Abstract

This paper reports an overview of the current state in our research program started in 1995 in collaboration with industries. This program has been aimed at making sure of the feasibility of a thermoelectric convertor for waste heat recovery of gasoline engine vehicle. Major results obtained include: (1) updated ZT-values for Pd,Pt-doped CoSb3 and partially Yb-filled skutterudite antimonides YbyM4Sb12 (M=Co, Fe, Ni; 0<y<1), (2) the performance of thermoelectric convertor using a segmented module of the skutterudites and Bi2Te3-based alloys, (3) a preliminary test of a thermoelectric stack which is the united device of thermoelectric modules and heat exchanger, when properly installed in a 2000cc class automobile.
