Product Functions

  • Capable of evaluating fuel cells fitted with many types of reference electrodes. Supports detailed evaluation and analysis of anode and cathode characteristics (As-510-4 Fuel Cell Analyzer)
  • Equipped with input terminals for three-terminal voltage measurement (+, -, and REF), the As-510-4 can simultaneously measure the voltage between terminals and isolated resistance (IR). It incorporates new circuitry to provide support for a wide variety of reference electrode types (As-510-4 Fuel Cell Analyzer)
  • When combined with the optional three-terminal impedance measuring unit, the As-510-4 can measure impedance between terminals and supports continuous measurements without having to change connections (As-510-4 Fuel Cell Analyzer)
  • Compatible with constant-current/constant-voltage operation and supports Open Circuit Voltage (OCV) measurement (As-510-4 Fuel Cell Analyzer)
  • Simultaneous measurement of impedance between three voltage detection terminals (As-510-IMU Impedance Analyzing Unit)
  • Four input channels enable use of one current as a reference while measuring the voltage response at up to three points. The channels are insulated from each other and any point in the cell can be measured (As-510-IMU Impedance Analyzing Unit). Detailed analysis of the measurement results can be performed with As-510-Z Fuel Cell Analyzing Software (Option)
  • As-510-S4 System Software handles all aspects of using the fuel cell evaluation system, including control of individual devices, graphical display of measurement results and storing data (See photo section)
  • Trend Graph, Tafel Plot, Cole-Cole Plot and Voltammogram plots are supported by As-510-S4 (See photo section)
  • Supports DC analysis via cyclicvoltammetry or linear sweep voltammetry as well as measurement of MEA electrochemical impedance (EIS) when power generation is not occurring. It performs measurements essential to identifying causes of MEA deterioration, which can affect fuel cell performance (As-510-CVM Electrode Analyzing Unit (Option)). Detailed analysis of the measurement results can be performed with As-510-Z Fuel Cell Analyzing Software (Option)
  • The optional As-510-Z Fuel Cell Analyzing Software performs automated equivalent circuit estimation by means of a proprietary algorithm that uses curve fitting on the impedance measurement results. This allows quantitative evaluation and analysis of the fuel cells’ internal impedance. It also calculates the catalyst active area with a voltammogram derived from measurements of electrode characteristic. This allows a quantitative assessment of the catalyst activation level
  • The As-510-Z Fuel Cell Analyzing Software supports the following circuit elements: R, L, C, R//C, R//L, R//L//C, Zw, CPE, R.Zw//C, R.CPE//C, R//CPE
  • The As-510-C is a cell equipped with a reference electrode and supports three-terminal measurement using As-510-4. Any MEA can be bracketed in order to measure its characteristics
