Proton Exchange Membrane Conductivity Testing Device E501P
It is primarily used for measuring the bulk ionic conductivity (perpendicular to the membrane plane) of solid electrolyte membranes such as proton exchange membranes and ion-exchange membranes, and can also be employed for rapid measurement of the bulk resistivity or conductivity of conventional insulating or conductive thin films. The fixture is made mainly of stainless steel and PEEK, offering resistance to acids, alkalis, and high temperatures. Its electrode leads are positioned on the upper side of the fixture, enabling in-situ testing in electrolyte solutions (with the fixture placed inside a beaker) or under high‑temperature, high‑humidity conditions. During the clamping process, the metal electrodes move only vertically without rotating, thereby preventing damage to the membrane. Operation is straightforward: after cutting the membrane to size, place it into the fixture, tighten the knob to ensure proper contact—alternatively, a torque wrench can be used for precise pressure control—and then measure the membrane’s conductivity using the AC impedance spectroscopy (EIS) method.

How to judge the electrolytic cell yin and yang pole?
First of all, look at whether [anode] is an inert electrode (it will be clearly stated in the question) if it is not an inert electrode, such as copper, then copper takes part in the reaction: Cu-2e = = = Cu2 if it is an inert electrode, then only the ion anode in the solution needs to be considered as anion and the cathode as cation anode

The reference electrode is the electrode used as a reference for comparison when measuring various electrode potentials. The electrode to be measured and the reference electrode of the accurately known electrode potential value constitute a battery, and the electromotive force value of the battery can be measured to calculate the electrode potential of the measured electrode. The electrode reaction carried out on the reference electrode must be a single reversible reaction with stable electrode potential and good reproducibility. Usually, the slightly soluble salt electrode is used as the reference electrode, and the hydrogen electrode is only an ideal but not easy to realize reference electrode.

Basic requirements for reference electrode
The reversibility of the electrode is better and it is not easy to be polarized. This requires that the reference electrode is reversible and the exchange current density is large (10-5A/cm2). When the current flowing through the electrode is less than 10 − 7A/cm2, the electrode is not polarized. Even if a slightly larger current flows for a short time, the potential can quickly return to the original value after the power is turned off.
