Title:
熱電変換素子及び熱電変換モジュール
Document Type and Number:
Japanese Patent JP4446064
Kind Code:
B2
Abstract:
The present invention provides a thermoelectric element comprising an electrically conductive substrate, a p-type thermoelectric material, and an n-type thermoelectric material; the p-type thermoelectric material being positioned on the substrate via an electrically conductive thermal buffer material, and the n-type thermoelectric material being positioned on the substrate via an electrically conductive thermal buffer material; wherein each thermoelectric material comprises a specific oxide and each electrically conductive thermal buffer material comprises an electrically conductive material having a thermal expansion coefficient between that of the thermoelectric material to which the thermal buffer material is bonded and that of the substrate. The invention also provides a thermoelectric module comprising a plurality of the thermoelectric elements. The thermoelectric element and the thermoelectric module have both a high thermoelectric conversion efficiency and excellent properties in terms of thermal stability, chemical durability, etc.
