Detailed Implementation

[0020] 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.

[0021] Example: Figures 1-4 As shown, a multifunctional stacked electrolytic cell for solid electrolytes includes a gas chamber 1 and an anode chamber 2. Both the gas chamber 1 and the anode chamber 2 have two connection ports 12, which are staggered, one above the other. Both the gas chamber 1 and the anode chamber 2 have four through-holes 13, evenly distributed. Nuts 11 are installed inside each of the four through-holes 13 on the gas chamber 1. Long bolts 9 pass through the through-holes 13 on both the gas chamber 1 and the anode chamber 2, and the long bolts 9 are threaded into the nuts 11. Each connection port 12 on both the gas chamber 1 and the anode chamber 2 is equipped with a quick-connect fitting 14 for connecting the flanges of the connecting pipes. Through this design, the through-holes 13 on the gas chamber 1 and the anode chamber 2 form a through-hole, and the long bolts 9 are connected to the nuts 11 through the through-hole, facilitating the connection between the gas chamber 1 and the anode chamber 2. The two quick-connect fittings 14 connected to the gas chamber 1 are the gas inlet and the gas outlet, respectively, and the two quick-connect fittings 14 connected to the anode chamber 2 are the liquid inlet and the liquid outlet, respectively.

[0022] Both the gas chamber 1 and the anode chamber 2 have channels 6 on their inner surfaces. The channels 6 can be any of the following: serpentine, mesh, or hollow. In this embodiment, the channel 6 is serpentine to facilitate the flow of electrolyte and the filling of solid electrolyte.

[0023] A cathode cavity 3 is provided between the gas cavity 1 and the anode cavity 2. Threaded openings are provided at opposite corners of the cathode cavity 3. A through hole 5 is provided at the center of the cathode cavity 3. Through grooves are provided in the threaded openings at opposite corners of the cathode cavity 3, and the through grooves are connected to the through holes 5. With the above scheme, the threaded openings at opposite corners of the cathode cavity 3 facilitate the installation of the reference electrode flange adapter 4 and the flange quick connector 10, and the through grooves facilitate the input and output of electrolyte.

[0024] Gas chamber 1 and cathode chamber 3 are connected by short bolt posts 7. Gaskets are provided on both sides of cathode chamber 3. The gasket between cathode chamber 3 and gas chamber 1 is an anion exchange membrane, and the gasket between cathode chamber 3 and anode chamber 2 is a cation exchange membrane. The short bolt posts 7 are used in conjunction with screw holes 8. Through the above scheme, firstly, the connection between gas chamber 1 and cathode chamber 3 is convenient for filling solid electrolyte, and secondly, the solid electrolyte will not shake during the installation of anode chamber 2, thus ensuring the stability of the electrolytic cell structure.

[0025] The reference electrode flange adapter 4 and the flange quick connector 10 are respectively connected to the threaded openings on opposite corners of the cathode cavity 3. The reference electrode flange adapter 4 is set at 45° with the cathode cavity 3. A reference electrode is connected to the reference electrode flange adapter 4. With the above scheme, the reference electrode flange adapter 4 is connected to the threaded opening on the cathode cavity 3. The reference electrode flange adapter 4 is also provided with a quick connector for connecting the electrolyte tube for electrolyte input. The flange quick connector 10 is connected to the threaded opening on the cathode cavity 3. An electrolyte tube is connected to the flange quick connector 10 for electrolyte output.

[0026] The gas chamber 1 and anode chamber 2 are made of high-purity titanium, while the cathode chamber 3 is made of plastic. By using plastic for the cathode chamber 3, the voltage between the gas chamber 1 and anode chamber 2 is prevented from being too high, which would affect the experimental results of the electrolytic cell. High-purity titanium has high strength, high thermal strength, good corrosion resistance, good low-temperature performance, and high chemical activity, thus effectively extending the overall service life of the electrolytic cell.

[0027] The cathode cavity 3 is I-shaped with a thickness of 1.2 mm in the middle. The total thickness of the cathode cavity 3 and the gaskets on both sides of the cathode cavity 3 does not exceed 1.5 mm. With the above scheme, the thickness of the cathode cavity 3 and the two gaskets does not exceed 1.5 mm, which can effectively increase the overall current of the device and further improve the efficiency of the electrolytic cell.

[0028] In daily use, the gasket is first installed on the gas chamber 1. Then, the cathode chamber 3 is installed on the gas chamber 1 using multiple short bolts 7. The short bolts 7 are threaded into the screw holes 8. The solid electrolyte is filled into the through hole 5. The gas chamber 1 and the cathode chamber 3 are fixed in advance using the short bolts 7, making the electrolytic cell structure more stable and ensuring that the solid electrolyte will not shake or shift during the installation of the anode chamber 2. Then, the gas chamber 1, anode chamber 2, and cathode chamber 3 are fixedly connected using long bolts 9, further improving the stability of the electrolytic cell. Finally, the connection ports 12 on the gas chamber 1 and anode chamber 2 are fitted with flanged quick connectors 14 to allow gas to pass through. Moist CO2 gas is introduced through one quick-connect fitting 2 14 on the gas chamber 1, and CO2 gas is output from the other quick-connect fitting 2 14 on the gas chamber 1. Acidic electrolyte is introduced through one quick-connect fitting 2 14 on the anode chamber 2, and acidic electrolyte is output from the other quick-connect fitting 2 14 on the anode chamber 2. The reference electrode quick-connect fitting 4 and quick-connect fitting 10 are installed diagonally on the cathode chamber 3, respectively. The electrolyte tube is installed on the quick-connect fitting on the reference electrode quick-connect fitting 4 and quick-connect fitting 10. Electrolyte is input through the quick-connect fitting on the reference electrode quick-connect fitting 4 and output through quick-connect fitting 10. Further, from... Figure 5 , Figure 6As can be seen, the multifunctional stacked electrolytic cell with solid electrolyte can operate for up to 200 hours when the voltage is stable, and the multifunctional stacked electrolytic cell operates stably during long-term operation.
