Hioki ALDAS-E : EIS Measurement System
The Hioki ALDAS-E is an EIS measurement system optimized for large-scale kilowatt to megawatt-class electrolyzers and fuel cells. This in-situ capability facilitates the exploration of optimal operating points and provides data-driven insights into the internal state and degradation mechanisms of the cell stack, and unlike conventional methods, it supports impedance analysis of large stacks during active demonstration and commercial operation.
Features
- EIS measurement of kW to MW class stacks in actual operation
- Simultaneous measurement of stack and cell with up to 48 channels
- High-speed EIS measurement
- Stable and high-precision measurement down to low frequency range
- Easy connection to existing electrolyzers and FC systems
