| Outline of Final Research Achievements |
(1) A high impedance cell with extremely small electrode area was developed to analyze the phenomenon at the time of applying a high voltage in the porous Electrode/electrolytic solution system.
(2) Phenomena at high voltage pulse application for high impedance cell (distance between electrodes 40 μm) was analyzed by a circuit simulator. It was found that the current at the time of pulse application corresponds to the charging current of the electric double layer and the arc of the high frequency side in the Nyquist plot of the impedance becomes smaller after applying the pulse. In the electrolyte system containing porous electrode - ionic carrier, it was suggested that the electrode structure could be changed by high voltage pulse intrusion.
