The MegaEIS™ ME-130L2000x200 is our highest-capacity multi-channel load and EIS workstation, engineered specifically for full-scale, megawatt-class hydrogen fuel cell stacks.

Featuring 130 fully synchronized measuring channels, it delivers true parallel EIS data across massive assemblies without multiplexing delays.

Capable of sinking up to 2000 A natively and supporting external boosters up to 400 kW, the system provides the extreme, stable loading required to validate heavy-duty automotive, marine, and aviation fuel cells under the most aggressive real-world operating conditions.

Use cases

Megawatt-Scale Stack Validation: Transition safely to full industrial or heavy-transport applications. Monitor cell-to-cell uniformity across 130 channels simultaneously, instantly identifying voltage drops or weak components within massive stack assemblies operating at 2000 A.

Heavy-Duty & Marine Drive Cycle Simulation: Replicate extreme, high-current load profiles native to heavy-duty transport, rail, or marine applications. Sink up to 2000 A natively to evaluate transient stack responses, massive thermal management demands, and fuel starvation risks during rapid power fluctuations.

Extreme-Current Water Management Diagnostics: Track specific impedance shifts under extreme, continuous loads. True parallel data acquisition pinpoints localized membrane drying or cathode flooding across the entire 130-cell stack in real time, preventing catastrophic failures and irreversible cell reversal during peak power operation.
