【 摘 要 】

This paper compares the performance of a group of organic and inorganic phase change materials for a heat storage thermoelectric energy harvesting device. The device consists of thermoelectric generators and a closed container filled with a phase change material. One side of the generators is mounted on the aircraft fuselage and the other to the thermal mass. The group of inorganic and organic phase change materials was tested across two temperature ranges. These ranges are defined as "positive" and "negative", with the former being a sweep from +35°C to -5°C and the latter being a sweep from +5°C to -35°C. The performance in terms of electrical energy output and power produced is examined in detail for each group of materials.
