600 PEM Electrolyzer test system

Scribner

The 600 PEM Electrolyzer Test System (ETS) is a next-generation, high-performance bench-top test system engineered for in-depth research and development of Proton Exchange Membrane (PEM) water electrolysis. This all-in-one solution delivers unmatched precision, control, and safety for the diagnostic evaluation a single electrolysis cell.

Equipped with a fully integrated Power Supply, Potentiostat, and Impedance Analyzer (supporting both EIS and HFR), the 600 ETS also features real-time sensors for Product Flow Rate and Cross-over Monitoring, providing researchers with critical insights at every stage of testing.

Our 2nd generation advancements expands automated features to support your long-term testing, and is high-pressure ready!

 

ADVANCED FEATURES

Unlock powerful capabilities designed to simplify complex testing. From automated fluid handling to seamless data connections, every feature is built for efficiency, accuracy, and ease of use:

  • Integrated 100A Power Supply with EIS & HFR — Seamlessly combine electrochemical impedance spectroscopy (EIS) and high-frequency resistance (HFR) for comprehensive insights.

  • Half Cell (R1/R2) Measurements in Power Supply Mode — Get accurate data effortlessly. Our system simplifies half-cell measurements.

  • Dual Channel Mass-Flow Controller (MFC) — Say goodbye to manual rotameters! Our MFC ensures precise gas flow control, with automated safety interventions.

  • Streamlined Cell Cabling —We’ve redesigned the front panel for a simpler, more efficient cabling arrangement.

  • Single USB Connection — Connect effortlessly. One cable, one clear bench.

  • Automated Tank Refill — Unattended operation for electrolyte experiments is now a reality. Let our system handle the details.

  • DI Water Conductivity Probes —Monitor conductivity inside the feed tank via front panel displays and collect data in our FlowCell software.

  • Self-Draining Condensation Tanks — Boost automation and reduce maintenance. No more manual draining.
