Hioki ALDAS-α : EIS Measurement System
Impedance measurement using electrochemical impedance spectroscopy (EIS) method is becoming increasingly important in research on water electrolysis cells, fuel cells, and co-electrolysis process.
Conventional current-voltage (I-V) measurements are commonly used to quantify the cell's overall performance. However, they fall short when it comes to diagnosing the specific underlying causes of performance degradation or change.
EIS is a technique that can quantitatively evaluate and separate complex phenomena within the cell. Analyzing data obtained from EIS measurements offers researchers to explore optimal operating conditions, predict cell lifespan, and verify the effects of changes in cell materials.
Featuring a high-precision current sensor, ALDAS-α delivers exceptionally accurate EIS measurements. It enables much faster cell research and evaluation than is possible with conventional equipment.
