[0031] Since conventional alkaline electrolyzers have a nipple structure on their bipolar plates, their drainage effect is poor, so there will be a dead zone for flow, resulting in poor gas discharge, which in turn causes the gas to pass through the diaphragm and reduce the gas purity.

[0032] In order to improve the problem of flow dead zone, the utility model proposes a pole plate.

[0033] In one embodiment of the present invention, Figure 1 As shown, the electrode plate includes an electrode frame 100 and a partition assembly 200; the electrode frame 100 is provided with an electrolyte inlet 101 and a mixture outlet 102; the partition assembly 200 is installed in the electrode frame 100; a main channel 201 and a plurality of mutually independent branch channels 202 arranged on both sides of the main channel 201 are formed on the partition assembly 200, one end of the main channel 201 is connected to the electrolyte inlet 101, and the other end extends toward the direction close to the mixture outlet 102; one end of the branch channel 202 is connected to the main channel 201, and the other end of the branch channel 202 is connected to the mixture outlet 102, and the branch channel 202 is arranged at an angle to the main channel 201.

[0034] When the separator assembly 200 is installed in the pole frame 100, it can be connected to the pole frame 100 by bonding or welding, thereby reducing the risk of electrolyte leakage. It should be noted that, during the electrolysis process, the electrolysis device usually includes at least two pole plates arranged oppositely, that is, two separator assemblies 200 are arranged oppositely and formed with a gap, so that the gap is an electrolysis chamber. By providing an electrolyte inlet 101 and a mixture outlet 102 on the pole frame 100, the electrolyte enters the electrolysis chamber from the electrolyte inlet 101 to electrolyze and produce gas in the electrolysis chamber, so that the gas is discharged from the mixture outlet 102. A diaphragm can also be provided in the electrolysis chamber, and the diaphragm is usually arranged between each pole plate of the chain to isolate the gases generated on the two pole plates from each other. Usually, the electrolyte inlet 101 is opened at the bottom of the pole frame 100, and the mixture outlet 102 is opened at the top of the pole frame 100, so that the mixture containing gas is convenient to be discharged from the mixture outlet 102.

[0035] A main channel 201 is formed on the partition assembly 200, one end of the main channel 201 is connected to the electrolyte inlet 101, and the other end extends toward the mixture outlet 102; a plurality of independent branch channels 202 are provided on both sides of the main channel 201, the branch channels 202 are arranged at an angle to the main channel 201, and one end of the branch channel 202 is connected to the main channel 201, and the other end is connected to the mixture outlet 102, that is, a flow channel in the shape of a bionic leaf vein is formed on the partition assembly 200, so that the electrolyte flowing out of the electrolyte inlet 101 enters the main channel 201 and is then distributed to the branch channel 202, and then the gas and electrolyte mixture generated after the electrolysis reaction can flow out from the mixture outlet 102. In this technical solution, the arrangement of the main channel 201 and the branch channel 202 provides a good guiding effect for the flow direction of the electrolyte, so that the electrolyte is distributed as evenly as possible on the electrode plate under the drainage effect of the main channel 201 and the branch channel 202, reducing the existence of flow dead zones, reducing the risk of gas passing through the diaphragm, and improving the purity of the gas discharged from the mixture outlet 102. Specifically, the partition assembly 200 includes a main partition 210 arranged in the pole frame 100, and the main channel 201 and the branch channel 202 can be formed by opening a groove on the main partition 210, or by adding a partition. The shape of the main channel 201 can be straight or curved. The shape of the branch channel 202 can be straight or curved.

[0036] The technical solution of the utility model is to set an electrolyte inlet 101 and a mixture outlet 102 on the pole frame 100; the partition assembly 200 is installed in the pole frame 100, and a main channel 201 and a plurality of mutually independent branch channels 202 arranged on both sides of the main channel 201 are formed on the partition assembly 200, one end of the main channel 201 is connected to the electrolyte inlet 101, one end of the branch channel 202 is connected to the main channel 201, and the other end is connected to the mixture outlet 102, then the main channel 201 and the branch channel 202 together form a shape similar to the veins of a leaf, so that the electrolyte flowing out of the electrolyte first enters the main channel 201, and then distributes the electrolyte to each branch channel 202 through the main channel 201, so as to well guide the electrolyte and the gas generated by the electrolysis reaction, reduce the risk of flow dead zone, thereby reducing the risk of gas passing through the diaphragm of the electrolysis device, and improving the gas purity. In the technical solution of the utility model, by connecting one end of the main channel 201 to the electrolyte inlet 101 and extending the other end toward the direction close to the mixture outlet 102, the distance from the partial branch channels 202 located on both sides of the main channel 201 to the mixture outlet 102 can be shortened, thereby avoiding the need to set a long connecting channel between each branch channel 202 and the mixture outlet 102, and reducing the risk of forming a flow dead zone. In addition, such a setting makes the flow channel wall forming the main channel 201 and the flow channel wall forming the branch channel 202 in the partition assembly 200 similar to line contact with the electrodes in the electrolysis device, thereby reducing the contact resistance and improving the current efficiency.

[0037] In the embodiments of the present utility model, please refer to Figure 1 and Figure 2 The partition assembly 200 has two opposite sides, and the electrolyte inlet 101 and the mixture outlet 102 are provided on the opposite sides of the partition assembly 200. The above-mentioned main channel 201 and the above-mentioned branch channel 202 are provided on the opposite sides of the partition assembly 200, wherein the main channel 201 on each side is connected with the electrolyte inlet 101 on the same side, and the end of the branch channel 202 on each side away from the main channel 201 is connected with the mixture outlet 102 on the same side.

[0038] In the electrolysis device, the two opposite sides of the separator assembly 200 in the electrode plate are used to allow the electrolyte to flow and generate gas through electrolysis reaction. An anode electrolysis chamber is formed between one side of the electrode plate and the diaphragm facing the side, and a cathode electrolysis chamber is formed between the other side of the electrode plate and the diaphragm facing the side. Thus, there are an anode reaction electrode and a cathode reaction electrode in the anode electrolysis chamber and the cathode electrolysis chamber respectively. When the electrolysis reaction occurs, oxygen is generated in the anode chamber and hydrogen is generated in the cathode chamber. Therefore, the two opposite sides of the separator assembly 200 are provided with a mixture outlet 102, wherein the side forming the anode chamber is provided with an anode side mixture outlet 1021, and the side forming the cathode chamber is provided with a cathode side mixture outlet 1022.

[0039] By providing the main flow channel 201 and the branch flow channel 202 on opposite sides of the partition assembly 200, the fluids on both sides of the partition assembly 200 can be well guided, avoiding a serious flow dead zone phenomenon on one side, thereby improving the gas purity on each side.

[0040] In the embodiment of the present utility model, Figure 1 As shown, a plurality of branch channels 202 located on the same side of the main channel 201 are arranged in parallel.

[0041] By arranging multiple branch channels 202 on the same side of the main channel 201 in parallel, the guiding direction of the fluid on the same side of the main channel 201 can be consistent, thereby making the fluid distribution on the same side of the main channel 201 more uniform and reducing the generation of flow dead zones.

[0042] Furthermore, the widths of the plurality of branch channels 202 on the same side of the main channel 201 are consistent. This arrangement makes the flow rate to each branch channel 202 average, further reduces the risk of forming a flow dead zone, and improves the purity of the gas.

[0043] Of course, in other embodiments, the multiple branch channels 202 on the same side of the main channel 201 may not be arranged in parallel, but the multiple branch channels 202 on the same side of the main channel 201 gradually converge toward the mixture outlet 102 from close to the main channel 201 to far away from the main channel 201. Such an arrangement not only ensures uniform flow of the fluid, but also has a good guiding effect on the fluid flowing toward the mixture outlet 102.

[0044] In the embodiment of the present utility model, Figure 1 As shown, at least two mixture outlets 102 are provided, and the at least two mixture outlets 102 are symmetrically arranged about the main channel 201. Based on this, the branch channel 202 on one side of the main channel 201 is symmetrically arranged with the branch channel 202 on the other side of the main channel 201.

[0045] By symmetrically arranging the branch channels 202 on both sides of the main channel 201, on the one hand, the flow rate of the fluid on both sides of the main channel 201 can be made equivalent, thereby improving flow uniformity, reducing the risk of poor gas discharge, improving gas purity, and also improving gas discharge efficiency.

[0046] Of course, in other examples, the branch channel 202 on one side of the main channel 201 is staggered with the branch channel 202 on the other side of the main channel 201. It is understandable that such a configuration can still guide the fluid in the main channel 201 to the opposite sides of the main channel 201, and then enter the branch channels 202 on the opposite sides of the main channel 201, which can also improve the flow uniformity of the fluid, reduce the risk of poor gas discharge, and improve the gas purity.

[0047] In the embodiment of the present utility model, Figure 1 As shown, the included angle between the branch channel 202 and the main channel 201 is greater than 0° and less than 90°.

[0048] It should be noted that the angle between the branch channel 201 and the main channel 201 in this embodiment refers to the angle between the flow direction of the fluid in the branch channel 201 and the flow direction of the fluid along the main channel 201, that is, Figure 1 When the included angle between the branch channel 202 and the main channel 201 is greater than 0° and less than 90°, the end of the branch channel 202 away from the main channel 201 can be tilted toward the mixture outlet 102, so that the mixture flowing out of the branch channel 202 can flow to the mixture outlet 102, reducing the risk of flow dead zone on the electrode plate and improving the purity of the gas discharged from the mixture outlet 102.

[0049] In the embodiments of the present utility model, please refer to Figure 1 and Figure 3 The partition assembly 200 includes a main partition 210, a guide plate 220 and a support plate 230. The main partition 210 is installed in the pole frame 100; there are at least two guide plates 220, at least two guide plates 220 are arranged opposite to each other and jointly form a main channel 201, and a plurality of first connecting holes 221 are opened on the guide plate 220, and each branch channel 202 is connected to at least one first connecting hole 221; there are multiple support plates 230 and connected to the guide plates 220 at an angle, and each branch channel 202 is formed by two adjacent support plates 230.

[0050] The main partition 210 can be made of carbon steel and nickel-plated on its surface, so that the main partition 210 can be corrosion-resistant. There are at least two guide plates 220, and at least two guide plates 220 are arranged opposite to each other and form the main channel 201 together, so that the guide plates 220 have a good guiding effect, so that the electrolyte flowing out of the electrolyte inlet 101 can enter the main channel 201 as much as possible, and then be distributed to each branch channel 202 by the main channel 201, reducing the risk that the electrolyte flows directly to both sides after flowing out of the electrolyte inlet 101 and cannot flow into the main channel 201 and then be distributed to the branch channel 202. There can be two guide plates 220, and the two guide plates 220 are arranged opposite to each other. Alternatively, there may be four, six, eight, etc. guide plates 220, which are evenly distributed on both sides, and the guide plates 220 on both sides jointly form the main channel 201. A gap may be provided between two adjacent guide plates 220 on the same side, and the gap may form a connecting gap connected to the branch channel 202; or no gap may be provided between two adjacent guide plates 220 on the same side, but the branch channel 202 is connected through a connecting hole provided on the guide plate 220. The support plate 230 is connected to the guide plate 220 at an angle, and the branch channel 202 formed by the plurality of support plates 230 is also provided at an angle to the main channel 201, so that the effect of distributing the fluid from the main channel 201 to the branch channel 202 can be achieved.

[0051] By arranging the guide plate 220 and the support plate 230 on the main partition plate 210, the situation of opening grooves on the main partition plate 210 can be reduced, thereby avoiding the risk of the main partition plate 210 being too weak. In addition, the guide plate 220, the support plate 230 and the main partition plate 210 are connected to each other, which can simultaneously enhance the strength of any one of the three, and can also make the guide plate 220 and the support plate 230 achieve the effect of line contact with the electrode, thereby reducing resistance and improving current efficiency.

[0052] In an embodiment of the present invention, the cross-sectional shape of the support plate 230 is rectangular, L-shaped, I-shaped or trapezoidal; and / or the cross-sectional shape of the guide plate 220 is rectangular, L-shaped, I-shaped or trapezoidal.

[0053] By setting the cross-sectional shape of the support plate 230 to a rectangular shape, the molding process of the support plate 230 is relatively simple, which is convenient for improving the production efficiency of the plate. By setting the cross-sectional shape of the support plate 230 to an L-shape, an I-shape or a trapezoid, the contact area between the end of the support plate 230 connected to the main separator 210 and the main separator 210 can be larger, thereby improving the support strength and support stability of the support plate 230 and the connection strength between the support plate 230 and the main separator 210.

[0054] By setting the cross-sectional shape of the guide plate 220 to be rectangular, the molding process of the guide plate 220 is relatively simple, which is convenient for improving the production efficiency of the plate. By setting the cross-sectional shape of the guide plate 220 to be L-shaped, I-shaped or trapezoidal, the contact area between the end of the guide plate 220 connected to the main separator 210 and the main separator 210 can be larger, thereby improving the support strength and support stability of the guide plate 220 and the connection strength between the guide plate 220 and the main separator 210.

[0055] In an embodiment of the present invention, the support plate 230 is welded to the main partition plate 210 ; and / or the guide plate 220 is welded to the main partition plate 210 .

[0056] By welding the support plate 230 to the main partition plate 210, the connection strength and stability between the support plate 230 and the main partition plate 210 are improved, and the risk of the support plate 230 easily falling off the main partition plate 210 is avoided. In addition, such a setting also maintains the integrity of the main partition plate 210 and the support plate 230, improves the sealing between the support plate 230 and the main partition plate 210, and reduces the risk of fluid leakage.

[0057] By welding the guide plate 220 to the main partition plate 210, the connection strength and stability between the guide plate 220 and the main partition plate 210 are improved, and the risk of the guide plate 220 easily falling off the main partition plate 210 is avoided. In addition, such a setting also maintains the integrity of the main partition plate 210 and the guide plate 220, improves the sealing between the support plate 230 and the guide plate 220, and reduces the risk of fluid leakage.

[0058] Of course, in other examples, the support plate 230 and the main partition plate 210 may be connected in other ways, such as screw connection or buckle connection, etc. The guide plate 220 and the main partition plate 210 may be connected in other ways, such as screw connection or buckle connection, etc.

[0059] In the embodiment of the present utility model, Figure 1 As shown, one end of the guide plate 220 close to the electrolyte inlet 101 is connected to the pole frame 100 .

[0060] By connecting one end of the guide plate 220 close to the electrolyte inlet 101 to the pole frame 100, the electrolyte flowing out of the electrolyte inlet 101 can directly enter the main channel 201, thereby avoiding the risk that the electrolyte does not enter the main channel 201 but disperses to both sides of the main channel 201, resulting in the inability to be evenly distributed to each branch channel 202 through the main channel 201.

[0061] In the embodiments of the present utility model, please refer to Figure 1 and Figure 2A gap may be provided between the end of the support plate 230 close to the pole frame 100 and the pole frame 100 , thereby ensuring that the end of the branch channel 202 away from the main channel 201 can be connected to the mixture outlet 102 through the gap.

[0062] In the embodiments of the present utility model, please refer to Figure 1 , Figure 4 as well as Figure 5 An enclosure plate 240 is provided at one end of the main channel 201 away from the electrolyte inlet 101 , and a second connecting hole 241 is provided on the enclosure plate 240 . Both sides of the second connecting hole 241 are connected to the main channel 201 and the mixture outlet 102 , respectively.

[0063] By providing an enclosure plate 240 at one end of the main channel 201 away from the electrolyte inlet 101, it is possible to reduce the amount of larger debris flowing from the main channel 201 to the mixture outlet 102. By providing a second connecting hole 241 on the enclosure plate 240, the two sides of the second connecting hole 241 are connected to the main channel 201 and the mixture outlet 102 respectively, so that the mixture of gas and liquid in the main channel 201 can flow to the mixture outlet 102 through the second connecting hole 241, thereby preventing the mixture from remaining in the main channel 201.

[0064] The utility model also proposes an electrolysis device, which includes an electrode plate. The specific structure of the electrode plate refers to the above embodiment.
