Fabrication of Oxide Thermoelectric Generator Element

摘要: A prototype oxide thermoelectric element has been fabricated for the first time, application of power generation at high temperatures in air. Sintered bodies Li0.025Ni0.975O(p-type) and Ba0.4Sr0.6PbO3 (n-type) were directly joined under uniaxial pressure 4 MPa 1123 K 10 h The properties this coupled measured temperature range 440 to 1060 K. This was stable showed no appreciable contact resistance junction after a thermal cycle over 1000 output efficiency calculated be 14 mW 0.64%, respectively, on assumption that hot cold sides 500 K, respectively.
