890C Fuel Cell Test SystemsComputer Controlled Test Loads
TheNEWmodel 890C high performance Fuel Cell Test Systems are designed to
meet all research and development needs, including impedance measurement. A low
resistance semiconductor based test load and internal 32 bit system processor,
coupled with our FuelCell software, allow precise control a monitoring of all Fuel Cell operatingparameters.
Features: Windows based FuelCell software enables computer control and monitoring of cellpotential, current, power, corrected half cell potentials, half cell resistances, cell iR, gas flow rates and
temperature.
o Multifunction LCD display of cell parameters and diagnostic messages.
o Current interrupt for half and whole cell iR corrected potentials and cell resistances.
o One button polarization, test profile and cyclic loading at any time during a test run.o Ultra low resistance semiconductor loads, operating to 0.2 volts at 250 Amperes.
o Impedance measurements to 10 KHz with ZPLOT and ZVIEW.
o Cell currents to 500 Amperes, stack voltages to 20 Volts.
o Air cooled loads to 1 kW, high power water cooled loads available.

890C Fuel Cell Test Systems
The Scribner Associates model 890C Fuel Cell Test Systems
set a new benchmark of performance. The internal 32 bit processor
monitors all parameters of an operating fuel cell. The advanced loads,
data acquisition electronics and Windows software permit long term
performance testing of a fuel cell or short stack under constant or
varying conditions.
