Fuel Cell Testing System
Fuel Cell Impedance Measurement System
As-510 series

Imprdanece Analyzing Units   As-510-IMU
Supports simultaneous measurement of impedance between three voltage detection terminals.

This optional unit brings together NF’s technology from the field of frequency response analyzers into a single package for measuring fuel cell impedance. It allows measurements required for more detailed analysis. The As-510-IMU supports simultaneous measurement of impedance between three voltage detection terminals. When used with a short stack, not just the entire cell, but up to three test points (a single cell in a stack, multiple cells in a stack, etc.) can be measured simultaneously.

Features

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, any point in the cell can be measured.

Detailed analysis of the measurement results can be performed with Fuel Cell Analyzing Software (As-510-Z, sold separately).


Main Specifications

Setting frequency range: 0.1 mHz to 100 kHz
Oscillator output waveform: Sine wave
Oscillator signal amplitude: 0 to 20 Vp-p (with output terminals open)
Number of analyzer channels: 4
Analysis items: CH1/CH2, CH1/CH3, CH1/CH4
(System software is required in order to use the optional As-510-IMU.)




Electrode Analyzing Unit   As-510-CVM
For measuring electrode characteristic.

This optional unit supports DC analysis via cyclic voltammetry or linear sweep voltammetry as well as measurement of MEA electrochemical impedance (EIS) when power generation is not occuring. It performs measurements essential to identifying causes of MEA deterioration, which can affect fuel cell performance.

Features

Supports measurement via cyclic voltammetry or linear sweep voltammetry.

Supports Electrochemical Impedance Spectroscope (EIS)

Detailed analysis of the measurement results can be performed with Fuel Cell Analyzing Software (As-510-Z, sold separately).

Main Specifications

Measurement items : Cyclic voltammetry, linear sweep voltammetry, EIS
Measurement range :
Voltage: ±4V, 1mV resolution
Current: ±4A, 10µA resolution
EIS operating frequency range : 0.1mHz to 50kHz
(System software is required in order to use the optional As-510-CVM.)
