A PEEK cell for measuring the ionic conductivity of ion-exchange membranes and other solid membranes. The membrane is fixed between the electrodes by tightening the corner screws and its resistance is measured by impedance spectroscopy.
The two-electrode model uses platinum sheet electrodes. The four-electrode model has platinum wires and supports both two- and four-electrode methods; in the four-electrode method current flows through the outer electrodes and voltage is measured at the inner ones, reducing the effect of contact resistance.
