ElyFlow - Electrochemical Test Cell
ElyFlow is a test cell optimized for electrolyte circuits for electrochemistry with a three-electrode set-up.
ElyFlow - Test Cell with Three-electrode Set-up
ElyFlow is a test cell optimized for electrolyte circuits for electrochemistry with a three-electrode set-up. Working electrode and counter electrode are arranged in parallel. The reference electrode, preferably a Mini-HydroFlex, is located in a separate reservoir. The potential is measured via Haber-Luggin capillaries that end directly at a fixed distance from the working electrode. In addition, the electrolyte can be pumped through the cell.
The newly developed measuring cell from Gaskatel offers completely new possibilities for your electrochemical measurements.
It is optimized for measurements with an electrolyte circuit.
You can use it to characterize your plates and gas diffusion electrodes as usual.
Investigations on membranes are also possible with it.
Is hydrogen permeation your topic? No problem – this can also be investigated with ElyFlow.
Like FlexCell, ElyFlow is also flexible with regard to the sample (e.g. metal sheet, foils, gas diffusion electrode) – but rigid where it really counts:
- Fixed and thus defined distance between the working and the counter electrode
- Fixed and thus defined distance between the working and the reference electrode
ElyFlow chemical resistant and indestructible since it is made of polytetrafluorethylene (PTFE).
With the Nickel counter electrode, ElyFlow can be used in a pH range of pH 10 to pH 16. For measurements in a pH range pH -2 to 10, use the MMO counter electrode.
The electrolyte volume is only 25 ml.
Applications of ElyFlow
Electroplating
With an electrolyte circuit, controlled electroplating is possible because the electrolyte is constantly renewed. Thus, a depletion of the reactants in front of the working electrode is excluded.
CO2 Reduction
The electrochemical conversion of CO2 into formates or carbonates is highly topical. ElyFlow enables the electrolyte to be continuously renewed. In the storage vessel, for example, temperature, pH value, or conductivity can be monitored. In addition, an analysis of the reaction products can be carried out with the appropriate sensor technology.
Determination of Membrane Resistance
Since each analyte compartment has Haber-Luggin capillaries, you can use two analyte compartments to measure the membrane resistance. To measure the voltage drop across the membrane, both analyte compartments must be positioned so that the Haber-Luggin capillaries face the membrane. The voltage drop across the membrane is taken as the difference between the two reference electrodes inside the Haber-Luggin capillaries.
Hydrogen Permeation
Hydrogen uptake and permeation during electrochemical processes is a critical effect on the mechanical stability of some metals, especially iron- and copper-based materials. With our test cell ElyFlow and the Gaskatel Control Box, we are launching a complete and robust measuring system for the determination of hydrogen permeation, which performs its electrochemical measuring service without the use of expensive potentiostats.

What are Electrochemical Cells?
Electrochemical cells are systems that convert energy of chemical reactions into electrical energy. Conversely, electrical energy can also be used for electrochemical reactions.

The Importance of Field Lines
The potentials which are to be measured are only identical on the so-called equipotential surfaces.
Homogeneous electric field lines are required for correct measurements. Here you can learn more about parallel field lines, equipotential surfaces and IR-drop.
The Importance of Haber-Luggin Capillaries
The electrolytical contact between the working and the reference electrode is made by the Haber-Luggin capillary. Haber-Luggin capillaries are reducing the IR-Drop between reference electrode and working electrode.
Electrolyte Key – Salt Bridge
An electrolyte bridge, also known as a salt bridge, is used for the contacting of various electrolytes. Commercial reference electrodes rely on salt bridges.
