A study of an alkali-metal thermoelectric converter (AMTEC) utilizing the sodium ion-conducting β″-alumina to convert heat energy directly to electric energy is presented. A film electrode is fabricated on the surface of a β″-alumina disk using a magnetron sputtering system with molybdenum target. The electrode-disk combination is tested at 1073 K. An open voltage of 0.99 V and a short-circuit current of 1.82 A/cm2 are obtained. A maximum power density of 3.4 kW/m2 is obtained at a current density of 0.88 A/cm2 and a voltage of 0.38 V. This power density is about 65% of the theoretical value which is calculated assuming an internal resistance equal to the resistance of 2-mm-thick β″-alumina.
