AB  - The changes in capacitive behavior of C/H(x)RuO(y) composite material prepared by impregnating the Vulcan (R) XC 72R carbon black with oxide sols of different particle size are investigated as the electrolyte penetrates through the thin layer of the Nafion (R)-covered composite. The techniques of cyclic voltammetry and electrochemical impedance spectroscopy are used. Results of the investigation reveal the influence of potential cycling and the exposure time to the electrolyte on registered capacitive characteristics of composite. The cycling in a wide potential range causes the decrease in energy storage ability which depends on oxide particle size. Impedance measurements, however, show that the ability initially decreases and subsequently increases during exposure to the electrolyte as the consequence of the presence of Nafion (R) top-layer. Due to wettability and resistance issues, Nafion (R) top-layer can affect the pseudo-capacitive characteristics, and the energy storage ability of the composite consequently decreases.

AB  - The capacitive properties of titanium electrodes with an active porous RuO2 coating were investigated in H2SO4 and NaCl solution by cyclic voltammetry and electrochemical impedance spectroscopy. Electrodes with two different masses of coating (thin and thick coating) were prepared from an ink suspension of the oxide synthesized by hydrolysis of ruthenium-ethoxide in ethanolic solution. The capacitive characteristics were found to be dependent on the coating mass and the electrolyte composition. It was shown that the impedance data of the prepared electrodes, registered at the open circuit potential, can be interpreted by a transmission line model of the equivalent electrical circuit. In this interpretation, the number of parallel branches containing resistor and capacitor in series is different for thin and thick coatings and in different electrolytes. More branches were required to describe the impedance behavior of the thick coating and to simulate the impedance data in NaCl solution. Simulation of the impedance data with the transmission line model of the equivalent circuit was also used to analyze the distribution of capacitance throughout the porous coating. The simulation indicated a more pronounced contribution of the capacitance of the outer coating layer to the total coating capacitance in the case of the proton-rich electrolyte. On the other hand, the presence of chloride ions in the electrolyte promoted a charging process at the inner coating surface, which is hardly accessible to the electrolyte.
