Electrochemical behaviors in closed bipolar system with three-electrode driving mode

Here we report the studies on the electrochemical behaviors at a closed bipolar cell which is composed of two separated reaction cells containing a closed bipolar electrode (c-BPE) and its driving electrodes. The influence factors such as the concentration of the reagents, the size and material of the electrodes are studied experimentally and theoretically. And the experimental results fit with the theoretic calculation very well. Significantly, unlike the previous studies focusing on the coupling of the two c-BPE poles, this work also considers the effect of the reaction on the driving electrode on the electrochemical behavior. We believe that this research could,deepen our understanding of bipolar chemistry and be useful for the future c-BPE-based applications. (C) 2016 Elsevier B.V. All rights reserved.
