Jointing technique and power generation characteristics of p-NaCo2O4/n-ZnO oxide thermoelectric modules

Year: 2007

Type: article

Abstract: A prototype of oxide thermoelectric module consisting of p-NaCo 2 04/n-ZnO sintered materials was successfully fabricated for electrical power generation by applying a diffusion welding technique without filler metals.The power generation characteristics examined in the high temperature region revealed that the diffusion welding technique under a condition of 16 MPa at 1023 Kin Ar was suitable to joint the sintered oxide materials with silver conducting strips.Twelve pairs of pand n-oxides were connected in series with a planar arrangement in a square area of 30x30 mm 2 • A maximum power output of 58 mW was obtained at a temperature condition of THITL = 839/377 K, and no deterioration in power output was observed even after twenty times of heat cycling.
