Analysis of Potential Distribution at the Boundary with the Membrane inside a Flow-by Porous Electrode at Various Currents. Part I. Modeling

详细

The potential profiles at the boundary with the ion-exchange membrane and near the current feeder and the current and concentration profiles of the target electroactive component along the solution flow in the galvanostatic mode are calculated at various current loads using a simplified model of porous electrode. From the analysis of the calculated results, it follows that the potential profiles vary significantly depending on the current and the presence or absence of a side reaction. The results can be used for preliminary estimation of electrolysis mode, which provides the highest efficiency of porous electrode operation.
