890ZV SOFC Test Load

Name: 890ZV SOFC Test Load - Equilabrium
SKU: SOFCTL890ZV

SKU: SOFCTL890ZV Category: Fuel Cell Test Systems

Rated 0 out of 5

The bench-top Model 890ZV consists of a programmable electronic load, fuel and temperature controls, and data acquisition functions. A built-in power source makes the 890ZV particularly well suited for small single-cell SOFC work for research, laboratory, and educational use.

The 890ZV 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. The 890 Series is supported by the Scribner 885 Integrated Fuel Cell Potentiostat.

Description

Electronic load with two current ranges: 5 / 25 A, 10 V, 50 W
Ramping cell/furnace temperature control
Control signals for two (2) main mass flow controllers plus five (5) additional mass flow controllers
Continuous real-time cell resistance and IR-free voltage measurement by current interrupt
Whole cell voltage plus two high-impedance reference electrode inputs for half-cell data
Optional internal impedance analyzer for EIS and continuous real-time high frequency resistance (HFR)
Cell main terminals and sense inputs tolerant of non-isolated cell
Three (3) internal controllers for anode and cathode humidifier and cell temperatures
Current, voltage or power control mode
Contact inputs for three pressure sensors or alarms
Low voltage output signal to control purge gas valves and to indicate alarm condition
RS485 digital interface for supported external devices
The 890ZV requires a custom or third-party fuel management unit to make a complete test station.
