| Outline of Final Research Achievements |
This research experimentally indicates the potential of extracting the electrical energy from neutralization reaction of the acidic and basic electrolyzed water, and a fundamental structure of light assisted Electrolyzed-water battery is established. The output voltage of the battery is depending on the difference of the concentration of hydrogen ions between the acidic and basic electrolyzed-water. A maximum output voltage of about 0.6 V (equivalent to about 72% of theoretical value) is realized in our prototype unit cell. We observed that it is possible to adjust the output current of the cell by either controlling the structure of the composite separator-film located between the two electrolyzed water or altering the intensity of light irradiated on it. The formation of highly resistive neutralized water is a major obstacle that cause decaying of the output characteristic as the neutralization reaction proceeds.
