Abstract: An embodiment provides an alkali metal thermal-to-electric converter including a thermal-to-electric conversion cell including three layers including an anode layer, a solid electrolyte layer, and a cathode layer, having a convex-concave shape with alternately appearing concave and convex portions, and configured to move alkali metal ions through the solid electrolyte layer, a high temperature portion that supplies a high temperature alkali metal fluid to the anode layer of the thermal-to-electric conversion cell, and a low temperature portion that condenses the alkaline metal fluid discharged to the cathode layer of the thermal-to-electric conversion cell to a low temperature and moves the alkaline metal fluid to the high temperature portion.
