Hydrogen Generator
Benchtop electrolytic hydrogen generator producing ultra-pure hydrogen (≥99.999%) at 600 ml/min flow rate for analytical instrumentation and research applications.
The ConductScience Hydrogen Generator provides on-demand hydrogen gas production through electrolytic water splitting for analytical instrumentation and research applications. This benchtop unit delivers ultra-pure hydrogen (≥99.999%) at a continuous flow rate of 600 ml/min with precise pressure control from 0 to 0.4 MPa.
Engineered for laboratory environments, the system operates at low noise levels (≤55 dB) while maintaining consistent gas purity and flow characteristics. The compact design (430×220×380 mm) integrates safety features including automatic pressure relief at 0.5±0.05 MPa to ensure reliable operation in analytical workflows requiring carrier gas or fuel applications.
How It Works
The hydrogen generator employs polymer electrolyte membrane (PEM) electrolysis to split deionized water into hydrogen and oxygen gases. An applied electrical current drives the electrochemical reaction at the cathode (2H₂O + 2e⁻ → H₂ + 2OH⁻) producing ultra-pure hydrogen gas. The proton exchange membrane selectively allows hydrogen ions to pass while blocking other gases and contaminants.
Internal pressure regulation maintains output pressure between 0-0.4 MPa through automated control valves. A safety relief system activates at 0.5±0.05 MPa to prevent overpressurization. The electrolytic cell design eliminates the need for external hydrogen storage while providing continuous on-demand gas generation.
Integrated purification removes trace moisture and oxygen contaminants, achieving hydrogen purity levels of ≥99.999%. The system operates on standard laboratory power (AC220V/110V, 50Hz/60Hz) with low acoustic output (≤55 dB) suitable for analytical laboratory environments.

This hydrogen generator offers ultra-high purity (≥99.999%) with 600 ml/min flow rate and precise pressure control up to 0.4 MPa. The low-noise operation (≤55 dB) and compact design make it suitable for analytical laboratories requiring continuous, high-quality hydrogen supply.
Practical Tips
Verify hydrogen purity periodically using gas chromatography or dedicated purity analyzers to ensure specifications are maintained.
Why: Purity verification confirms electrolytic cell performance and identifies potential contamination sources.
Replace deionized water regularly and monitor water quality to prevent electrolytic cell contamination.
Why: Water quality directly affects hydrogen purity and system longevity by preventing mineral buildup in the electrolytic cell.
Allow 10-15 minutes warm-up time before connecting to analytical instruments to achieve stable flow and pressure.
Why: System stabilization ensures consistent gas delivery and prevents pressure fluctuations during critical analytical runs.
Install hydrogen detectors in the laboratory area and ensure adequate ventilation around the generator.
Why: Hydrogen safety monitoring provides early warning of potential leaks and maintains safe laboratory conditions.
Check all gas connections for leaks if pressure drops or flow rates decrease unexpectedly during operation.
Why: Leak detection prevents gas loss and ensures consistent instrument performance while maintaining safety standards.
Monitor system pressure and flow rates during analytical runs to identify potential issues affecting measurement reproducibility.
Why: Consistent gas delivery parameters are critical for maintaining analytical precision and method validation requirements.
Keep spare gas line fittings and tubing available for quick replacement during routine maintenance.
Why: Ready availability of replacement parts minimizes analytical downtime and maintains laboratory productivity.
