Stack EIS Analyzer

Impedance spectroscopy measurement at high-power fuel-cell stacks

  • EIS measurement on stack voltage or particular cells
  • Works as AC load in parallel with a standard high-power DC load
  • High precision current sensing of both DC and AC components
  • For stacks operated at DC current up to 1000 A and more than 100 V
  • In development, prototype of 100V and EIS AC 10A will be available in spring of 2019
