Outline of Final Research Achievements

The objectives of this study are to elucidate the active species transport, to identify the factors dominating the charge-discharge efficiencies, and to present the appropriate cell structures and methods for electrolyte control in a redox flow battery. The measurements of charge-discharge characteristics using cells with various structures and current density distributions were conducted. This study also developed the evaluation model of cell performance considering the active species transport in the main-flow and at the electrode surface, and showed effective strategies for operation with high efficiencies.
