890 Fuel cell test loads
The 890 Fuel Cell Test Load is a modular electronic load platform designed for precise control and measurement of single cells and low-power stacks.
It combines programmable loading, integrated system control, and advanced electrochemical diagnosticsโgiving you the flexibility to design a test setup around your experiment, not the other way around.
Flexible Load Control. Integrated Diagnostics. Built for Real Fuel Cell Research.

ADVANCED FEATURES
The 890 is intended for research and development environments where system integration is required. Fuel delivery, safety systems, and full test station configuration are customized based on the application:
-
- Wide dynamic load control โ Multi-range electronic load delivers precise control from low-current diagnostics to high-power operationโwithout sacrificing accuracy at either end.
-
- Integrated System Control โ Directly interfaces with mass flow controllers, temperature control loops, and auxiliary signalsโminimizing external hardware and simplifying setup.
-
- Real-time electrochemical insight โ Measure high-frequency resistance (HFR) and IR-free voltage in real time, giving you immediate visibility into true cell behavior without post-processing.
-
- Impedance & advanced diagnostics โ Optional EIS capability enables analysis of kinetics, charge transfer, and mass transportโall within the same platform.
-
- Half-cell measurement capability โ Supports dual reference electrode inputs, enabling simultaneous whole-cell and half-cell measurements for detailed mechanistic analysis.
-
- Flexible operating modes โ Adapt your testing to real-world conditions with multiple control modes: constant current; constant voltage; and constant power.
-
- Built-in safety & reliability โ Integrated alarms and hardware-level shutdown protections help safeguard both your system and your data.
