Characteristic:

1. Compared with the usual H-type electrolytic cell, the liquid flow electrolytic cell has more advantages in liquid phase mass transfer kinetics.

2. Directly supply CO2 gas to the cathode, which overcomes the disadvantages of low solubility and slow diffusion of CO2 gas in aqueous solution.

3.The thickness of the electrode plate can be customized according to the needs, which can effectively shorten the distance between the anode and the anode, reduce the resistance, and improve the test efficiency.

Parameter:

1.The main body of the flow cell is made of PEEK and PMMA material, which is made by meticulous crafting.

2.The designed working area of ​​the flow cell is 1cm2, which is square 10*10mm. Other areas can also be customized according to user requirements.

3.Chamber A, with an outer size of 60*60*15mm, functions as the air inlet and outlet. The flow channel is designed in an S-shape, which allows CO2 to flow in along the S-shaped direction next to the GDE, and then output from the end of the flow channel for online chromatographic detection and analysis. To achieve a sealed effect, a unique design places a φ20*2.4mm fluorine rubber ring on the outside of the S-shaped runner, with the fluorine rubber ring protruding by 0.3mm, and the GDE material placed on it. When the entire device is assembled, tightening the four fixing rods brings the GDE and S-shaped runners close together. Chamber A is constructed using PMMA organic glass and after polishing, the gas flow channel can be directly observed, which is beneficial for observing whether the catholyte enters the flow channel through the GDE.

4.Chamber B functions as the catholyte cell, with an outer size of 60*60*10mm. The catholyte is circulated through a peristaltic pump, and a φ4mm reference electrode is positioned on the top of the chamber. If the electrolyte is an alkaline solution, a reduced diameter salt bridge φ6mm to φ4mm can be purchased and used together with DekResearch's φ6mm mercury oxide reference electrode.

5.Chamber C serves as the anolyte cell, with an outer size of 60*60*10mm. To accommodate the production of more oxygen from the anode material, holes 5 and 6 are used as the anolyte inlet and outlet, respectively, when the anolyte is circulated through the peristaltic pump. In this case, a solid sealing screw is used to block hole 7. Alternatively, hole 7 can be used as a circulation outlet hole, and hole 6 can be blocked with a sealing screw. When the anolyte is not circulating, solid sealing screws are used to block both holes 5 and 6, and hole 7 is opened for exhaust.

6. Chamber D is used as a fixed plate, and the outer size is 60*60*15mm.

7. When the anode uses foamed nickel material, the anode can be clamped between the chambers C and D. It can also be clamped between the ion membrane and the chamber C, which can further shorten the distance between the cathode and the anode and reduce the internal resistance.

8.The conductive current collector equipped with this device is a copper foil with adhesive backing. Its thickness is 65um, which not only has good conductivity, but the thickness does not affect the sealing of the entire device. Users can also replace the appropriate conductive current collector according to their needs.

9.There are two types of gaskets: silicone gasket and fluorine rubber gasket, and the thickness is 1mm. It should be noted that when foamed nickel is used for the anode, considering the structure of the foamed nickel material, we designed a gasket with the same thickness as the foamed nickel, and the foamed nickel material is built into the gasket. When the entire device is tightened At this time, the anode foam nickel can be sealed from the thickness to prevent leakage. Therefore, we recommend that the anode choose a foamed nickel material with a thickness of 1mm.

10.The flow cell can be quickly assembled and disassembled, and it is easy to clean.
