[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides an implementation scheme: In the current flow battery stack, the ion exchange membrane is usually arranged between a pair of electrodes. In order to fix the ion exchange membrane, a sealing frame is usually set on the electrode. However, since the sealing frame is mostly integrated with the electrode, the ion exchange membrane is often thin, and the size of the sealing frame is larger than the ion membrane, the installation is inconvenient and the problem of ion exchange membrane misalignment is easy to occur.

[0023] To address the aforementioned issues, this application discloses an ion exchange membrane structure, including a main membrane 1, which is a rectangular ion exchange membrane. The main membrane 1 serves as a two-sided ion exchange membrane. A fixing plate 2 is provided on the outside of the main membrane 1. The fixing plate 2 is a rectangular silicone U-shaped plate. After the main membrane 1 is cut, the fixing plate 2 is installed on the outside of the main membrane 1 by heat fusion or adhesive bonding. The fixing plate 2 allows for faster installation of the main membrane 1.

[0024] According to the instruction manual Figures 1-3 It can be seen that a pair of reinforcing sealing plates 3 are provided on the above-mentioned fixing plate 2. The pair of reinforcing sealing plates 3 are arranged around the outer edge of the fixing plate 2. The fixing plate 2 is fixed by the pair of reinforcing sealing plates 3. A pair of limiting grooves 4 are provided on the inner side of the pair of reinforcing sealing plates 3 to close the two sides of the fixing plate 2. During the installation process, the pair of reinforcing sealing plates 3 are fixed with a pair of electrodes on both sides. The fixing effect of the main body membrane 1 is achieved by the mutual locking of the pair of reinforcing sealing plates 3 and the fixing plate 2. Since the size of the fixing plate 2 is larger and thicker than the main body membrane 1, it can be easily picked up and placed between the pair of limiting grooves 4 of the pair of reinforcing sealing plates 3.

[0025] Furthermore, several pairs of fixing rods 5 are symmetrically arranged on both sides of the aforementioned reinforced sealing plate 3, and several pairs of fixing slots 6 are symmetrically arranged on adjacent sides of the reinforced sealing plate 3. The fixing slots 6 are correspondingly arranged with the fixing rods 5. By using the relative arrangement of a pair of reinforced sealing plates 3, the fixing rods 5 of one reinforced sealing plate 3 correspond to the fixing slots 6 of the other reinforced sealing plate 3, so that the fixing rods 5 are inserted into the fixing slots 6. Through the engagement of the fixing rods 5 and the fixing slots 6, the pull connection of a pair of reinforced sealing plates 3 is realized.

[0026] Then, according to the instruction manual attached Figures 1-3It can be seen that a pair of limiting ring edges 7 are symmetrically arranged on both sides of the pair of reinforcing sealing plates 3. The pair of limiting ring edges 7 are arranged along the outer edge of the pair of reinforcing sealing plates 3, and the pair of limiting ring edges 7 and the inner side of the frame of the pair of electrodes mutually limit each other.

[0027] As a preferred option, the outer edges of the pair of limiting rings are all sloped structures. The pair of limiting rings 7 are limited by the sloped structure and the pair of electrodes. The sloped structure facilitates the guidance and placement, so that the posture of the main body membrane 1 is aligned.

[0028] As a preferred option, furthermore, the several pairs of fixing rods 5 are several pairs of columnar structure plates, and the ends of the several pairs of fixing rods 5 are beveled structures, so that the fixing rods 5 can be inserted into the fixing slots 6.

[0029] As a preferred option, furthermore, the diameters of several fixed slots 6 and several pairs of fixed rods 5 are matched, a limiting block 8 is provided in the fixed slot 6 to match the fixed rod 5, and a limiting slot 9 is provided on the fixed rod 5 to match the limiting groove 4. The locking of the limiting block 8 and the limiting slot 9 makes the connection of a pair of reinforced sealing plates 3 tighter.

[0030] Example 2: In order to match the above-mentioned ion exchange membrane, this application also discloses an electrode frame 10. The electrode frame 10 is a rectangular ring plate. A limiting ring groove 11 is provided on the electrode frame 10 corresponding to the limiting ring edge 7. The limiting ring groove 11 matches the limiting ring edge 7.

[0031] In the specific implementation process, the electrodes are installed through the electrode frame 10. Two pairs of mounting holes should be provided at the four corners of the electrode frame 10. At the same time, the limiting ring groove 11 and the limiting ring edge 7 provided on the electrode frame 10 realize the limiting position, realize the limiting function of a pair of reinforcing sealing plates 3, and thus realize the positioning and fixing function of the main body membrane 1. A through groove is provided in the center of the electrode frame 10 for placing the electrode. The electrodes in a pair of electrode frames 10 correspond to the main body membrane 1.

[0032] In summary, the ion exchange membrane structure employs a fixing plate 2 integrated around the main membrane 1 as the integral structure of the ion exchange membrane. The fixing plate 2 is slightly thicker than the main membrane and forms a membrane frame through a pair of reinforcing sealing plates 3. The reinforcing sealing plates 3 are mutually limited by the fixing plate 2 through the limiting groove 4. The pair of reinforcing sealing plates 3 are fastened to each other to fix the main membrane. The installation of the ion exchange membrane is achieved by limiting the pair of reinforcing sealing plates 3 with a pair of electrode frames 10. The structure is simple and easy to handle and install.
