Current-Collecting Grids For AMTEC Electrodes

Photodeposition or sputter deposition of refractory metal in grid pattern on solid electrolyte of alkali-metal thermoelectric converter (AMTEC) prior to deposition of electrode decreases electronic resistance and increases current and peak power of converter significantly. Concept also applicable to other devices that include electrically conductive, porous electrodes; such as solid-state fuel cells and solid-state electrolysis cells.
