the provision of a connecting pipe on the first electrode plate 110 for welding to the liquid inlet 510 and the electrolytic product outlet 520.
[0064] In one implementation, please refer to Figure 6 The first electrode plate 110 is provided with an installation groove 113. The two side walls of the installation groove 113 in the axial direction are provided with connecting holes 114 that communicate with the guide section 410. The guide member 200 is provided in the installation groove 113 and communicates with the two connecting holes 114.
[0065] The mounting groove 113 on the first electrode plate 110 provides a mounting space for the flow guide 200, ensuring that it can be accurately installed in a predetermined position so that the current detector 300 can be mounted on the flow guide 200. The connecting holes 114 on both sides of the mounting groove 113 are directly connected to the adjacent flow guide section 410, allowing fluid to flow into or out of the flow guide 200 in the mounting groove 113 from one flow guide section 410 through the connecting holes 114. The mounting groove 113 prevents the flow guide 200 from protruding outward, reducing the risk of the flow guide 200 being accidentally impacted.
[0066] In one embodiment, multiple flow channels 400 are formed, and each flow channel 400 is provided with a flow guide 200.
[0067] The flow channel 400 includes an electrolyte channel, a hydrogen-alkali mixture channel, and an oxygen-alkali mixture channel. Each flow channel 400 is equipped with a flow guide 200, which allows for better monitoring of the current distribution in different flow channels 400. Furthermore, based on the magnitude and distribution of the bypass current in different flow channels 400, the factors affecting the magnitude of the bypass current can be further analyzed, so as to take targeted measures to optimize or reduce the bypass current loss, thereby improving the electrolysis efficiency of the electrolyzer, increasing hydrogen production, and reducing the energy consumption per standard cubic meter of hydrogen produced.
[0068] In other embodiments, the bypass current in the electrolyte channel is large, and the guide element 200 may be provided only in the electrolyte channel; of course, the guide element 200 may also be provided only in the hydrogen-alkali mixture channel or the oxygen-alkali mixture channel.
[0069] In one embodiment, the guide member 200 is connected to the electrode plate 100 by a threaded connection.
[0070] The flow guide 200 and the electrode 100 are connected by threads. Specifically, internal or external threads are machined into the flow guide 200 or the electrode 100, and the two are tightly connected by screwing. The threaded connection provides strong mechanical fixing force, effectively preventing loosening caused by vibration or other reasons in high-pressure or long-term stable operation environments; it also facilitates the maintenance of the flow guide 200 and the improvement of the insulation performance between the flow guide 200 and the electrode 100. Furthermore, a sealing material (such as a sealing ring or sealant) can be provided between the flow guide 200 and the electrode 100 to prevent fluid leakage.
[0071] In another embodiment, the flow guide 200 is connected to the electrode plate 100 by means of a flange connection.
[0072] Flanges are provided on both the flow guide 200 and the electrode plate 100. The flange faces of both are in contact and fastened with bolts. Sealing gaskets (such as rubber gaskets or metal gaskets) are also used to enhance the sealing performance. The flange connection between the flow guide 200 and the electrode plate 100 maintains higher mechanical strength and more reliable sealing under high-pressure electrolytic cells or high-flow-rate electrolyte conditions, ensuring stable operation of the electrolytic cell under harsh conditions. It also facilitates the maintenance of the flow guide 200 and the improvement of the insulation performance between the flow guide 200 and the electrode plate 100.
[0073] In another embodiment, the flow guide 200 is connected to the electrode plate 100 by adhesive bonding.
[0074] The flow guide 200 and the electrode plate 100 are connected by a specialized adhesive or sealant (such as an adhesive with corrosion resistance and high temperature resistance). The adhesive bonding between the flow guide 200 and the electrode plate 100 forms a very tight sealing layer, effectively preventing fluid leakage. Compared to threaded or flanged connections, adhesive bonding is generally simpler and faster, reducing complex fastener installation steps and lowering assembly difficulty and time costs.
[0075] In one implementation, please refer to Figure 4 The flow guide 200 is configured as a flow guide pipe.
[0076] The flow guide 200 is tubular and is mainly used to guide the fluid smoothly from one flow guide section 410 to another. The flow guide has a simple structure and is easy to install, which can improve installation efficiency and reduce production costs.
[0077] In one implementation, please refer to Figure 4 The guide component 200 is U-shaped.
[0078] The U-shaped flow guide 200 includes an inlet end, an outlet end, and a connecting portion that connects the two ends, so that fluid enters from the inlet end, passes through the connecting portion, and then flows out from the outlet end. The U-shaped design of the flow guide 200 helps guide the fluid to flow along a predetermined path and reduces the distance between the inlet end and the outlet end, thereby reducing the axial thickness of the first electrode plate 110.
[0079] In other embodiments, the guide member 200 is V-shaped; or the distance between the liquid inlet end and the liquid outlet end gradually decreases in the direction from the connection to the first electrode plate 110.
[0080] In one implementation, please refer to Figure 4 The flow guide 200 is configured as a U-shaped tube.
[0081] In one implementation, please refer to Figure 1 and Figure 3The guide element 200 is set in the middle region of the electrolytic cell in the axial direction.
[0082] In an electrolytic cell system composed of multiple electrode plates 100, the middle electrode plate 100 is often located in a region with a high electric field strength, resulting in a greater bypass current due to temperature effects, mechanical stress, and other factors. The current guide 200 is positioned in the central region of the electrolytic cell along its axial direction to more effectively monitor the bypass current, thereby facilitating targeted measures to optimize or reduce bypass current losses and improve the electrolysis efficiency of the electrolytic cell. Bypass currents also exist in other regions along the axial direction of the electrolytic cell. To comprehensively understand the operating status of the electrolytic cell, current guides 200 and current detectors 300 can be installed in multiple regions along the axial direction of the electrolytic cell, increasing the number of monitoring points.
[0083] In one implementation, please refer to Figures 2 to 4 The electrolytic cell also includes a current detector 300, which is installed on the current guide 200.
[0084] A current detector 300 is installed on the flow guide 200, which can monitor the magnitude of the current flowing through the flow guide 200 in real time. The current detector 300 can be the structure of the flow guide 200 used in this solution, and its shape and installation layout are adapted to the flow guide 200.
[0085] In other embodiments, the current detector 300 may also be an external general-purpose component, not a structure specifically designed for the current guide 200 of this solution, and may come from a different manufacturer than the current guide 200 of this solution.
[0086] In one implementation, please refer to Figures 2 to 4 The current detector 300 is ring-shaped and is sleeved on the outer periphery of the current guide 200.
[0087] The current detector 300 is ring-shaped, forming a closed loop around the flow guide 200. This allows for more accurate detection of the current intensity passing through the flow guide 200, providing more precise data support for control system adjustments and electrolytic cell structure optimization. By directly sleeved on the outside of the flow guide 200, rather than being installed invasively within the fluid flow path, the ring-shaped current detector 300 avoids potential interference or obstruction to fluid flow, reduces the risk of corrosion, and improves operational stability and service life. Furthermore, the external location and sleeved design of the current detector 300 eliminates the need to disassemble the complex internal structure for inspection or replacement, greatly simplifying the installation and maintenance process.
[0088] In other embodiments, the current detector 300 may also be mounted directly or via a mounting bracket to one side of the current guide 200.
[0089] In one embodiment, the current detector 300 is configured as a Hall sensor.
[0090] When fluid flows through the guide member 200, a voltage difference (i.e., Hall voltage) is generated on both sides perpendicular to the current direction and the magnetic field direction. The Hall sensor, with a ring-shaped design, is fitted around the outer periphery of the guide member 200. The Hall sensor can sense changes in the magnetic field generated by the current flowing through the guide member 200, thereby accurately measuring the current intensity through the guide member 200 without interrupting the circuit or altering the existing electrical layout. The Hall sensor provides highly accurate current measurement results, helping to provide more precise data support for the adjustment of the control system and the optimization of the electrolytic cell structure.
[0091] In one embodiment, the Hall sensor is fitted around the outer periphery of the flow guide 200.
[0092] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
