Conductivity Cells
In hydrogen research, a conductivity measurement cell is a specialized laboratory environment that is primarily used to precisely determine the electrical or ionic resistance of materials.

The CurrentVIEW user interface is easy to use and self-explanatory.It enables:single and continuous measurementsvisualisation in 2D, 3D and as valuessaving data as text files in spreadsheet formatsaving data as pictures in jpg and bmp formatsaving and reviewing data streams.The image shows the main window of the user interface. From here, the options are available and the device can be calibrated. Single and continuous measurements can be started and the data can be displayed as numbers, as 2D graphics or 3D graphics. In addition, the data can be saved in a file in spreadsheet format. The format can be read by other programmes for further analysis.
In a fuel cell, it is used for the following purposes:
- The most important area of application is the measurement of the proton conductivity of the polymer electrolyte membrane (PEM).
- In-plane measurement: Conductivity is measured along the membrane surface. This is technically simpler and often serves as a standard test for new materials.
- Through-plane measurement: Here, the resistance is measured through the membrane (across the surface). This value is crucial for later use in the fuel cell, as the protons take this path.
It is a prerequisite for:
- Minimizing resistance losses.
- Finding the optimum humidity and temperature for maximum ion conduction.
- Detecting the aging process (degradation) of components at an early stage through changes in conductance values.
