MegaEIS™ ME-10S270x20
Kolibrik
The MegaEIS™ ME-10S270x20 is the essential workstation with internal power source from the Kolibrik MegaEIS Product Family, specially designed for electrolyzer stack research.
With 10 fully synchronized measuring channels, it’s ideal for parallel testing of small to mid-size stacks — capturing real-time insights into cell uniformity, degradation mechanisms, and efficiency under industrial-scale loads. Offering up to 270 A, the ME-10S270x20 provides all the necessary power and stability to execute a broad spectrum of electrolyzer experiments with ease.
Key Features
- Designed for electrolyzer stack research
- Stack current up to 270 A
- Stack voltage up to 20 V
- Inner dissipated power of MegaEIS up to 5.4 kW
- EIS measurement one cell gradually or all cells simultaneously
- High precision current sensing of both DC and AC components
Deployment Scenarios
-
Short Stack Scale-Up Validation: Bridge the gap between single-cell R&D and large-scale production. Monitor cell-to-cell uniformity across up to 10 cells simultaneously, instantly identifying voltage imbalances or weak components within the electrolyzer short stack.
-
Accelerated Degradation Testing: Drive the stack with up to 270 A using the integrated power source. True parallel EIS captures real-time data on specific degradation mechanisms—such as membrane aging or catalyst poisoning—under continuous, high-current stress.
-
Dynamic Load & Efficiency Profiling: Simulate fluctuating renewable energy inputs natively. Run custom, automated sequences of load cycling and polarization curves to observe transient responses and optimize overall stack efficiency without requiring external power hardware.
