Charge transport in poly(oxoammonium cation/nitroxyl radical) redox gels was investigated by chronoamperometry on the basis of an infinite-diffusion model without a volume change during the redox reaction and a limit of the diffusion distance by means of fabricating the bulk solid gels. Charge transportation in the redox gels was found to be dominated by the mobility of electrolyte anion rather than the concentration of redox centers. Furthermore, the ionic conductivity of the redox gel was estimated to be almost one third of that of the liquid electrolyte. The result indicates that larger ionic conductivity in the gel also brings faster charge transportation through the redox centers.
