| Outline of Final Research Achievements |
This research developed a new power generation device that can generate a large output voltage based on the principle of thermopower wave discovered in 2010 by Strano et al. We have succeeded that a thermopower wave device generated 1.0 V, which was 50 times larger than the 20 mV obtained by Strano et al. When the power generation characteristics were examined, the power generation per carbon mass was 0.0035 J/g. It was also found that crystals (deposited film in a quartz tube) generated by burning of powder mixture of carbon-NaH2PO4 (or Na2SO4) was necessary to realize the power generation. It was also found that the how the graphite powders are backed also had a great influence on the power generation.
