Applications of metallic films on sodium beta-alumina solid electrolyte (BASE) ceramic in technology for the alkali metal thermal to electric converter (AMTEC) include both electrode and metallization functions.
The experimental techniques developed, as well as the transport properties of some of the films and filled templates, will be presented.

AMTEC cells are under development as power resources for future outer planetary robotic space missions, where they must operate for very long times.
AMTEC, the Alkali Metal Thermal to Electric Converter, is a direct thermal to electric energy conversion device; it has been demostrated to perform at high power densities, with open circuit voltages in single electrochemical cells up to 1.6 V and current desities up to 2.0 A/cm(sup 2).
Miniaturized thermoelectric devices integrated into thermal management packages and low power, high voltage, electrical power source systems are of interest for a variety of space and terrestrial applications.
This paper reports several slow reversible and quasi-reversible processes which occur in the porous electrode/solid electrolyte combination at AMTEC operating temperatures.

A miniature electronic nose in which the sensing media are insulating polymers loaded with carbon black as a conductive medium has been designed and built at the Jet Propulsion Laboratory.
The results of several experiments in which TiN electrodes have been studied at 1120-1200 K are described here.
The lifetime of three types of AMTEC electrodes is predicted from the rate of grain growth in the electrode.
