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
