Electrochemical impedance spectroscopy (EIS) for online monitoring of electrolyzers

Electrochemical impedance spectroscopy (EIS) helps to monitor and improve electrolysers. It measures the electrical resistance at various frequencies and provides valuable information on the condition of the cells. This allows problems to be identified at an early stage and efficiency to be increased.

Multi-channel technology for large systems
Modern EIS systems can analyze several cells simultaneously. This is particularly useful for large systems. The technology provides data on electrochemical processes, chemical reactions and mechanical properties. This information helps to optimize operation and increase performance in the long term.

Better predictions with artificial intelligence
A major advance is the combination of EIS with machine learning. Artificial intelligence can evaluate large amounts of data and detect deviations at an early stage. This allows maintenance to be planned in a targeted manner and failures to be avoided.

EIS data helps to precisely analyze the condition of the cells. This makes it possible to clearly distinguish between normal and abnormal behavior and improve processes.

Precise measurements with SIVONIC
The multi-channel EIS meter from SIVONIC was specially developed for this application. It offers high accuracy, processes data in real time and can be easily integrated into existing systems.

More efficiency and safety
EIS brings many advantages for electrolysers:

  • Real-time monitoring
  • Increased safety during operation
  • Early detection of faults
  • More efficient maintenance
  • These factors extend the service life of the systems and reduce costs. At the same time, the optimization of operating parameters improves hydrogen production.

The SIVONIC EIS meter makes electrolysers more efficient, reliable and sustainable. It contributes to the production of green hydrogen and a climate-friendly energy future.
