Cation exchange resins are commonly used for polymer electrolyte membranes and DMFC applications as a separator. Usually, the sulfonic acid group qualifies it for use as a proton conductor and it was observed that it can also be useful as a separator and electrolyte in a supercapacitor. Park et al used an all-solid supercapacitor with an electrode containing RUO2 and a Nafion polymer as both separator membrane and electrolyte. The paste of RUO2 and Nafion was applied on carbon paper with a brush and hot-pressed with the Nafion membrane. The cyclic voltammetry was done in the voltage window of 0-1V. The specific capacitance was studied with varying concentrations of Nafion (50, 33, 15 and 7 wt%) in the... 

The constant capacitance model has been applied, in essence, to the adsorption of monovalent cations by montmorillonite in I. Shainberg and W. D. Kemper, Ion exchange equilibria on montmorillonite, Soil Sci. 103 4 (1967). The triple layer model is applied to the same phenomenon by R. O. James and G. A. 

A way to reduce this problem is not to use capacitive electrodes, but rather a faradic structure where a constant potential across the membrane is maintained by the exchange of ions and electrons. In this case, the selective membrane is deposited and patterned on the top of a hydrogel layer containing various cations or anions. This layer, which...
