850 Fuel Cell Test System

NEW IN 2020:

  • Direct USB Connection
  • Internal Auto Humidifier Drain/Fill Option for rapid dew-point reduction
  • Updated 881 Impedance Analyzer with higher frequency capability.
  • New 885 P/GStat with EIS
  • Voltage & Current control modes – Constant, Scanning & Step-Stair

The model 850 Multi-Range Fuel Cell Test System is a complete test station for operation and measurement of PEM/DMFC fuel cells.  The 850 is ideal for single-cell and short-stack fuel cell research and university programs.

The 850 combines a computer-controlled instrument with fuel handling hardware in an integrated bench-top unit. The 850 uses the proven 890 as the basis for the electronic load design. The powerful FuelCell® software package is included for controlling station operation.
