Abstract

The Redox Flow Cell

Sebastian Klick

project report

Large capacity, low self-discharge, long lifetime and low cost make redox flow cells ideal energy stores for renewable energy and surplus electricity.

I decided to build such cells, which was challenging as the available equipment at my school was very limited. I built my first redox flow cell from two juice bottles, however, the electrodes were too small leading to low voltage and current. Learing from my mistakes, I built an improved redox flow cell, however, it could only be charged while being shaken. The electrolytes flowed through my cells of the next generation. When I exploited gravity for pumping I could measure a constant voltage. It took many improvements to realize my current cell, which is quite powerful for its size and I am continuing to improve it further.
