Description

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 Scribner 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.
