Redox Flow Battery - Model 1 (RFB1)
Redoxme
S-Stack – Redox Flow Battery Stack
Price: from 3410 EUR
Description
The S-Stack is a configurable flow battery research stack developed for controlled investigation of multi-cell behavior, component interactions, and scale-relevant performance in redox flow battery systems. Its flexible stack architecture enables researchers to bridge the gap between single-cell testing and stack-level validation without complex custom assemblies.
- Configurable from single-cell to nine-cell operation for systematic scale-up studies
- Supports thick, porous electrodes and adjustable compression for realistic battery conditions
- Allows for direct measurement of individual cell voltages on bipolar plates for accurate stack diagnostics
- Graphite-based flow components and chemically stable seals ensure compatibility across a wide pH range
- Stack design balances hydraulic pressure and shunt current control for reproducible multi-cell operation
