Description

For the past two decades, Electrochemical Impedance Spectroscopy (EIS) has emerged as the most powerful of electrochemical techniques for defining reaction mechanisms, for investigating corrosion processes, and for the characterization of batteries and fuel cells.

Z# series provides all tools for the application of fuel cell stack, battery pack , multi cells and general electrochemical study requiring multichannel EIS for serial connected cells.

By employing electronic load, Z# can be used to determine the efficiency of fuel cell and anodic/cathodic process mechanisms by calculating impedance with the measurements of I and E at given frequency.

The complete system is software-controlled and all functions such as ranging, calibration, and measurements can be automated.

30 cell EIS measurement configuration (example)

For 30 cells eis measurement, 6 set of Z#106 is needed. Then you can measure eis of 30 cells or 29 cells with one total fuel cell stack(or battery pack).;

One Z#106 will work as master and other 5 set of Z#106 works as slaves.
