Experimental 3D concentration profiles along an electrodialysis channel reveal a strong effect of natural convection

Electrodialysis and electrodeionization separate ionic components from processed water solutions by applying a DC electric field on a stack of ion-exchange membranes. The ion separation indicates ionic concentration changes along the channels in the membrane modules. Simultaneously, concentration polarizat...

The Effect of Input Parameter Variation on the Accuracy of a Vanadium Redox Flow Battery Simulation Model

Accurately predicting battery behavior, while using low input data, is highly desirable in embedded simulation architectures like grid or integrated energy system analysis. Currently, the available vanadium redox flow battery (VRFB) models achieve highly accurate predictions of electrochemical behavior...

Semi-Continuous Desalination and Concentration of Small-Volume Samples

Electrodialysis is an electric-field-mediated process separating ions exploiting selective properties of ion-exchange membranes. The ion-exchange membranes create an ion-depleted zone in an electrolyte solution adjacent to the membrane under DC polarization. We constructed a microfluidic system that uses t...

Electric Potential Profiles in a Model Single-Path Electrodialysis Unit

Electrodialysis is an important electromembrane separation process anticipated to play a significant role in developing future technologies. It produces ion-depleted and ion-concentrated product streams, intrinsically suggesting the formation of spatial gradients of relevant quantities. These quantities affect ...

New organic-air flow fuel cell and electrolyser for stationary energy storage

In this work, we propose an innovative hybrid flow battery using anthraquinone disulfonic acid (AQDS) based negolyte in an AQDS-oxygen fuel cell and AQDS-oxygen electrolyser as a discharging and charging devices, respectively. The performance of the system is studied under defined conditions...
