FC(Fuel Cell) Impedance Measurement System

Quick info


The KFM2150 system is a fuel cell impedance measurement system configured with an FC impedance meter KFM2150 and an electronic load PLZ-4W series. Combination of KFM2150 and PLZ-4WA series (0V input type) supports impedance measurement for single cell of fuel cell.
In addition to impedance measurement with AC impedance method, KFM2150 system provides IR measurement with current interrupt method.
Application software enables test for each characteristic of fuel cell such as I-V characteristics, Constant Current characteristics, Current Interrupt method and Cole-Cole plot by the AC impedance method. Moreover, each test can be performed in a specified order.Note: Only FC impedance meter KFM2150 cannot be operated.KFM2150 system needs to be combined with PLZ-4W series and calibrated.


  • Capable of measuring impedance in the frequency range from 10 mHz to 20 kHz.
  • Parallel operation by same model of PLZ-4W series enhances current capacity and power capacity.
