This study presents the fabrication of an oxide-based thermoelectric power generation module using layer-structured p-type Ca3Co 4O9 and n-type (ZnO)7In2O 3 legs. The potential for development and effective use of high power density thermoelectric generation system is investigated in terms of its power per area, the temperature conditions, and the number of p-n couples. The significance of the manufacturing factors including contact between legs and electrodes are discussed. The thermoelectric figure of merit values of the p-type and n-type legs at 1100 K were 0.55 × 104 K1 and 1.35 × 104 K1, respectively. The maximum power obtained was 423 mW with the 44 p-n couples module, under the thermal condition of a hot-side temperature of 1100 K and a temperature difference AT= 673 K. Crown
