Title THERMOELECTRIC CONVERSION MATERIAL, AND THERMOELECTRIC CONVERSION DEVICE, THERMOCHEMICAL BATTERY AND THERMOELECTRIC SENSOR HAVING SAID MATERIAL
Abstract Provided are a thermoelectric conversion material having a considerably increased Seebeck coefficient, and a thermoelectric conversion device, a thermochemical battery and a thermoelectric sensor which include the material. The thermoelectric conversion material of the present invention comprises a redox couple and a trapping compound by which only one of the redox couple is selectively trapped at low temperature and released at high temperature.
Outline of related art and contending technology BACKGROUND ART
Such as the waste heat for a very small energy to electric power, the thermoelectric conversion material has attracted attention in recent years. Among them as an energy source to the mobile devices, efficient thermoelectric conversion material having a thin server is expected. Incidentally, the concentration of the compound in the culture medium composition, can be calculated using the following equation. Therefore, reducing oxide thermoelectric conversion material with a solution of ions of a chemical battery is a kind of heat, have garnered much attention in recent years (Non-Patent Document 1).
The conventional solid-state thermoelectric Seebeck coefficient of about 0.2mV/K (Se) alloy and on the other hand, the thermo-chemical battery is the Seebeck coefficient has a value one order of magnitude larger (Se) with, can be manufactured at low cost is expected. For example, I- and I3- heat from the chemical battery, formed by the oxidation-reduction equilibrium equilibrium potential, by being separated at the high and low temperature to generate a potential. About its Seebeck coefficient and 600μV/K, the alloy-based thermoelectric conversion material is high in comparison with the known. However, the lower the conductivity of the electrolyte was a problem. And further necessary to improve the Seebeck coefficient (non-patent document 2) has been.
