Abstract: The invention relates to the use of 1-alkyl-2-alkyl pyridinium halide (e.g., 1-ethyl-2-methyl pyridinium bromide), 1-alkyl-3-alkyl pyridinium halide (e.g., 1-ethyl-3-methyl pyridinium bromide) or 1-alkyl-3-alkyl imidazolium halide (e.g., 1-butyl 3-methyl imidazolium bromide) as additives in an electrolyte used in hydrogen/bromine cells, for complexing the elemental bromine formed in such cells. The invention also provides an electrolyte comprising aqueous hydrogen bromide and said additives, and processes for operating an electrochemical flow cell selected from the group consisting of hydrogen/bromine or vanadium/bromine cells.
