Abstract

Thermally stable oxide thermoelectric elements and generator was fabricated for the purpose of decomposition of NO_x in the exhaust gas using electrochemical cell by thermoelectric power assist from waste heat energy. The electrical and thermal properties of n-type ZnO based thermoelectric oxide materials were improved by compositional and structural control method in polycrystalline materials. Approximately 40 mW/cm², electric power was generated by using Al-doped ZnO/Bi-doped Ca₃Co₄O₉ thermoelectric oxide cell at dT=500 K in air. Furthermore, thermoelectric and electrochemical cell combined system was fabricated on the 8 mol%Y₂O₃ stabilized ZrO₂ (8YSZ) ceramics plates.
