890CL Fuel Cell Test Loads

Computer-controlled instruments include a programmable electronic load, integrated current interrupt iR measurement, up to seven channels of mass flow, three system temperature controllers, and data acquisition in a compact rack mount or bench top unit. Add 880 FRA option for integrated HFR and full range EIS measurement. Use with 892 Data Expansion system to add pressure and temperature channels and/or model 896 Stack Monitor for cell voltage monitoring in a stack.

The model 890CL is a member of the 890C family of versatile fuel cell test systems. These host computer-controlled instruments consist of a programmable electronic load, fuel flow and temperature controls, and data acquisition functions in a compact rack mount or bench top unit. The 890CL series loads are targeted at small to medium size (up to 500W) single fuel cell or low-power stack research for laboratory and educational use.

The model 890CL optimizes cost and size, and offers maximum value from extra hardware features and the powerful FuelCell® software. The 890CL uses the same 32-bit microprocessor as the 890C combined with improved accuracy and thermal drift.

890CL

The FuelCell® host software package is included for operation of the 890CL. The 890CL is for use with a fuel cell (MEA assembly), custom or third-party fuel management unit, and optional model 880 frequency response analyzer (FRA). An optional, extra cost, interface box may be supplied for non-integrated fuel system designs.

  • Constant current, voltage, or power control mode. Dynamic Experiment Editor
  • Automatic shutdown in hardware for overcurrent, undervoltage, overpower, load temperature, and cell temperature conditions
  • Current interrupt cell resistance measurement
  • Multifunction front panel text display with function select button
  • Connector for 890C fuel interface box or Teledyne Medusa fuel unit
  • High impedance whole cell and reference electrode sense inputs
  • Cell main terminals and sense inputs tolerant of non-isolated cell
  • Standard with three internal temperature controllers
  • Analog input/output ports for two mass flow controllers (or DMFC pump, see options)
