Stack Test Station (1–3 kW) – Alkaline Water Electrolyser (SE1K-AL / SE3K-AL)

Overview

The SE1K-AL / SE3K-AL Alkaline Stack Test Station is a compact, instrumented platform for controlled testing of alkaline water electrolyser (AWE) single-cells and small stacks, enabling reproducible evaluation of performance, stability, and gas quality under laboratory and pilot-style operating conditions.

Working principle

The station supplies DC power for electrolysis (typically galvanostatic / constant-current control for the electrolyser and constant-voltage operation for stack-level testing), while managing electrolyte handling and gas conditioning. An integrated electrolyte circulation loop supports alkaline operation (e.g., KOH-based electrolyte) with heating/cooling capability, liquid-level monitoring, and automated fill options. Generated gases pass through gas–liquid separation, cooling/condensation trapping, and optional drying + dewpoint monitoring before measurement and safety checks.

Key features and specifications

• Models / power range: SE1K-AL (~1 kW) and SE3K-AL (~3 kW)
• Cabinet dimensions: 800 (W) × 1300 (D) × 2000 (H) mm
• Gas flow measurement (typical): H₂ up to ~5 slpm (1 kW) / ~15 slpm (3 kW); O₂ up to ~2.5 slpm (1 kW) / ~7.5 slpm (3 kW)
• Mass flow measurement turndown: 100:1 (typical configuration)
• Liquid temperature control: RT to ~95 °C (application dependent)
• Back-pressure control: automated control (commonly up to 10 bar, with higher-pressure options depending on configuration)
• Diagnostics (optional): multi-channel cell voltage monitoring (CVM) and optional AC-impedance / HFR capability (10 mHz to 10 kHz range where configured)
• Safety & automation: gas detection, alarms, shutdown logic, and data acquisition with configurable software workflows
  
  

Compatibility and applications

Ideal for AWE stack development, electrode/catalyst validation at stack scale, balance-of-plant studies (flow/temperature/pressure), durability testing, and gas crossover/quality monitoring. Researchers often use this station after early screening with potentiostats and benchtop electrochemical cells, and alongside broader energy test stations and hydrogen research instrumentation available via ScienceGears.
