MegaEIS™ ME-10S500x20

Kolibrik

The MegaEIS™ ME-10S500x20 is the ideal workstation with an internal power source from the Kolibrik MegaEIS Product Family, purpose-built 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. Delivering up to 500 A, the ME-10S500x20 makes even the most demanding electrolyzer experiments feel effortless.

Key Features

  • Designed for electrolyzer stack research
  • Stack current up to 500 A
  • Stack voltage up to 20 V
  • Inner dissipated power of MegaEIS up to 10 kW
  • EIS measurement one cell gradually or all cells simultaneously
  • High precision current sensing of both DC and AC components

Deployment Scenarios

  • Industrial Short Stack Validation: Test large-format cells under true operational conditions. With up to 500 A from the integrated power source, you can validate cell-to-cell uniformity across 10 channels simultaneously, ensuring balanced voltage distribution in components with industrial-scale active areas.

  • High-Current Density Stress Testing: Push your stack to its thermal and electrochemical limits. True parallel EIS captures real-time degradation data—such as mass transport limitations or localized hot spots—while continuously driving the stack at 500 A without requiring external boosters.

  • High-Power Dynamic Load Profiling: Simulate aggressive renewable energy fluctuations natively. Execute automated, high-current load cycling sequences to observe transient responses and optimize thermal management strategies for heavy-duty electrolyzer designs.
