Gantner Instruments at Hydrogen Expo Italy 2025

Precision Data Acquisition for Italy’s Hydrogen Transition
Italy’s extensive renewable energy infrastructure and robust natural gas networks position it uniquely for leadership in Europe’s hydrogen economy. Leveraging these assets effectively requires precise and reliable measurement solutions across the entire hydrogen value chain—from electrolysis-driven production to storage, distribution, and fuel cell applications.

High-Voltage Isolation Measurement for Electrolyzers and Fuel Cells

Accurate monitoring of high-voltage electrolyzer and fuel cell stacks demands specialized measurement capabilities. Standard DAQ systems often lack the necessary isolation and synchronization to handle DC voltages up to 1500 V without introducing noise, risking measurement integrity.

Gantner Instruments’ Q.series High-Voltage Isolation Modules directly address these challenges, providing reliable, high-resolution measurements across multiple channels. Each channel is galvanically isolated, eliminating ground loops and electrical interference, thus ensuring precise voltage and current readings even under rapidly changing load conditions. These modules integrate smoothly into existing test setups, enabling comprehensive stack-level monitoring from early-stage R&D through full-scale deployment.

Advanced EIS for Enhanced Fuel Cell & Electrolyzer Diagnostics

Proactive maintenance and efficient operation of hydrogen technologies rely heavily on understanding internal electrochemical processes. Traditional monitoring often fails to detect subtle degradation issues until performance significantly deteriorates.
Gantner’s powerful Electrochemical Impedance Spectroscopy (EIS) system provides real-time diagnostics across a comprehensive frequency range—from millihertz to tens of kilohertz—capturing detailed impedance spectra that pinpoint catalyst effectiveness, membrane health, and electrode performance issues at the earliest stages. By integrating seamlessly with your existing data acquisition infrastructure, Gantner’s EIS platform facilitates predictive maintenance routines and advanced analytics, significantly reducing downtime and extending the operational lifespan of your fuel cells and electrolyzers.

Cryogenic Monitoring for Liquid Hydrogen Applications

Accurate cryogenic temperature measurement is critical to ensure the safe and efficient storage of liquefied hydrogen (LH₂). Standard measurement techniques can introduce inaccuracies due to sensor self-heating, non-linearities, or thermal drift, risking operational safety and efficiency.

To address this, Gantner Instruments developed the specialized Q.series X A105 CR cryogenic measurement module. Optimized specifically for LH₂ environments, this system supports high-resistance cryogenic sensors (including platinum RTDs, silicon diodes, and Cernox®), providing ultra-low excitation current and precision 24-bit resolution to ensure accurate, real-time temperature readings. By eliminating common cryogenic measurement errors, our technology helps safeguard structural integrity and minimize hydrogen boil-off losses.
