Cell Voltage Monitoring
Delivering Fast & Reliable Data
for Cell Safety and Peak Performance.
Because Mega Stability Starts at the Cell Level.
With Kolibrik Cell Voltage Monitoring (CVM), you get real-time, per-cell insight into your fuel cell or electrolyzer stack. Detect anomalies early, optimize performance, and extend the lifespan of your system.
Our modular CVM systems are engineered for research labs, pilot setups, and full-scale deployments. Whether you are validating a novel design or ensuring long-term operational integrity, our CVM provides fast, reliable, high-resolution data—the critical input needed for real-time control and predictive maintenance. The entire measurement and control process is driven by the dedicated software Kolibrik CVM − Measurement & Control App.
Purpose-built for hydrogen fuel cells and electrolyzers.
Modular & Stackable
Combine units to monitor large stacks with flexible configurations.
Up to 1280 Channels
High-resolution cell-level voltage monitoring for stacks of various sizes.
Up to 5 V per Cell
Supports a wide range of cell chemistries and applications.
High Sampling Rate
Captures dynamic behavior in real time (up to 500 sps depending on model).
All models are available as scalable Sets. Up to 20 modules can be chained together to match the required number of channels — in increments of 24, 32, or 64 depending on the product family.
Key Features
- Ready-to-use Sets – preconfigured bundles for common stack sizes
- Modular and scalable design – up to 20 modules per system, supporting hundreds of channels
- Per-cell voltage acquisition – real-time data for every cell in the stack
- Compact form factor – easy integration into lab setups or industrial cabinets
- Galvanic isolation – safe operation and signal integrity (typically ≥ 1 kV)
- Support for various cell chemistries – compatible with PEM, SOFC, AFC and alkaline stacks (both fuel cells and electrolyzers)
- Multiple communication options – USB, RS‑485, CAN (depending on version)
- Standalone operation or software integration – with Kolibrik software or custom TCP/IP control

Kolibrik CVM – Measurement & Control App
To operate the hardware, you’ll use the Kolibrik CVM − a dedicated measurement and control app that maps your connected channels automatically and manages real-time stack diagnostics. Just connect the modules, configure your safety limits, and start monitoring.
Automated Hardware Setup
Automatic USB and RS-485 module detection and channel mapping. Fast CAN bus configuration for external systems with one-click DBC file export.
Live Stack Diagnostics
Monitor total stack dynamics and individual cell voltages in real time to visually track critical failure patterns.
Native Python Automation
Write custom Python scripts to automate devices and process recordings directly from the built-in Scripts page with live console output.
Instant Test Reporting
Translate raw measurement data into comprehensive PDF test reports, including data heatmaps and error logs, with one click.
Ensure Longevity and Safety.
