840 1kW Fuel Cell Test System

The 840 Advanced Fuel Cell Test System is a turn-key test station for fuel cell research and university education programs. The 840 combines a computer-controlled instrument with fuel handling hardware in an integrated bench-top unit. The 840 is designed for use with small to large single cells or short stacks.

The Model 840 is targeted for applications requiring gas flow rates up to 12 SLPM and is based on the time-tested 850 series of turn-key fuel cell test stations. The 840 features dual range anode and cathode mass flow controllers for wide range flow control which is ideal for RH cycling. Also included are input selector valves and a 16-channel data acquisition module for additional voltage and temperature measurements.

The Model 840 uses Scribner’s 890 Multi-Range Electronic Load for accurate, wide-range current measurement. And, the Model 840 comes with FuelCell^®, the industry’s most powerful and user-friendly application software for controlling station operation and experimentation.
