Development of Zinc air redox flow battery especially on designing a single cell, stack and also its system.
In order to operate Zinc air redox flow battery, there are important components including bipolar plate, membrane, catalyst, zinc slurry and others, which needs to be researched. Hence, designing a single cell for redox flow battery is important as each component can be evaluated by single cell performance. Furthermore, after accumulating many experimental data, it is possible to scale up the single cell and also make it stackable for wider application.
At the same time, to make sure experimental results are reliable and trustworthy, it is also very important to construct an appropriate system for redox flow battery. Good system not only make battery durable but also efficient.
