The 850e is ideal for single-cell and short-stack fuel cell research and university programs, and the powerful FuelCell® software package is included for controlling station operation.


The model 850e Multi-Range Fuel Cell Test System is a complete test station for operation and measurement of PEM/DMFC fuel cells. The 850e combines a computer-controlled instrument (multiple current-range programmable electronic load, fuel and temperature controls, and data acquisition functions) with fuel handling hardware in an integrated bench-top unit. The 850e uses the proven 890e as the basis for the electronic load design. The 850e may be used with a single-cell or small stack, a host computer, and reactant and purge gas supplies.
