A promising redox-mediated bromate-ion (BrO 3 − ) based system was investigated through research combined with mathematical modeling, analytical study, and full-cell test to understand the characteristic effect of electrochemical reaction coupled with chemical reaction, called catalytic regenerative reaction (EC'), on the cell behaviors. From the full-cell based discharge test, a unique unsteady behavior induced by the catalytic regenerative reaction was found for the first time, and to understand the underlying physics and nature of the system, theoretical study was conducted through mathematical modeling and analytical method. Three reaction mechanisms (E, EC, and EC') were compared in their characteristic reaction behaviors to understand the nature of each reaction mechanism, and the results were analyzed with respect to reaction time and species concentration at the electrode surface. Furthermore, the effect of actual condition of bromate system (i.e. non-unity stoichiometry and limited amount of bromate) was analyzed at unsteady condition for the first time to understand its characteristic behavior in the actual battery condition. It was found that cell voltage and operation time were increased substantially by the catalytic regenerative reaction, and inclusion of non-unity stoichiometric coefficients induced a significant change in the concentration profiles for reactant and product species, leading to operation time about 4.2 times longer than the unity stoichiometric EC' reaction. As a final step, the effect of catalytic reaction was analyzed in analytical method to define the parameters to control the catalytic reaction, and especially, the relative effect of electrochemical reaction and coupled chemical reaction rates on the autocatalytic reaction was compared through a zone diagram where conditions for pure diffusion controlled and pure kinetic controlled cases were defined.
