[0027] In the related art, the performance of the membrane electrode in the electrolytic hydrogen and oxygen production equipment gradually decays with the service cycle. Therefore, during the daily maintenance of the electrolytic hydrogen and oxygen production equipment, it is necessary to monitor the potentials of the cathode and the anode, and understand the decay situation of the membrane electrode through the monitoring results, and then maintain or replace the membrane electrode. In order to decouple the potential changes of the cathode and the anode from the overall membrane electrode, usually, a standard reference electrode is set in the electrolytic cell for potential monitoring. By using the standard reference electrode and the measured electrode for measurement, a relatively accurate monitoring result can be obtained without damaging the structure of the membrane electrode. However, the price of the standard reference electrode is high, and using the method of setting a standard reference electrode will result in a high production cost of the electrolytic hydrogen and oxygen production equipment; and it needs to be used in an environment of high-purity hydrogen during the monitoring process, resulting in a certain danger in the monitoring experiment, reducing the practicability and reliability of the electrolytic hydrogen and oxygen production equipment. To solve the above problems, the present application proposes a membrane electrode 100.
[0028] Please refer to Figures 1 to 4 , in an embodiment of the present application, the membrane electrode 100 includes a proton exchange membrane 10, a catalytic assembly, and a monitoring assembly 70. It is defined that the proton exchange membrane 10 has two opposite mounting surfaces; the catalytic assembly includes a first catalytic layer 30 and a second catalytic layer 50. The first catalytic layer 30 is attached to one mounting surface, and the second catalytic layer 50 is attached to the other mounting surface; the monitoring assembly 70 is disposed on any one of the mounting surfaces. The monitoring assembly 70 includes a test pole wire 71 and an isolation membrane 73. The test pole wire 71 is disposed on the mounting surface, and the isolation membrane 73 is attached to the mounting surface and covers the test pole wire 71.
[0029] It can be understood that the electrolytic hydrogen and oxygen production equipment can pass an electric current through the electrolytic solution in the electrolytic cell to decompose the electrolytic solution under the action of electric energy to produce hydrogen and oxygen. At this time, the collection device can be used to purify and collect the generated hydrogen and oxygen respectively to ensure the stable and reliable operation of the electrolytic hydrogen and oxygen production equipment. Among them, a plurality of membrane electrodes 100 can be stacked in the electrolytic cell, so that each membrane electrode 100 can form a relatively independent electrolytic chamber, and then the electrolytic reaction rate in the electrolytic cell can be better improved under the action of the proton exchange membrane 10 and the catalytic structure of the membrane electrode 100, and the working efficiency of the electrolytic hydrogen and oxygen production equipment can be further improved.
[0030] In this embodiment, the two mounting surfaces of the proton exchange membrane 10 can be respectively arranged close to the cathode electrode and the anode electrode. By attaching the first catalytic layer 30 and the second catalytic layer 50 of the catalytic structure to the two mounting surfaces of the proton exchange membrane 10 respectively, the first catalytic layer 30 can be made of a substance that promotes the electrolytic hydrogen evolution reaction, and the first catalytic layer 30 can be arranged close to the cathode electrode of the electrolytic cell, so that the hydrogen production efficiency of the electrolytic hydrogen and oxygen production equipment can be better improved under the action of the first catalytic layer 30; in addition, the second catalytic layer 50 can be made of a substance that promotes the electrolytic oxygen evolution reaction, and the second catalytic layer 50 can be arranged close to the anode electrode of the electrolytic cell, so that the oxygen production efficiency of the electrolytic hydrogen and oxygen production equipment can be better improved under the action of the second catalytic layer 50. Among them, the proton exchange membrane 10 can play a role in separating the cathode electrode and the anode electrode in the electrolytic cell, and the proton exchange membrane 10 can be used to conduct protons, so that the electrolytically generated hydrogen ions can move to the cathode electrode through the proton exchange membrane 10 better to react to generate hydrogen, ensuring the stable and efficient progress of the electrolytic reaction.
[0031] By arranging a monitoring component 70 on the mounting surface of the proton exchange membrane 10, it can be arranged on the mounting surface of the proton exchange membrane 10 close to the cathode electrode, or it can be arranged on the mounting surface of the proton exchange membrane 10 close to the anode electrode, so that the monitoring component 70 can be in an environment of hydrogen protons. Then, by using a monitoring instrument to measure the potential of the monitoring component 70, the standard hydrogen electrode potential can be obtained, which is beneficial to comparing the monitored standard hydrogen electrode potential with the cathode and anode potentials on both sides of the membrane electrode 100 to achieve the performance detection of the membrane electrode 100. The monitoring component 70 can be embedded in the mounting surface of the proton exchange membrane 10 by using a test pole wire 71. At this time, the test pole wire 71 can be pressed and embedded in the mounting surface by using a hot pressing technique, or a groove with a size matching the test pole wire 71 can be preset on the mounting surface, so that the test pole wire 71 can be stably installed in the groove and abut against the inner wall of the groove, so that the test pole wire 71 can be better attached to the mounting surface, so that the hydrogen protons on the proton exchange membrane 10 can be stably attached to the test pole wire 71, ensuring that a stable standard hydrogen electrode potential can be monitored from the test pole wire 71. By attaching an isolation membrane 73 to the mounting surface, the isolation membrane 73 can be used to wrap and cover the test pole wire 71. The isolation membrane 73 can be made of a material that is insulating but can conduct hydrogen protons. Under the action of the isolation membrane 73, the influence of the electrolyte and the catalytic structure on the test pole wire 71 can be stably isolated, so that the test pole wire 71 can stably obtain the potential of hydrogen protons, ensuring the detection accuracy and reliability of the membrane electrode 100; and it can make hydrogen protons stably pass through the isolation membrane 73 and the proton exchange membrane 10 and conduct to the cathode electrode for reduction, which is beneficial to better ensuring the performance stability of the membrane electrode 100, reducing the damage and influence on the structure of the membrane electrode 100, and effectively improving the overall structural stability and reliability of the membrane electrode 100.
[0032] The technical solution of this application can enable the test electrode wire 71 of the monitoring component 70 to be embedded in the installation surface by arranging the monitoring component 70 on any installation surface of the proton exchange membrane 10, and covering the test electrode wire 71 with the isolation membrane 73 can well isolate the test electrode wire 71 from the catalytic structure and the electrolytic solution, so that the test electrode wire 71 can better adhere to hydrogen protons. Furthermore, connecting the test electrode wire 71 with a test instrument can stably measure the standard hydrogen electrode potential on the membrane electrode 100, which is beneficial to comparing this standard potential with the electrode potential in the electrolytic cell and understanding the performance of the membrane electrode 100 according to the comparison result, so as to maintain or replace the membrane electrode 100 and ensure the stable operation of the electrolytic hydrogen and oxygen production equipment. Covering and isolating the test electrode wire 71 with the isolation membrane 73 on the installation surface of the proton exchange membrane 10 can more conveniently obtain the standard test potential by using the proton exchange membrane 10, without setting an expensive standard reference electrode to measure the standard potential, effectively reducing the production cost of the electrolytic cell; at the same time, it can reduce the adjustment of the overall structure of the membrane electrode 100, which is beneficial to better ensuring the performance stability of the membrane electrode 100 and further improving the practicability and reliability of the membrane electrode 100.
[0033] In the embodiment of this application, the thickness of the isolation membrane 73 is defined as W, and 0.001 mm ≤ W ≤ 1 mm.
[0034] In this embodiment, by limiting the thickness of the isolation membrane 73 attached to the proton exchange membrane 10 to be in the range of 0.001 mm to 1 mm, the isolation membrane 73 can stably cover the test electrode wire 71, avoiding the influence of the test electrode wire 71 by the catalytic structure or the electrolytic solution; and the thickness of the isolation membrane 73 can be effectively reduced, reducing the overall thickness of the membrane electrode 100. Among them, by making the thickness of the isolation membrane 73 greater than or equal to 0.001 mm, the isolation membrane 73 can better fill and cover the partial structure of the test electrode wire 71 exposed on the installation surface, realizing reliable sealing and isolation of the test electrode wire 71, effectively reducing the influence of other factors on the test electrode wire 71, and ensuring that the test electrode wire 71 can stably measure the standard hydrogen electrode potential; at the same time, by making the thickness of the isolation membrane 73 less than or equal to 1 mm, within this range, the isolation membrane 73 can be set with a smaller thickness size while covering the test electrode wire 71, which is beneficial to better reducing the overall thickness size of the membrane electrode 100, and further better reducing the influence of the monitoring component 70 on the overall structure size of the membrane electrode 100, so that the membrane electrode 100 can maintain better overall performance, and further improving the structural stability and reliability of the membrane electrode 100.
[0035] Refer to Figure 4 In the embodiment of this application, the installation surface forms a limiting groove 11, and the isolation membrane 73 is arranged in the limiting groove 11.
[0036] In this embodiment, by forming a limiting groove 11 on the mounting surface of the proton exchange membrane 10, the size of the limiting groove 11 can be set corresponding to the size of the isolation membrane 73, so that the membrane electrode 100 can embed the test electrode wire 71 on the bottom wall of the limiting groove 11 and place the isolation membrane 73 in the limiting groove 11 to realize the installation of the monitoring component 70 on the membrane electrode 100. Under the action of the limiting groove 11 accommodating the isolation membrane 73, the exposed part of the monitoring component 70 on the mounting surface can be better reduced, which is beneficial to better avoid the increase in the overall thickness dimension of the membrane electrode 100, so that the membrane electrode 100 can maintain a more stable performance setting, and further improve the structural stability and reliability of the membrane electrode 100.
[0037] Among them, after the test electrode wire 71 and the isolation membrane 73 are installed on the mounting surface of the proton exchange membrane 10, the membrane electrode 100 can form the limiting groove 11 by pressing the isolation membrane 73 on the mounting surface through a pressing technique; or, the limiting groove 11 can be preset during the production process of the proton exchange membrane 10, and then during the installation process of the membrane electrode 100, the isolation membrane 73 can be installed and fixed corresponding to the limiting groove 11, or a liquid isolation membrane 73 solution can be sprayed or poured into the limiting groove 11 to solidify and form the isolation membrane 73.
[0038] In the embodiment of the present application, the material of the isolation membrane 73 is resin.
[0039] In this embodiment, the isolation membrane 73 can be made of a curable resin material. At this time, after the test electrode wire 71 is installed on the mounting surface, the resin solution can be sprayed on the mounting surface corresponding to the position of the test electrode wire 71 by using a spray gun, so that the resin solution solidifies to form the isolation membrane 73 to more stably cover the test electrode wire 71, so that the isolation membrane 73 can further fill the gap between the test electrode wire 71 and the proton exchange membrane 10, achieving a better isolation and protection effect on the test electrode wire 71. By using the isolation membrane 73 made of resin, the isolation membrane 73 can be more conveniently installed and attached to the proton exchange membrane 10 to achieve a better covering effect on the test electrode wire 71; at the same time, the proton-conducting property of the resin can be used to better ensure that the hydrogen protons conducted on the proton exchange membrane 10 can pass through the isolation membrane 73. The influence of the monitoring component 70 on the proton exchange membrane 10 is better reduced, so that the membrane electrode 100 can maintain good performance during use, and the practicality and reliability of the membrane electrode 100 are further improved.
[0040] Refer to Figure 1 and Figure 2 In the embodiment of the present application, the test electrode wire 71 includes a wiring section 711 and a receiving section 713. The receiving section 713 is connected to the wiring section 711. The receiving section 713 is embedded in the mounting surface, and at least two bending structures are formed on the receiving section 713.
[0041] In this embodiment, the test pole wire 71 connects the wiring section 711 exposed outside the proton exchange membrane 10 to a test instrument, so that the test instrument can obtain the standard hydrogen electrode potential of the hydrogen protons attached to the accommodation section 713 through the wiring section 711, ensuring the accuracy and reliability of the detection results. Among them, by bending the accommodation section 713 embedded in the installation surface to form at least two bending structures, the accommodation section 713 of the test pole wire 71 can be meanderingly arranged on the installation surface of the proton exchange membrane 10, which is beneficial to better increasing the length of the test pole wire 71 embedded in the proton exchange membrane 10, increasing the contact area between the test pole wire 71 and the proton exchange membrane 10, enabling the test pole wire 71 to better attach to the hydrogen protons conducting inside the proton exchange membrane 10, further improving the accuracy and reliability of the standard hydrogen electrode potential obtained through the test pole wire 71, and further improving the practicability and reliability of the membrane electrode 100.
[0042] Refer to Figure 3 and Figure 4 , in the embodiment of the present application, a wire groove 13 is provided on the installation surface, and the test pole wire 71 is arranged in the wire groove 13 and abuts against the inner wall of the groove of the wire groove 13.
[0043] In this embodiment, by providing the wire groove 13 on the installation surface, the size of the wire groove 13 can be set corresponding to the size of the test pole wire 71, so that the test pole wire 71 can be installed and fixed in the wire groove 13, ensuring the stable contact between the test pole wire 71 and the proton exchange membrane 10, enabling the hydrogen protons to stably attach to the test pole wire 71 so that the monitoring component 70 can stably measure a relatively accurate standard hydrogen electrode potential; at the same time, under the action of the wire groove 13, the limit fixation of the test pole wire 71 can be realized, which is beneficial to better avoiding the relative movement between the test pole wire 71 and the proton exchange membrane 10 during transportation or use, preventing the test pole wire 71 from detaching from the proton exchange membrane 10, and further improving the structural stability and reliability of the membrane electrode 100.
[0044] Among them, the membrane electrode 100 can use a hot pressing device to press the test pole wire 71 on the installation surface to form the wire groove 13, or, the wire groove 13 can be preset corresponding to the size of the test pole wire 71 during the production process of the proton exchange membrane 10, so that the test pole wire 71 can be installed corresponding to the wire groove 13 during the assembly process of the membrane electrode 100, ensuring the stable installation of the test pole wire 71 on the proton exchange membrane 10.
[0045] In the embodiment of the present application, the material of the test pole wire 71 is platinum wire.
[0046] In this embodiment, the test pole wire 71 can be made of platinum wire. By utilizing the property of platinum wire to enrich hydrogen protons, the test pole wire 71 can better attach hydrogen protons in the hydrogen proton-rich environment of the proton exchange membrane 10. And through the electrical connection between the test instrument and the test pole wire 71, the standard hydrogen electrode potential can be obtained more stably, ensuring the accuracy of the monitoring result of the membrane electrode 100 and further improving the practicability and reliability of the membrane electrode 100.
[0047] Refer to Figure 1 , in the embodiment of the present application, two mounting surfaces are defined as the first mounting surface and the second mounting surface respectively.

Among them, the monitoring component 70 can embed the test electrode and / or the isolation membrane 73 on the first mounting surface, which is beneficial to better reducing the structural protrusion of the monitoring component 70 on the first mounting surface and reducing the influence of the monitoring component 70 on the overall thickness dimension of the membrane electrode 100, ensuring the stability of the overall performance of the membrane electrode 100.
