The Model 890ZV consists of a programmable electronic load, fuel, and temperature controls, and data acquisition functions in an integrated bench-top unit. A built-in power source makes the 890ZV particularly well suited for small single-cell SOFC work for research, laboratory, and educational use. *NEW* The 890 Series is now supported by the SAI 885 Integrated Fuel Cell Potentiostat!

 

The 890ZV, like earlier models, is optimized for cost and size, and offers extra hardware features and Scribner Associates’ FuelCell® software.

The 890ZV is typically used with a SOFC fuel cell, a suitable furnace, and a fuel management unit. It is available with an optional internal model 880 Frequency Response Analyzer (FRA). An interface box may be purchased for non-integrated fuel system designs.

FuelCell®Software Capabilities

  • Apply and control a current, voltage, or power load on the fuel cell under test
  • Measure fuel cell impedance at full operating current (requires additional hardware)
  • Operate the purge and fuel gas streams for a PEM type fuel cell
  • Control fuel cell test fixture and gas humidification temperatures
  • Scale fuel cell parameters for area, current, and operating voltage
  • Monitor performance over a wide range of time intervals
  • Display data using a wide variety of axis formats
  • Observe fuel cell performance through cell resistance and Tafel slope measurement
  • Save data files and experimental setup parameters to disk
  • Run with, or without, fuel gas control
  • Select from 13 preset graphs or create graphs from any of 11 variables and time
  • Data easily imported into a wide range of spreadsheets such as Microsoft Excel
  • Built-in impedance measurement software
A demo version of the FuelCell®program is available. The demo version is a fully featured copy of FuelCell® which may be installed so that it requires no instruments.

Contact us for additional information about load sizes, performance data, pricing, and receiving a demonstration disk or complete specifications for the test load systems and FuelCell® software package.
