Therefore, on the one hand, the electrolysis efficiency will decrease. On the other hand, as the reaction proceeds, the area with less electrolyte distribution will corrode or even burn through the diaphragm, affecting the life and safety of the electrolyzer.

[0033] The utility model provides an electrolytic cell electrode plate 100.
[0034] In the technical solution of this utility model, please refer to Figure 1 and Figure 4 The electrolytic cell plate 100 includes a plate body 110 and a distribution pipe 120. The plate body 110 has an inlet end 1101 and an outlet end 110b. The plate body 110 has an over-temperature region 111. The over-temperature region 111 is set away from the flow path of the electrolyte from the inlet end 1101 to the outlet end 110b; one end of the distribution pipe 120 is connected to the inlet end 1101, and the other end extends to the over-temperature region 111, and a diversion hole 121a is opened at the end of the distribution pipe 120 extending to the over-temperature region 111.
[0035] In the actual electrolysis process, the electrolytic cell plates 100 in the electrolysis device are usually provided with at least two, and the plate bodies 110 of the two electrolytic cell plates 100 are separated by the diaphragm 300, and the electrolysis chamber 10 is formed between the diaphragm 300 and the two electrolytic cell plates 100. It can be understood that an anode electrolysis chamber 10 is formed between one of the electrolytic cell plates 100 and the diaphragm 300, and a cathode electrolysis chamber 10 is formed between the other electrolytic cell plate 100 and the diaphragm 300, so that there are anode reaction electrodes and cathode reaction electrodes in the anode electrolysis chamber 10 and the cathode electrolysis chamber 10 respectively, and when the electrolysis reaction occurs, oxygen is generated in the anode chamber and hydrogen is generated in the cathode chamber. The plate body 110 in the electrolytic cell plate 100 in the technical solution of the utility model has an inlet end 1101 and an outlet end 110b, so that the electrolyte can enter from the inlet end 1101 of the plate body 110, and the electrolyte flows along the plate surface of the plate body 110 to enter the electrolysis chamber 10, and generates gas after the electrolysis reaction occurs in the electrolysis chamber 10, and the gas can flow out from the outlet end 110b. Generally, the plate body 110 is placed vertically, the inlet end 1101 of the plate body 110 is set at the bottom end of the plate body 110, and the outlet end 110b of the plate body 110 is set at the top end of the plate body 110, so that the gas can flow out from the outlet end 110b.
[0036] It is understandable that when the electrolyte flows along the plate surface of the electrode body 110 after entering from the inlet end 1101, it generally flows along a path closer to the outlet end 110b. Figure 1 When the middle plate body 110 is provided with two inlet ports 1101 at the bottom and an outlet port 110b at the top, the outlet port 110b at the top is arranged close to the left side, so when the electrolyte flows on the plate body 110, it usually flows to the left and downward, that is, the electrolyte is easy to flow in a similar triangular area (defined as a self-flowing area) formed by the line connecting the two inlet ports 1101 and one outlet port 110b, but not easy to flow to the area on the upper right side of the plate body 110 or the area close to the middle of the left edge. Therefore, when the size of the electrolytic cell plate 100 is large, the area of the plate body 110 that deviates from the flow path from the inlet port 1101 to the outlet port 110b will become an electrolyte dead zone, that is, an over-temperature area 111. Since there is no electrolyte replenishment in the over-temperature area 111, the over-temperature area 111 will easily experience high temperature and corrosion, and even burn through the diaphragm 300. In the technical solution of the present utility model, a distribution pipe 120 is provided, and one end of the distribution pipe 120 is connected to the inlet end 1101, and the other end extends to the over-temperature area 111, so that a certain amount of electrolyte can also be distributed to the over-temperature area 111, thereby increasing the actual reaction area, and then achieving the effect of increasing the gas production; in addition, such a setting also avoids the risk of high temperature and corrosion in the over-temperature area 111 due to the presence of electrolyte, thereby reducing the risk of burning through the diaphragm 300 and improving the life and safety performance of the electrolytic cell.
[0037] Specifically, the distribution pipe 120 can be a tube structure independent of the electrode body 110, or a channel structure formed on the electrode body 110; the distribution pipe 120 can be a straight pipe or a curved pipe. As long as the distribution pipe 120 can forcibly distribute part of the electrolyte at the inlet end 1101 to the over-temperature area 111.
[0038] The technical solution of the utility model is to set an inlet end 1101 and an outlet end 110b on the electrode body 110, so that the electrolyte can enter from the inlet end 1101 and flow along the plate surface of the electrode body 110 to the electrolysis chamber 10 to perform an electrolysis reaction, so that the gas generated after the reaction can flow out from the outlet end 110b. Further, the electrode body 110 has an over-temperature area 111 set to deviate from the flow path of the electrolyte from the inlet end 1101 to the outlet end 110b. By connecting one end of the distribution pipe 120 to the inlet end 1101 and extending the other end to the over-temperature area 111, the distribution pipe 120 can force the distribution of part of the electrolyte entering from the inlet end 1101 to the over-temperature area 111, thereby improving the problem of less electrolyte in the over-temperature area 111, so as to further improve the phenomenon of uneven distribution of electrolyte on the electrolytic cell electrode plate 100. With such a configuration, the actual reaction area can be increased, and then the gas production can be increased. In addition, such a configuration can also prevent the over-temperature region 111 from being overheated, reduce the risk of corrosion of the over-temperature region 111 and the risk of burning through the diaphragm 300, and improve the service life and safety performance of the electrolytic cell plate 100.
[0039] Further, please refer to Figure 1 and Figure 3 At least two flow diversion holes 121 a are formed on the wall of one end of the distribution pipe 120 extending to the over-temperature region 111 .
[0040] By providing at least two diverter holes 121a in the pipe wall of one end of the distribution pipe 120 extending to the over-temperature region 111, the efficiency of the electrolyte in the distribution pipe 120 flowing to the over-temperature region 111 can be improved; in addition, the electrolyte spraying range can be increased, so that the electrolyte in the over-temperature region 111 is more evenly distributed. Specifically, the shape of the diverter hole 121a can be circular, rectangular or other shapes.
[0041] It is understood that, in this embodiment, the diverter hole 121a is formed on the wall of the distribution tube 120, and the center line of the diverter hole 121a is perpendicular to the length direction of the distribution tube 120. In another example, the end surface of the distribution tube 120 may also be provided with an opening, so that the electrolyte can also flow out along the length direction of the distribution tube 120.
[0042] In one example, the distribution pipe 120 is a hose, and the electrolytic cell plate 100 further includes a fixing member, and the distribution pipe 120 is fixed to the plate body 110 through the fixing member.
[0043] By setting the distribution pipe 120 as a hose, the hose can be flexibly directed to different positions, so that the direction of the hose can be more flexibly adjusted so that the hose can be more accurately directed to the overtemperature area 111. Specifically, the hose can be made of polytetrafluoroethylene or other materials that can resist electrolyte corrosion.
[0044] It is understandable that when the distribution pipe 120 is a hose, and after the distribution pipe 120 has been adjusted to the end away from the inlet end 1101 and extends to the over-temperature area 111, the distribution pipe 120 can also be fixed to the plate body 110 by a fixing member. The fixing member can be a fixing clip or a fixing clamp, etc. For example, when the fixing member is a fixing clip, the fixing clip can be bonded to the plate body 110, and the fixing clip has a bayonet, and the size of the bayonet can be set to be slightly smaller than the diameter of the distribution pipe 120, so that the distribution pipe 120 passes through the bayonet to be clamped into the fixing clip. Of course, in other examples, the fixing member can also be an adhesive, a welding material, etc.
[0045] Alternatively, in another example, the dispensing tube 120 is a rigid tube.
[0046] By setting the distribution pipe 120 as a hard pipe, the shape of the distribution pipe 120 is not easily changed after extending to the over-temperature area 111, thereby reducing the installation steps of fixing by the fixing member. Of course, in order to further ensure the stability of the distribution pipe 120, the distribution pipe 120 can be directly welded or bonded to the electrode body 110, or can also be fixed to the electrode body 110 by the above-mentioned fixing member. Specifically, when the distribution pipe 120 is a hard pipe, the material of the distribution pipe 120 can be pure nickel or a nickel-based alloy material, so as to be able to resist the corrosion of the electrolyte.
[0047] In one example, the distribution pipe 120 is a flow channel formed by a depression on the plate surface of the electrode body 110 .
[0048] By setting the distribution pipe 120 as a flow channel formed by the depression of the plate surface of the electrode body 110, the installation steps of the distribution pipe 120 and the electrode body 110 can be reduced. It can be understood that in order to ensure that the distribution pipe 120 can extend to the over-temperature area 111 more accurately, before the flow channel used as the distribution pipe 120 is opened on the electrode body 110, the actual operating conditions of the electrolytic cell electrode plate 100 can be simulated first, so as to pre-identify the over-temperature area 111 during electrolysis, and then determine the position of the distribution pipe 120 away from the inlet end 1101 according to the identified over-temperature area 111, and then determine the connection trajectory between the inlet end 1101 and the determined inlet end 1101 according to the position of the inlet end 1101, so as to accurately form the flow channel as the distribution pipe 120 in the depression of the plate surface of the substrate body.
[0049] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4The inlet end 1101 includes a liquid inlet 1101a and a flow groove 1101b. The liquid inlet 1101a is opened at the edge of the electrode body 110; the flow groove 1101b is opened on the plate surface of the electrode body 110 and is connected with the liquid inlet 1101a. One end of the distribution pipe 120 is installed in the flow groove 1101b and is connected with the flow groove 1101b.
[0050] The electrode plate body 110 may include a plate body and an outer frame, wherein the outer frame is formed with a mounting opening, and the plate body may be mounted in the mounting opening of the outer frame. By opening the liquid inlet 1101a at the edge of the electrode plate body 110, the liquid inlet 1101a may be located on the outer frame, so that the electrolyte may flow to the plate body through the liquid inlet 1101a and fill the plate body, thereby increasing the actual reaction area of the plate body and thereby increasing the gas production.
[0051] In addition, it is understood that when the electrolytic cell plate 100 is used in an electrolysis device, the electrolytic cell plate 100 is sometimes arranged in abutment with the adjacent pole net 200 to reduce the inter-pole distance between the electrolytic cell plate 100 and the adjacent pole net 200, increase the current density of the electrolysis chamber 10, and improve the efficiency of the hydrogen production reaction. In this embodiment, by providing the flow slot 1101b, the bottom wall of the flow slot 1101b can be prevented from being in abutment with the adjacent pole net 200, thereby facilitating the electrolyte to flow smoothly into the electrolysis chamber 10 through the flow slot 1101b. If the flow slot 1101b is not provided, there may be a risk that the electrolyte cannot flow into the electrolysis chamber 10 formed between the plate body 110 and the diaphragm 300 after flowing out from the liquid inlet 1101a due to the contact between the pole net 200 and the electrolytic cell plate 100.
[0052] By installing one end of the distribution pipe 120 in the circulation groove 1101b and communicating with the circulation groove 1101b, part of the electrolyte in the circulation groove 1101b can flow into the distribution pipe 120, and then the distribution pipe 120 can be used to guide the electrolyte to the over-temperature area 111, thereby avoiding the situation where there is too little electrolyte in the over-temperature area 111. Specifically, the distribution pipe 120 can be fixed in the circulation groove 1101b by welding or bonding, so as to ensure that part of the electrolyte can flow smoothly into the distribution pipe 120.
[0053] Further, in one embodiment, please refer to Figure 1 and Figure 2 The distribution pipe 120 includes a pipe body 121 and an adapter 122. One end of the pipe body 121 extends into the over-temperature area 111, and the other end of the pipe body 121 is close to the circulation groove 1101b; the adapter 122 is detachably connected and communicated with one end of the pipe body 121 close to the circulation groove 1101b, and the adapter 122 is installed in the circulation groove 1101b and communicated with the circulation groove 1101b.
[0054] The tube body 121 refers to a pipeline for electrolyte to flow to the over-temperature area 111. The adapter 122 refers to an adapter for introducing the electrolyte in the flow slot 1101b into the tube body 121. By providing an adapter 122 that is detachably connected to one end of the tube body 121 close to the flow slot 1101b, the cross section of the tube body 121 can be set to a shape different from the shape of the notch of the flow slot 1101b, and the adapter 122 is used for the connection, so as to facilitate the mass production of the tube body 121 or the flexible selection of the tube body 121. The port shape of the end of the adapter 122 away from the tube body 121 can be set to the same shape as the notch of the flow channel slot, so as to facilitate the adapter 122 to be adapted and installed in the flow slot 1101b. The port shape of the end of the adapter 122 connected to the tube body 121 can be the same as the shape of the tube body 121, so that the adapter 122 can be adapted and installed with the tube body 121, thereby improving the sealing of the connection between the adapter 122 and the tube body 121. For example, when the cross section of the tube body 121 is circular and the notch shape of the circulation groove 1101b is rectangular, the tube opening of the adapter 122 used to be installed to the end of the circulation groove 1101b is set to be rectangular, and the tube opening of the end of the adapter 122 used to be connected to the tube body 121 is circular. Alternatively, when the cross section of the tube body 121 is rectangular and the notch shape of the circulation groove 1101b is circular, the tube opening of the adapter 122 used to be installed to the end of the circulation groove 1101b is set to be circular, and the tube opening of the end of the adapter 122 used to be connected to the tube body 121 is rectangular.
[0055] Furthermore, the total area of the inlet cross sections of the adapters 122 is S1, the total area of the slots of the flow slots 1101b is S2, the area of the over-temperature region 111 is S3, the total area of the plate surface of the plate body 110 is S4, and the value of S1 / S2 is positively correlated with the value of S3 / S4.
[0056] It should be noted that when there is one adapter 122, the total area of the inlet cross-sections of the adapters 122 is the area of the inlet cross-section of the adapter 122. When the over-temperature area 111 is large or the number of over-temperature areas 111 is large, at least two distribution pipes 120 may be required, and at this time at least two adapters 122 are also required. When there are at least two adapters 122, the total area of the inlet cross-sections of the adapters 122 is the sum of the areas of the inlet cross-sections of all adapters 122. When there is one circulation slot 1101b, the total area of the slots of the circulation slots 1101b is the slot area of the circulation slot 1101b; when there are at least two circulation slots 1101b, the total area of the slots of the circulation slots 1101b is the sum of the slot areas of all circulation slots 1101b. The total plate surface area of the electrode body 110 refers to the total plate surface area of the electrode body 110 corresponding to the above-mentioned over-temperature area 111, that is, the sum of the areas of the above-mentioned self-flow area and the over-temperature area 111 on a single side of the plate surface, and does not refer to the sum of the two opposite plate surface areas of the electrode body 110.
[0057] By setting the ratio of the total area S1 of the inlet cross-sections of the plurality of adapters 122 to the total area S2 of the slots of the plurality of flow slots 1101b to be positively correlated with the ratio of the area S3 of the over-temperature region 111 to the total area S4 of the plate surface of the electrode body 110, the distribution pipe 120 can distribute the electrolyte to the over-temperature region 111 in an appropriate proportion, thereby ensuring that the volume of the electrolyte in the over-temperature region 111 and the electrolyte in other regions are relatively equal.
[0058] Further, please refer to Figure 1 and Figure 2 The dimension of the distribution pipe 120 in the direction perpendicular to the plate surface of the electrode body 110 is H1, and the dimension of the flow groove 1101b in the direction perpendicular to the plate surface of the electrode body 110 is H2, 1 / 3≤H1 / H2≤2 / 3.
[0059] In the direction perpendicular to the plate surface of the electrode body 110, that is, the height direction of the electrolysis chamber 10, by setting the dimension of the distribution pipe 120 in the direction perpendicular to the plate surface of the electrode body 110 to H1, and the dimension of the flow slot 1101b in the direction perpendicular to the plate surface of the electrode body 110 to H2, and 1 / 3≤H1 / H2≤2 / 3, on the one hand, the diameter of the distribution pipe 120 will not be too small, resulting in the risk of electrolyte being difficult to flow to the distribution pipe 120 or the proportion of electrolyte flowing to the distribution pipe 120 being too small; on the other hand, such a setting will not cause the diameter of the distribution pipe 120 to be too large and abut against the adjacent electrode network 200, thereby avoiding the risk of current flowing along the distribution pipe 120 and reducing the current efficiency. Specifically, the value of H1 / H2 can be 1 / 3, 1 / 2 or 2 / 3, etc.
[0060] Furthermore, if Figure 1 As shown, a protruding structure 130 is protruded on the plate surface of the electrode body 110 to support the electrode net 200 .
[0061] By providing a protruding structure 130 on the plate surface of the electrode body 110, the distance between the electrode body 110 and the adjacent electrode net 200 can be reduced. When the protruding structure 130 is used to support the electrode net 200, the protruding structure 130 can be fitted with the adjacent electrode net 200, thereby reducing the electrode distance between the electrolytic cell electrode 100 and the adjacent electrode net 200, increasing the current density of the electrolysis chamber 10, and improving the hydrogen production reaction efficiency.
[0062] Specifically, when the electrode nets 200 are provided on both opposite sides of the electrode plate body 110, the two opposite plate surfaces of the electrode plate body 110 may be provided with protruding structures 130, so that the protruding structures 130 provided on the two plate surfaces respectively support different electrode nets 200. Based on this situation, the above-mentioned liquid inlet 1101a can be set as a through-hole that passes through the two opposite plate surfaces of the electrode plate body 110. Correspondingly, the flow groove 1101b can be provided on the two opposite plate surfaces of the electrode plate body 110, so that the electrolyte passing through the liquid inlet 1101a can flow from the flow grooves 1101b on the two opposite plate surfaces of the electrode plate body 110 to different electrolysis chambers 10 at the same time. Correspondingly, the outlet end 110b can also be provided through the two opposite plate surfaces of the electrode plate body 110. Specifically, when the flow slots 1101b are provided on two opposite plate surfaces of the electrode body 110, the flow slots 1101b on the two plate surfaces may be symmetrically arranged with respect to the electrode body 110, or the flow slots 1101b on the two plate surfaces may not be arranged symmetrically with respect to the electrode body 110. In addition, the gas generated on the opposite sides of the electrode body 110 may flow out through the same outlet end 110b, or may not flow out through the same outlet end 110b.
[0063] The present invention also provides an electrolysis device, please refer to Figure 1 and Figure 4 The electrolysis device includes an electrolytic cell plate 100, and the specific structure of the electrolytic cell plate 100 refers to the above embodiment.
