Product Features

1、0V start, full current with load

Usually, during the overload test of fuel cell, the fuel cell is operated according to the time period specified by the battery manufacturer, or until the battery voltage is reduced to the value specified by the battery manufacturer. If we ask the electronic load to start the test from low voltage or 0V, we will face the problem of high current load due to "0V start".

The "0V start" fuel cell test system avoids this problem and helps us to maximize the evaluation of the cell's VI characteristics. 980 solves this major pain point.

2、Gas Ratio 0-100%

In the fuel cell system, hydrogen is supplied as fuel and oxygen is involved in the reaction as oxidizer to improve the efficiency and stability of the fuel cell - the role of "gas ratio" is highlighted.

Safety: Study the composition of the gas discharged from the fuel system and the gas discharged from the air system, such as composition, volume ratio, characteristics and other information.

Economy: Hydrogen utilization rate affects the reduction of commercial cost of hydrogen fuel cells. Research on hydrogen consumption rate per hour, oxygen consumption rate per hour, air supply per hour and other analytical tests to explore energy efficient fuel control strategies.

Durability: Excessively high live or low gas pressure and flow rate can cause overall fluctuation and affect cell life. Analytical tests help detect fuel cell durability conditions.

3、Desktop type structure

Desktop fuel cell test system is small in size, not picking space, easy to load and carry. The electronic load design is moderate, can meet most of the experimental testing needs, cost-effective.
