Overview

Proton exchange membrane water electrolysers (PEMWE) split deionised water into hydrogen and oxygen using a solid polymer electrolyte. In a PEMWE test station, current, temperature, pressure and water flow are precisely controlled so researchers can evaluate efficiency, durability and dynamic response under realistic operating conditions. The PEMWE line from SciTech Korea spans compact university benches through to 200 kW stack systems, providing a complete pathway from materials research to pilot-scale green hydrogen projects.


System Range – From Lab to 200 kW

ScienceGears supplies the full PEMWE portfolio in Australia and New Zealand, including:

  • University Test Station – SE300U-PE, up to 300 W for teaching labs and early-stage R&D.
  • Single Cell Test Stations – SE300-PE, SE500-PE, up to 500 W for detailed MEA and cell characterisation.
  • Stack Test Stations (1–3 kW) – SE1K-PE, SE3K-PE for short-stack evaluation and small demonstrator systems.
  • Stack Test Stations (5–10 kW) – SE5K-PE, SE10K-PE for extended stack durability and operating-strategy studies.
  • Stack Test Stations (30–50 kW) – SE30K-PE, SE50K-PE for advanced scale-up and subsystem testing.
  • Stack Test Stations (100–200 kW) – SE100K-PE, SE200K-PE for high-power R&D close to commercial conditions.


Key Features

Across the range, PEMWE test stations provide:

  • Closed-loop deionised water management with temperature, level, conductivity and filtration control.

  • Back-pressure control for realistic stack testing at elevated pressure.
  • Cell-voltage monitoring channels for tracking individual cell behaviour within a stack.
  • Automation software for control, data logging and alarm handling, with options for integrated AC impedance measurement.

Applications

PEMWE test stations are used for:

  • Development and benchmarking of oxygen and hydrogen evolution catalysts.
  • Optimisation of membranes and membrane–electrode assemblies (MEAs).
  • Durability testing under dynamic load profiles relevant to renewable power.
  • Cell and stack performance mapping prior to system integration.
  • Educational laboratories demonstrating modern hydrogen production technology.

FAQ Section

Q1. What is a PEM water electrolyser and why use it for hydrogen research?
PEM water electrolysers use a solid polymer membrane that conducts protons while separating hydrogen and oxygen. Compared with traditional alkaline systems, PEMWE can operate at higher current densities, respond quickly to load changes and deliver high-purity, high-pressure hydrogen in a compact footprint. This makes them well suited to coupling with renewable electricity sources such as solar and wind.

Q2. Which parameters can a PEMWE test station control and record?
A modern PEMWE test station typically controls current or voltage, cell and stack temperature, anode and cathode pressure, water flow rate and gas outlet conditions. It records these parameters continuously so you can calculate efficiency, degradation rates and dynamic response. Many systems also accept external signals or load profiles to simulate real grid or renewable operating scenarios.

Q3. Are PEMWE test stations safe to operate in a laboratory?
Yes. PEMWE test benches incorporate multiple safety layers, including leak detection, pressure relief, emergency-stop functions, interlocks on key valves and heaters, and software limits on current, voltage and temperature. Correct ventilation and gas handling infrastructure are still essential, but the integrated protections greatly reduce the risk when operated according to the supplied procedures and training.

Q4. What cell and stack sizes can these PEMWE systems support?
These systems support experiments from single laboratory cells up to short stacks, typically in the hundreds of watts to low kilowatt range. Modular designs allow you to start with a research cell fixture and later add stack manifolds, additional thermal control or higher-power supplies, so the same platform can grow with your PEMWE development program.

Q5. How does ScienceGears support PEMWE users in Australia and New Zealand?
ScienceGears provides local consultation to match the test station configuration with your cell hardware, catalysts and research goals. We coordinate installation, basic and advanced training, and can help integrate the bench with potentiostats, EIS modules and custom cells from our broader electrochemistry range. Ongoing support is available for method development and troubleshooting across Australia and New Zealand.
