Basic electrochemical H-cell setup (redox.me)

This is a stationary solution double compartment electrochemical H-Cell for measurements of electrodes in a form of:

a) rod/disc (6 mm dia.),

b) thin film deposited on a flat substrate (using a wire clip) and

c) membrane (using a wire clip).

 

The working, counter and reference electrodes are mounted in a top casing either in 2-, or 3-electrode setup. The counter electrode is placed in a compartment separated from the other electrodes by ion-exchange membrane (19 mm to 25 mm dia.), so the electrochemical products appearing at working and counter electrode do not affect the opposite electrode. The counter electrode compartment is equipped with a separate inlet and outlet for easy filling with an electrolyte and evacuation of gaseous products. It can accommodate standard Metal Wire Auxiliary Electrode as well as square shape electrodes with sizes up to 25 mm x 25 mm. The cell elements are constructed with materials that are inert to the sample (glass and PEEK). It well fits aqueous (FKM/EPDM O-Rings) and organic solvent (FFKM O-Rings) electrolyte requirements. The construction is gas-tight and can be used when the removal and exclusion of contaminants such as oxygen and water is required by bubbling of an inert gas through the electrolyte. After removal of the counter electrode glass compartment, the cell gets the functionality of a Basic Electrochemical Cell – BEC 50 mL. 

The cell chamber is available in several material variants here.

 

Application note:
The reference electrode tip and working disk electrode tip should be placed in the middle of the membrane. This will ensure a low potential drop throughout the electrolyte solution for low-current experiment. Various auxiliary electrodes are suitable for this cell including metal wire and metal foil/mesh/foam electrodes as well as graphite rod. The bubbling of gas through the solution must be stopped prior to experiment.

  • Membrane Capacitive Deionization configurable cell (redox.me)

    Membrane Capacitive Deionization (MCDI) configurable cell has been designed to conduct research on removal of charged ionic species from aqueous or organic solutions (i.e., Desalination/Demineralization) via electrostatic (i.e., non-Faradaic) or electrochemical (redox) interactions. The MCDI cell contains two graphite current collectors that can serve as polarization electrodes. However, if the electrode material is the subject of research, it should be applied to an additional current collector, such as graphite paper or metal felt (not included in the product). Different electrode materials can be installed on both sides of the cell. If the thickness of these electrodes exceeds 250 micrometers, different gaskets are required. In such a case, please contact us for a solution.

    The cell is designed in such a way that replacing the electrodes does not require removing the membranes or flow fields. It is enough to unscrew the plungers on both sides and replace the electrodes. In the standard configuration, the liquid in the main channel and side channels flows through the flow field cut from PEEK. However, these can be replaced with a porous material such as felt or a battery spacer, which will allow fluid flow. If work with materials of dimensions different from those listed in the specification is required, we can supply seals of different thicknesses or customize the cell. The cell allows for the installation of one or two ion-exchange membranes (not included in the setup). Their thickness is not critical, and it is not necessary to adjust the thickness of the membrane gaskets pressing them. The cell elements are constructed with inert materials to the sample (PEEK). It well fits aqueous (FKM gaskets and O-rings) and organic solvent (FFKM gaskets and O-rings) electrolyte requirements. The construction of the cell is gas-tight.

     

    Application note:
    MCDI cell can be configured to allow the following cell architectures:

    1. Flow-by CDI consisting of: (i) two porous carbon or metal based current collectors coated with capacitive (e. non-Faradaic) material, and (ii) a main flow field enabling the feed water to be transported between electrodes. In this configuration, side flow fields and membranes are not installed.  
    2. Membrane CDI consisting of: (i) two porous carbon or metal based current collectors coated with capacitive (e. non-Faradaic) material, (ii) two ion-exchange membranes (cation exchange membrane and anion exchange membrane) separating electrodes from the main flow field, and (iii) a main flow field enabling the feed water to be transported between electrodes. In this configuration, side flow fields are typically not installed. However, there are cases where installing both side flow fields is justified. All the graphics included in the product page refer to that configuration.
    3. Inverted CDI consisting of: (i) two porous carbon or metal based current collectors coated with capacitive (e. non-Faradaic) material where anode is treated for net negative surface charge and a cathode is treated for net positive surface charge, and (ii) a main flow field enabling the feed water to be transported between electrodes. In this configuration, side flow fields and membranes are not installed.  
    4. Flow-electrode CDI consisting of: (i) two porous carbon or metal based current collectors with flowing electrodes made of capacitive (e. non-Faradaic) carbon suspension, (ii) two ion-exchange membranes (cation exchange membrane and anion exchange membrane) separating electrodes from the flow chamber, (iii) a main flow field enabling the feed water to be transported between electrodes, and (iv) two side flow fields for liquid electrodes. All the graphics included in the product page refer to that configuration.
    5. Hybrid CDI consisting of: (i) a Faradaic (e. battery) electrode for cation adsorption/desorption, (ii) a capacitive (i.e. non-Faradaic) electrode for anion adsorption/desorption, (iii) an anion exchange membrane placed adjacent to the capacitive electrode, and (iv) a main flow field enabling the feed water to be transported between electrodes. In this configuration, side flow fields and a cation-exchange membrane are not installed.  
    6. Cation intercalation desalination consisting of: (i) two porous carbon or metal based current collectors coated with Faradaic cation intercalation materials, (ii) an anion exchange membrane separating electrodes, and (iii) a main flow field enabling the feed water to be transported between electrodes. In this configuration, one side flow field and cation-exchange membrane are not installed.  
    7. Desalination battery consisting of: (i) two porous carbon or metal based current collectors coated with redox (e. Faradaic) material (one for cation adsorption/desorption and the other for anion adsorption/desorption), and (ii) a main flow field enabling the feed water to be transported between electrodes. In this configuration, side flow fields and membranes are not installed.
