Generalization of the Nernst layer model to take into account the difference in diffusivity between the components of the system in bromate reduction in steady-state one-dimensional mode: Current limiting by proton transport

Abstract : The reduction of nonelectroactive bromate anion BrO (3) (-) from acidic solutions while limiting the maximum current by diffusion transport of protons was studied by methods of numerical integration of transport equations. The calculation was performed based on a generalization of the Nernst steady diffusion layer model, in which the choice of the layer thickness for each component of the system is made using the Levich formula and takes into account the difference in diffusivity between the components. This difference in layer thickness was shown to have a significant effect on the main characteristics of the system, such as the maximum possible discharge current, and also the concentration profiles of the components.
