Product description
The E500 series is designed to provide a precise and reliable test platform for PEM/ALK/AEM single cells and material-level evaluations. The system comprises a circulation unit, nitrogen purge module, pressure regulation unit, gas–water separation module, gas analysis pretreatment unit, PLC data acquisition and control unit, HMI, and safety monitoring. It runs on in-house test software and supports polarization curve, electrochemical measurements, online H2 concentration monitoring, sensitivity testing, durability testing, hydrogen production energy-efficiency and quality testing, and lifetime evaluation.

Product features
Testing standards: Supports relevant electrolyser testing requirements proposed by the EU JRC.
Precision and reliability: circulation flow accuracy 1% F.S.; temperature ±1°C; conductivity ≤0.5 μS/cm; gas flow ±(0.8%Rdg+0.2%F.S.).
Desktop layout: L650×W480×H700 mm.
Dedicated fixtures: 5 cm², 16 cm², 25 cm².
Automatic backpressure: max 2 barg, accuracy ±2 kPa.
Electrochemical integration: Supports EIS/CV and related tests.

Electrochemical and online testing capabilities
1. Direct EIS testing within the system without an external potentiostat; supports up to 10% EIS under DC up to 200 A.
2. Online HFR measurement.
3. Online interrupted-current internal resistance tests.
