Outline of Final Research Achievements

This work has examined the possibility of novel thermoelectric devices with high heat exchange capabilities using porous thermoelectric materials. It has been found that some thermoelectric materials such as silicon can be made porous by solidification in hydrogen atmosphere. The diameter of pores and porosity in porous materials fabricated by this technique can be controlled by controlling partial and total pressures of atmosphere composing of hydrogen and argon and a solidification rate. It has been also found that the effective heat transfer coefficient between the thermoelectric material and thermal fluid can be enhanced due to larger specific surfaces.

Academic Significance and Societal Importance of the Research Achievements

世界で生産されるエネルギーの 60% 以上が,「廃熱」として捨てられている.熱電変換は熱エネルギーから電気エネルギーを取り出すという他に類を見ない優れた機能をもち,持続可能な社会の実現に必要な環境維持のために中心的役割を果たすべき要素である.本研究では,熱電材料を多孔質化することにより,熱電材料と熱流体の界面を立体化し,界面熱流束を飛躍的に増大させ,出力を高めた熱電変換システムが構築できることを明らかにした.日本における重要な未利用熱源として知られる産業における温水廃熱や熱排気,温泉,燃料,LNPプラントの冷熱等の流体を熱源に想定したエネルギー回収,発電応用が期待される.
