MegaEIS™ System
For Fuel Cell Stacks, Electrolyzers, and Batteries
Up to 1000 Cells, Current up to 2 kA
The High-Power System for Electrochemical Research & Development
MegaEIS™ System is a precise modular testing device for EIS analysis of fuel-cell stacks, electrolyzers and batteries. The System consists of a power stage which handles the power, and EIS acquisition system which can perform impedance spectroscopy analysis at all cells simultaneously.
Get a true, uncompromised snapshot of your device's health. The MegaEIS™ System delivers a complete EIS profile by performing true parallel analysis on every cell of your stack or electrolyzer simultaneously. Thanks to a dedicated channel architecture without multiplexing, it captures a perfect, real-time picture of electrochemical performance. This combination of a robust, water-cooled power stage and high-fidelity acquisition makes it the definitive tool for demanding R&D, QA, and diagnostics.
World-Class Power, Globally Trusted. Precision is our baseline. That’s why our official partner and global leader, Gamry Instruments, chooses to offer Kolibrik MegaEIS™ System. This synergy of high-current hardware and world-class expertise delivers the most reliable measurement systems to researchers and gigafactories everywhere, fully ready for seamless 3rd-party integration.

- Flawless 3rd-party parallelization: Connect existing cyclers or power supplies using an external current probe to achieve exact, artifact-free EIS results, even during active charging and discharging.
Advanced Electrochemical Methods
True parallel EIS and continuous DC cell monitoring make the MegaEIS an exact, high-speed tool for R&D analysis and manufacturing quality control. Beyond impedance spectroscopy, the system natively executes a broad suite of methods:
- Standard Techniques: Execute polarization curves, chronopotentiometry, chronoamperometry, current interruption, and complex load cycling.
- Automated Method Sequencing: Seamlessly link multiple standard methods into custom, multi-stage experimental procedures without manual intervention.
- Advanced Scripting & Integration: Take full control of your test protocols via Pascal or Python scripting, including TCP/IP server support for integration with external supervisory systems.
Deployment Scenarios Across the Industry
Industrial Electrolyzer Scale-Up
Safely transition from single-cell research to commercial green hydrogen production. Drive full-scale systems natively or seamlessly parallelize with external boosters for extreme loads up to 1000 V and 2000 A. Utilize true parallel EIS to isolate specific degradation mechanisms under continuous operation.
Heavy-Duty Fuel Cell Validation
Simulate aggressive automotive, rail, and marine drive cycles. Sink massive currents natively—even down to true zero volts for short-circuit testing—to evaluate transient responses and localized cathode flooding across hundreds of cells simultaneously.
Dynamic Battery & rSOC Cycling
Execute seamless charge and discharge profiles using our architecture or by parallelizing with 3rd-party cyclers. Utilizing an external current probe, capture artifact-free State-of-Health (SoH) and dynamic EIS data during active operation without breaking the circuit or switching hardware.
Automated End-of-Line (EoL) Diagnostics
Eliminate manufacturing bottlenecks. Leverage simultaneous multi-channel data acquisition and programmable method sequencing to rapidly execute strict pass/fail diagnostics on industrial stacks, bypassing the time delays of traditional multiplexed systems.
