ZINC-BROMINE BATTERY AND OPERATION THEREOF

摘要

A method and apparatus for maintaining the pH level in a zinc-bromine battery 10 features reacting decomposition hydrogen formed during use of the battery with bromine in the presence of a catalyst 11, which is preferably ruthenium. The catalyst encourages the formation of hydrogen and bromine ions. The decomposition hydrogen is therefore consumed, whereby the pH of the system can remain substantially at a given value.
