for Water Electrolysis Cell
What is ALDAS-E？
HIOKI offers ALDAS-E, a revolutionary measurement solution for evaluating water electrolyzers.
The ALDAS method enables impedance measurement of cells and stacks and logging of changes in impedance values during active conditions when a water electrolyzer operates at high currents.
What is the ALDAS method？
The ALDAS method is a measurement method that applies HIOKI’s specialized impedance measurement technology used in AC-IR measurement of lithium-ion batteries and high-precision current measurement technology required in the evaluation of power electronics such as inverters.
The ALDAS system’s wide voltage and current measurement range and high noise immunity make it helpful in evaluating cells operating with wide current and voltage ranges. Hence, ALDAS is useful to assess cell characteristics, monitor the condition of fuel cells in operation, and diagnose cell degradation under actual load conditions for large-scale hydrogen production, FCVs, HDVs, and other fuel cells.
What ALDAS-E offers you…
1. Characterization of materials for bigger-capacity Electrolysis cells
2. Comparison between platinum Loading and impedance, regarding MEA
3. Long-term membrane degradation evaluations during water electrolyzer is in operation
