Title:
セグメント型熱電発電モジュール
Document Type and Number:
Japanese Patent JP6820556
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a segmented thermoelectric power generation module which is obtained by joining clathrate compounds of different types, and which has a high conversion efficiency. A segmented thermoelectric power generation module according to the present invention is composed of a p-type thermoelectric conversion element and an n-type thermoelectric conversion element. The p-type thermoelectric conversion element uses a type 8 clathrate compound on the low temperature side, while using a type 1 clathrate compound on the high temperature side; and the n-type thermoelectric conversion element uses a type 2 clathrate compound on the low temperature side, while using a type 1 clathrate compound on the high temperature side. Meanwhile, a type 9 clathrate compound may be used on the high temperature side of the n-type thermoelectric conversion element.
