title: Reply to "Comment on 'Modeling of electrode polarization for electrolytic cells with a limited ionic adsorption' ".
abstract: The dielectric properties of dilute electrolytic solution cells have been measured in a low-frequency region, and the dielectric spectra have been analyzed in terms of space-charge polarization by using the Nernst-Planck (NP) model in the presence of ionic adsorption on electrodes [Phys. Rev. E 88, 032406 (2013)]. In the NP model, the internal electric field of the cell is considered to be approximately equal to the external field. In a Comment by Alexe-Ionescu et al. [Phys. Rev. E 89, 056401 (2014).] on our paper [Phys. Rev. E 88, 032406 (2013)], they claim the invalidity of the NP model and the necessity of the conventional Poisson-Nernst-Planck (PNP) model for the data analysis. Their criticisms are, however, originated from a viewpoint for determining the internal electric field, that is different from our approach. In this Reply, we show the validity of the NP model referring to our previous paper in which the conventional PNP model has been modified so as to correctly describe the actual internal field.
