Application areas

  • Fuel cell research and development
  • Mid-size fuel cell stack validation

Use cases

  • Water Management & Flooding Diagnostics: Monitor specific impedance shifts in real time. True parallel EIS across 42 channels simultaneously pinpoints localized membrane drying or cathode flooding before they trigger irreversible cell reversal.
  • Dynamic Drive Cycle Simulation: Replicate heavy-duty automotive load profiles natively. Sink up to 200 A to evaluate transient stack responses and individual cell voltage stability during rapid power demand fluctuations.
  • Accelerated Degradation Testing: Isolate weak cells within mid-size stacks. Continuous parallel data acquisition allows for precise tracking of catalyst degradation and fuel starvation effects over extended high-current operational cycles without missing fast transient events.
