Title:
THERMOELECTRIC CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/153359
Kind Code:
A1
Abstract:
[Problem] To provide a thermoelectric conversion device that has a relatively excellent conversion efficiency using a nano-sized through holes. [Solution] According to the present invention, a filmmembrane body 11 has a plurality of nano-sized through-holes 11a provided to pass through the thickness thereof. A pair of electrolytic tanks 13a, 13b accommodate therein an electrolytic solutions 13c and are provided so as to communicate with each other via the plurality of through-holes 11a while sandwiching the filmmembrane body 11 is sandwiched therebetween. A pair of electrodes 14a, 14b are provided to the respective electrolytic tanks 13a, 13b. A temperature adjusting means 15 is provided so as to be capable of heating or cooling at least one electrolytic tank so that a temperature difference is generated in between the electrolytic solutions 13c accommodated in each of the respective electrolytic tanks 13a, 13b. When the temperature adjusting means 15 generates the temperature difference in between the electrolytic solutions 13c accommodated in each of the respective electrolytic tanks 13a, 13b, an electromotive force is generated between the electrodes 14a, 14b.
