Abstract : INVESTIGATIONS WERE MADE OF THE ENERGY CONVERSION MECHANISM IN THERMALLY ACTIVATED CERAMIC-METAL CELLS. Research was focused upon the Fe anode, Li borosilicate enamel-electrolyte and Ag cathode cell configuration. The cell operation temperature range was 450 to 700 C with 600 C being the most satisfactory. The Ag cathode functioned as a gas electrode which absorbed O. The enamel's ionic conductivity increased with temperature and transferred O(--) from the cathode to the anode. Electric power generation resulted from the free energy of anode oxidation reaction. Chemical analyses of discharged cells indicated Li migrated in the electrolyte to the cell cathode. Recharging of cells was not successful due to the iron oxide stability; however, anomalous charge storage was noted at 450 C. Cells made of more reactive anode materials were studied.
