| description | Experimental validation of the current distribution for actual cell geometries is an important complement to modeling. In this work, the combination of a segmented electrode in a miniaturized Hull Cell with a synchronous monitoring of the current response in each segment is proposed as a novel experimental set-up. The high frequency monitoring of the current response to potential steps is investigated as a mean to access the temporal and spatial evolution of current distribution. The corresponding primary current distribution was measured using a ferricyanide/ferrocyanide alkaline electrolyte, confirming the prediction from Laplace's equation. In addition, the experimental set-up allowed the identification of the transition time from primary to tertiary current distribution regimes. |
