Outline of Final Research Achievements |
In order to create innovative electrochemical capacitors using anion exchange membrane as polymer electrolyte for use in fuel cells, we investigated effects of the membrane thickness and interface structure with activated carbon electrodes on electrochemical properties of the electric double layer capacitor (EDLC) cell. By optimizing thickness of electrolyte membrane and electrode/electrolyte interface structure, we succeeded in constructing an excellent EDLC cell with better rate-capability and lower cell resistance, compared with a cell using KOH solution. Furthermore, it was clarified that the electrolyte membrane had a good adaptability to a 2.5 V-class asymmetric capacitor composed of activated carbon and manganese-nickel oxide solid solution electrodes.
