| 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).

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. |
