Overview
The EZONE CHEMIST TH-500H7 High-Pressure Hydrogen Generator is a compact, membrane-based electrolytic hydrogen production system engineered for continuous, on-demand supply of high-purity hydrogen gas (≥99.999%) at pressures up to 10 MPa (100 bar). Designed specifically for laboratory-scale catalytic hydrogenation, flow chemistry, and in situ reduction reactions, the TH-500H7 employs proton exchange membrane (PEM) electrolysis technology—enabling rapid startup, precise pressure regulation, and zero-carbon operation when powered by renewable electricity. Unlike traditional cylinder-based supply, this generator eliminates storage hazards, reduces logistical overhead, and ensures consistent gas quality without periodic purity verification. Its integrated safety architecture includes real-time hydrogen leak detection, overpressure relief valves, automatic shutdown upon abnormal temperature or current draw, and dual-stage pressure monitoring compliant with ISO 22734-1 for electrolytic hydrogen generators.
Key Features
- PEM Electrolysis Core: Solid polymer electrolyte membrane with noble-metal catalyst anode/cathode assembly for stable, low-maintenance operation and minimal water consumption (≤150 mL/h at rated output).
- High-Pressure Output: Programmable pressure control from 0.5–10.0 MPa (5–100 bar) via digital PID-regulated back-pressure valve; pressure stability ±0.02 MPa over 24 h.
- Gas Purity & Conditioning: Integrated palladium-silver alloy purifier delivers ≥99.999% H₂ (O₂ & H₂O < 0.1 ppm); optional CO scrubber module available for sensitive metal-catalyzed reactions.
- Intelligent Control System: 7-inch capacitive touchscreen interface with embedded PLC logic; supports remote monitoring via Ethernet (Modbus TCP) and local data logging (CSV export).
- Compact Footprint & Modular Design: Dimensions 480 × 520 × 860 mm (W × D × H); front-access service panel enables field replacement of PEM stack and desiccant cartridges without tools.
- Safety-Certified Architecture: CE-marked per EN 61000-6-4 (EMC) and EN 61000-6-2 (immunity); conforms to IEC 60079-0 for non-explosive zone classification when installed per manufacturer’s ventilation guidelines.
Sample Compatibility & Compliance
The TH-500H7 is compatible with standard Swagelok® 1/4″ VCR fittings and integrates seamlessly with Parr reactors, Corning AFR flow systems, ThalesNano H-Cube® interfaces, and custom-built hydrogenation manifolds. It meets essential regulatory requirements for research-grade gas generation: compliance with ISO 8573-1:2010 Class 1 for particulate and oil content, and ASTM D7612-22 Annex A1 for trace impurity profiling in hydrogen used in catalysis. While not certified for GMP manufacturing environments, its audit-ready event log (including timestamped pressure/temperature/current records) supports GLP-aligned documentation practices. The unit is supplied with a full Declaration of Conformity and factory calibration certificate traceable to NIM (China National Institute of Metrology).
Software & Data Management
Firmware v3.2 includes embedded data acquisition supporting up to 16 configurable parameters (e.g., cell voltage, coolant temperature, outlet pressure, total H₂ volume) logged at user-defined intervals (1 s–1 h). Exported CSV files contain ISO 8601 timestamps and SI-unit annotations, enabling direct import into MATLAB, Python (pandas), or LIMS platforms. Optional EZONE Connect software (Windows/macOS) provides live dashboard visualization, alarm configuration (email/SNMP), and firmware update capability. All operational logs retain immutable timestamps and are stored in non-volatile memory—even during power loss—ensuring integrity for internal process reviews or regulatory audits.
Applications
- Catalytic hydrogenation of unsaturated organic compounds (alkenes, alkynes, nitroarenes, imines) under controlled pressure in batch or continuous-flow reactors.
- In situ generation of reactive hydrogen species for metal-free reductions and transfer hydrogenation studies.
- Calibration and challenge testing of hydrogen sensors (e.g., electrochemical, thermal conductivity, MEMS-based) across defined pressure and flow ranges.
- Feed gas source for hydrotreating model studies in heterogeneous catalysis research using fixed-bed microreactors.
- Supporting green chemistry initiatives by replacing cylinder-derived H₂—reducing Scope 1 emissions and eliminating cylinder transport logistics.
FAQ
What is the maximum continuous hydrogen output rate at 10 MPa?
The TH-500H7 delivers up to 500 mL/min (STP) at rated pressure, with flow rate modulated proportionally to applied current (0–30 A DC); actual volumetric delivery decreases slightly with increasing backpressure due to gas compressibility.
Is deionized water the only required consumable?
Yes—only ASTM Type II deionized water (resistivity ≥1 MΩ·cm) is needed; no KOH or other electrolytes are used, eliminating corrosion risk and simplifying maintenance.
Can the unit be integrated into an automated reaction platform?
Yes—digital I/O (4× isolated inputs, 4× relay outputs) and Modbus TCP enable bidirectional communication with PLCs or reactor control systems for coordinated start/stop, pressure ramping, and fault interlocking.
What is the expected PEM stack lifetime under typical lab usage?
Based on accelerated life testing at 80% rated load, mean time between replacements is ≥12,000 operating hours (≈1.4 years continuous use); field data from academic users shows median stack longevity of 18–24 months.
Does the generator comply with FDA 21 CFR Part 11 requirements?
No—while audit trails and electronic records are generated, the TH-500H7 is not validated for Part 11 compliance; it is intended for R&D use, not regulated pharmaceutical manufacturing.
