Electrocatalytic reduction of CO2 can store renewable energy in the form of chemical raw materials and high-value chemicals, which is one of the important methods to solve energy problems. Most researches on CO2 electroreduction use H-type electrolytic cell, but the mass transfer in H-type electrolytic cell severely limits the reaction rate, that is, the current density. The flow electrolytic cell not only breaks through the mass transfer limitation of the H-type cell, and enables the CO2 reduction current density to reach the industrial level. At the same time, it can also use a high pH electrolyte to inhibit the hydrogen evolution reaction.

Our Recommendations

Product Details

In the ongoing development of electrocatalytic carbon dioxide reduction (CO2RR) technology, researchers have discovered that by using a gas diffusion electrode (GDE) with a flowing catholyte, it is possible to evaluate the electrocatalytic performance of these catalysts regardless of mass transfer limitations and local pH effects. That is, a so-called flow electrolytic cell is constructed to replace the static H-type electrolytic cell in the traditional sense.

In the flow electrolysis cell, CO2 enters the cathode of the electrolysis cell from the back of the gas diffusion layer, and reacts with H+ from the electrolyte in the cathode catalytic layer to be reduced, and the reduction product is discharged from the electrolysis cell through the gas diffusion layer.

The flow electrolysis cell can not only alleviate the mass transfer polarization caused by the low solubility of CO2 in water, but also suppress the hydrogen evolution side reaction due to the use of a flowing electrolyte, and reduce the CO2 activation energy barrier and enhance the CC coupling between *CO, thereby increasing the selectivity of the C2 product.Continuous reaction can bring the advantage of no backflow of materials, so that the product can not be over oxidated and reduced, and the product yield can be improved.


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.


1.The main body of the flow cell is made of PEEK 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 is used for air inlet and outlet, and its outer size is 60*60*19mm. The flow channel adopts the S-shaped flow channel, which can make the CO2 flow in along the S-shaped direction next to the GDE, and then output from the end of the flow channel to the online chromatographic detection and analysis. We use a unique design. Place a φ20*2.4mm fluorine rubber ring on the outside of the S-shaped runner, the fluorine rubber ring protrudes by 0.3mm, and the GDE material is placed on it. When the entire device is assembled, tighten the four fixing rods to achieve the GDE and S-shaped runners close to each other and achieve a sealing effect.

4.Chamber B is used as a catholyte cell, and its outer size is 60*60*10mm. The catholyte is circulated through a peristaltic pump. A φ4mm reference electrode is placed on the top of the chamber. When the electrolyte is an alkaline solution, the user can choose to buy a reduced diameter salt bridge φ6mm to φ4mm, and use it with DekResearch's φ6mm mercury oxide reference electrode.

5.Chamber C is used as an anolyte cell, and its outer size is 60*60*10mm. Considering that the anode material produces more oxygen, when the anolyte is also circulated through the peristaltic pump, the holes 5 and 6 are used as the anolyte inlet and outlet. At this time, use a solid sealing screw to block the hole 7. Alternatively, the hole 7 can be used as a circulation outlet hole, and the hole 6 can be blocked with a sealing screw. When the anolyte is not circulating, use solid sealing screws to block both holes 5 and 6, and open hole 7 for exhaust.

6.Chamber D is used as a fixed plate, and the outer size is 60*60*19mm.

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.

1. This is a customized item, we can't offer any refund or exchange. If you have any questions before purchasing, please feel free to communicate with us.
2. There are two types of materials for Chamber A: PMMA and PEEK. The advantage of PMMA is that the flow channel can be observed, but the disadvantage is that its strength is not as high as PEEK. If the user chooses PMMA material, special attention should be paid to the installation process, and the force of the fixing rod should not be too large. Meanwhile, the four rods should be tightened with the same torque.
3. The installation of the new accessories PTFE flat pads and Kapton tape is demonstrated below.

How to choose ordinary electrochemical cell and sealed electrochemical cell?
Regardless of the user's tightness requirements for the actual test, the sealed electrochemical cell is the first choice. The sealed electrolytic cell is equipped with hollow sealing screws and fluorine rubber O-rings to install and seal the entire device, and then pass inert gas into the cell body to drive out the excess gas inside the cell body to realize the test of the system in an inert environment. If there is no requirement for tightness, no ventilation operation is required. However, if you choose an ordinary electrochemical cell, the related operations of the sealed electrolytic cell cannot be realized.
What volume of electrochemical cell is suitable to choose?
The volume of the electrolytic cell should be selected moderately. If the volume is too large, the amount of solution will be too much, which is unnecessary. During electrochemical measurement, the electrode surface undergoes oxidation and reduction reactions, and some substances in the solution are reduced by participating in the electrode reaction. At the same time, some reaction products will dissolve into the solution. If the volume of the electrolytic cell is too small, the solution concentration will change significantly during the long-term steady-state measurement, which will eventually affect the experimental results. In most cases, the volume of 50ml and 100ml are more choices.
How to choose a working electrode?
Common working electrodes include disk electrodes and replaceable electrode holders. The disk electrode is suitable as the base of the modified material, and it is modified to the base area of the disk electrode by mixing a membrane solution or the like with a powdered material. And if the material being studied is a sheet-like structure or the material can be modified to suitable materials such as conductive glass, carbon paper, carbon cloth, etc., it is more practical to choose a replaceable electrode clip.
How to choose a counter electrode?
One of the important parameters of the counter electrode is its surface area. The counter electrode must have a large enough area to support the current conduction generated on the working electrode. Generally, the area of the counter electrode is 3-5 times the area of the working electrode. When choosing a disk electrode as the working electrode, platinum wire electrode is a good choice. When choosing sheet materials as working electrodes, platinum wire ring electrodes and platinum sheet electrodes are good choices.
How to choose a reference electrode?
Generally speaking, calomel electrode or Ag/AgCl reference electrode is used in neutral system. Since the potential of calomel electrode changes greatly with temperature, when the temperature exceeds 70 degrees, it needs to be used with a salt bridge or replaced Use Ag/AgCl reference electrode. Hg2SO4 reference electrodes are generally suitable for sulfuric acid or sulfate systems. Hg/HgO reference electrodes are generally suitable for alkaline electrolyte solutions, of which the strong alkali system also needs to be used with a salt bridge, and the filling liquid in the salt bridge is consistent with the filling liquid of the reference electrode. The non-aqueous organic system needs to use a Ag/Ag+ reference electrode. When using a non-aqueous Ag/Ag+ reference electrode, the user needs to prepare a solution containing supporting electrolyte and silver ions (usually 10mM) and inject it into the reference electrode chamber. Due to shipping safety considerations, all reference electrodes are not filled with solution. Before use, the user needs to prepare an internal solution to fill it into the electrode.
