Research on a Zinc Flow Cell Prototype
Abstract:
With the purpose of development of zinc flow cells/batteries, a fundamental study on the cell plate stress distribution, power generation performance and the changes of the internal material before and after the test was carried out in a single zinc flow cell system. The results show that locations between the main channels and the reaction zone area are prone to leakage, the cell power performance is mainly influenced by ohmic losses, the total generating capacity depends on the zinc quantity in the cells and the quantity of electrolyte in the circulatory system, the zinc granule surface becomes more microporous when it comes to the power stage, and the catalytic layer repeated wetting and drying may be the important reason to influence the cycle life. This research is basis for development of higher power and larger capacity zinc flow cell systems.
