Observable CO2RR Gas Diffusion Flow Cell

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.

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.

How to choose the size of Reference Electrode?

How to choose the size of Reference Electrode? The diameter of ERA131B [ Silver Silver Chloride Ag/AgCl Reference Electrode Φ4*50mm Glass Rod ] glass tube is 4mm, which is not the best choice for CHR221B2. The diameter of ERA131A [ Silver Silver Chloride Ag/AgCl Reference Electrode Φ6*70mm Glass Rod ] is 6mm, which is more suitable for CHR221B2. L et me briefly introduce this electrochemical cell for you.I attached two images, so you can see it clearly: Figure 1 is the default opening diagram of CHR221B2 [ H-Type Sealed Electrochemical Cell 30ml 45ml ] . The left side is the working electrode chamber opening diagram, and the right side is the counter electrode chamber opening diagram. As shown in the parameter diagram on our product details page, we place the working electrode and the reference electrode in a chamber, and are equipped with gas inlet and outlet holes [for inert gas protection and oxygen-free o...

How to Choose the Reference Electrode?

According to the test requirements, you can use the following content as a reference for selecting reference electrode. Different research systems can choose different reference electrodes: Neutral system: saturated calomel electrode or Ag/AgCl reference electrode Alkaline system: Hg/HgO reference electrode Acidic system: Hg/Hg2SO4 reference electrode Non-aqueous system: Non aqueous Ag+ reference electrode Compared with other reference electrodes, Ag/AgCl reference electrode is more sensitive to light.At the same time, the silver chloride electrode is also less affected by temperature than other types of reference electrode. If you choose calomel electrode, Hg2/HgSO4 electrode or Hg/HgO electrode, you can add a salt bridge under the electrode to protect the reference electrode and minimize the potential affected by temperature. Mercury Oxide Reference Electrode Hg/HgO PTFE Rod 6 * 60 mm is a good choice for the Alkaline system. you can find all the reference electrodes from ...

What is the CO2RR Gas Diffusion Flow Cell?

The CO2RR Gas Diffusion Flow Cell (CO2RR GDFC) is a type of electrochemical cell used in the conversion of carbon dioxide (CO2) to other chemicals through a process called the CO2 reduction reaction (CO2RR). It is similar in design to the Gas Diffusion Flow Cell (GDFC) used to measure gas permeability, but it is specifically designed to facilitate the electrochemical reduction of CO2. The CO2RR GDFC consists of a small, sealed chamber with two compartments separated by a thin, gas-permeable membrane. One compartment is filled with a CO2-containing gas mixture, while the other compartment contains an electrolyte solution and a catalyst material, such as copper or silver, which facilitates the CO2RR. The two compartments are separated by the gas-permeable membrane, which allows CO2 to diffuse from the high concentration compartment to the low concentration compartment. The CO2RR is driven by an electric potential applied across the two compartments, which induces the reduction of CO2 int...
