An improved electrode deposition technique has been developed for a Alkali Metal Thermal to Electric Converter (AMTEC). The innovative Sodium Modulated Electrode (SME) deposition technique has been developed which selectively deposits the electrode on inactive Na sites and adjacent to active Na sites on the electrolyte surface. This program has demonstrated SME processing feasibility and achieved electrode performance enhancement. Power density was improved by 51 to 56% at 973 K and 19 to 26% at 1073 K at the start of electrode testing. Na+ has been conducted through the beta’’‐alumina solid electrolyte (BASE) during the deposition process. Electrode deposition has been a random process, covering both active and inactive sites on the BASE. This random process did not optimize electrode placement or provide pore openings at the Na active sites to permit Na+ easy access to electrons and a low resistance path for Na atoms to move to the condenser. Both Mo and TiN electrodes were evaluated. It has been demons...
