Abstract Scope |
In this study, we studied a small thermoelectric power generation system using a Butane cassette cylinder as fuel, which can continuously drive an autonomous robot for a long time. In the SiGe topper thermoelectric module, which is directly heated by catalytic combustion on the Pd/porous alumina layer, the maximum temperature at the high temperature end can reach 900 ºC. The heat conduction loss to the low temperature end is surpressed by 1/5 by using fuel mixture flow from the low temperature end to the high temperature end. We have also developed an early prototype of a thermoelectric power generation system that includes a pair of SiGe topper thermoelectric module, a BiTe exhaust heat recovery thermoelectric module, and all necessary auxiliary equipment. By using this system, we demonstrated successful long-term operation of a wheel-type mobile robot. |
