Traducción generada por IA Hioki E.E. Corporation, headquartered in Nagano, Japan and a world-class test and measurement equipment manufacturer, has developed a specialized ALDAS series of Electrochemical Impedance Spectroscopy (EIS) measurement systems engineered for the research, development, and operational analysis of hydrogen electrolysis cells and fuel cell stacks. The company's ALDAS-Mini (launched February 2025) is a compact, high-performance solution accelerating R&D by completing impedance scans from 10 kHz to 0.01 Hz in approximately 7.6 minutes across 8 channels simultaneously (versus roughly 30 minutes for typical electrochemical instruments), operating seamlessly alongside cell DC power supplies without requiring system modification, while ALDAS-alpha (launched October 2025) provides high-precision impedance measurements for electrolysis and fuel cell R&D, enabling detailed material-level evaluation of catalysts and polymer electrolyte membranes. Hioki's ALDAS-E, a high-voltage/high-current EIS measurement system for MW-class electrolyzers and large fuel cell stacks (launched March 2026, following delivery to JAXA in February 2024 for water electrolysis and Sabatier reaction research), applies industry-first technology combining impedance measurement with high-precision current measurement, enabling evaluation and monitoring of large-scale water electrolyzers and cell stacks under real operating conditions with up to 3,000 channels and 30 measuring instruments supported. As global hydrogen demand approaches an estimated 100 million tons in 2025 per IEA estimates, Hioki continues expanding its ALDAS product family to help engineers shorten evaluation cycles, optimize operating windows, and support the wider adoption of hydrogen technologies toward carbon neutrality.
