ZENNIUM X Potentiostat/Galvanostat/FRA

  • The ZENNIUM X is a modular electrochemical measurement device.
  • It is implemented in the electrochemical characterization of fuel cells and electrolyzers.
  • The instrument support DC techniques like Cyclic Voltammetry (CV) for ECSA determination or Linear Sweep Voltammetry (LSV) for Hydrogen crossover characterization.
  • A high-end FRA for Electrochemical Impedance Spectroscopy (EIS) is implemented in each ZENNIUM X.
  • 32 bit DC resolution and 24 bit AC resolution across 12 different current ranges enable it to carry out outstandingly precise and accurate measurements.

Product features:

  • DC voltage ranges: ±5 V and ±15 V
  • Current up to ±4 A over 12 current ranges
  • EIS frequency range from 10 µHz to 12 MHz
  • AC amplitude of 0 – 6 V or 0 – 4 A for EIS
  • Up to 17 parallel channels for EIS (4 PAD4 cards)
  • Switchable floating / grounded mode
  • ADF technology for fast CV (up to 10 kV/s)
  • TCP/IP protocol for test stand integration based on Python, LabVIEW or Cpp protocols

Application areas

  • The ZENNIUM X finds in application in test rigs form single cell or short stack investigations where it is often connected in parallel to third party load banks
  • Due to its modular concept the ZENNIUM X, the current range of the ZENNIUM X can be expanded for medium to large fuel cell or electrolyzer systems.
  • With PAD4 card plug-in cards the ZENNIUM X can be implemented in stack test stands where it can measure up to 17 cells at the same time.

    Zahner-Elektrik GmbH & Co. KG

    Since 1976, Zahner is manufacturing potentiostats for use in the field of electrochemistry. With a core competence in impedance spectroscopy, Zahner has designed its potentiostats with the modularity concept that can be customized to the needs of the customers. Zahner potentiostats can be easily extended for medium power (up to 200 W) and high power (up to 68 kW) applications. In addition, the potentiostats can also be equipped with addon cards which further increase their functionalities i.e., with PAD4 cards, Zahner potentiostats can simultaneously record multiple spectra from each segment of a fuel cell or electrolyzer.
