| Fuel Cell Analyzer As-510-4 |
|
|
Capable of evaluatiing fuel cells fitted with many types of resference electrodes.
Supports detailed evaluation and analysis of anode and cathode characteristics. |

 |
Features |
|
|
|
|
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.
|
|
NF’s exclusive step method supports IR measurement with
high reproducibility, while also supporting the current inter-
ruption method.
|
|
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.
|
|
Three ranges (10A, 50A, and 100A), and capacity of up to
20V or 100W.
|
|
More precise current and voltage settings and more accurate
measurement provide improved reproducibility.
|
|
Compatible with constant-current/constant-voltage operation,
and supports Open Circuit Voltage (OCV) measurement.
|
|
Equipped with a GPIB interface.
