About the product

Open Circuited Voltage (OCV) cell with possibility of measurement of potentials with reference to internal reference electrolyte e.g. V3+/V4+ or Zobell solution (50/50 Ferro/Ferricyanide solution).

This is a multi-functional cell intended as an add-on to an flow battery test setup with two fundamental assembly/application principles.

OCV cell with fittings for 1/8” OD tubing – for other diameters please make an inquiry
Electrolyte only gets in contact with graphite materials and corrosion resistant tubing/fittings
Gaskets/Spacers: PTFE, EPDM or VITON

Assembly Manual

Below the two working principles of the cell are described

Standard OCV cell : In this assembly the cell can be used for measurement of the OCV and individual cathode and anode overpotentials. I.e. this is is an invaluable tool for flow battery research and optimisation. Drawing below explains the working principles.

Left picture below (click for larger view) show the cell voltage, OCV and the cathode/anode over potential during charging/discharging of the vanadium flow battery cell. Right picture shows the same measurements during measurement of polarisation curve. In this picture also the difference between the cell voltage and the sum of the OCV and overpotential has been included and shows that within experimental precision (1-2 mV) of the equipment used the sum of these voltages equals the cell voltage.

OCV cell with internal reference potential : In this configuration the cell has the same capabilities as the standard OCV cell with the only difference that an additional half cell in the setup allows measurement of all potentials relative to a reference potential. Drawing below explains the working principles.
