Outline of Final Research Achievements |
The quality of the bi-metal interface of a plate-type thermoelectric generator has been improved, and the effective thermoelectric conversion was realized by stacking them. The low-dimensional metallic materials, such as thin wire and thin plates, were joined together by Joule heating, and the quality of the joining interface was evaluated by the techniques with the current or the sound. Oxidizing the bi-metal interface of the plate-type generator was found to be effective to enhance its performance, and the maximum power was estimated theoretically. A theoretical model to predict the performance of the stacked-type thermoelectric generator, which was composed by stacking multiple plate-type generators, has been proposed, and the validity of the model was verified. The maximum power was estimated to be 50uW at the small temperature difference of 40K when 100 plate-type generators were stacked with the Ag past. This is the useful knowledge for the practical use.
