ABSTRACT:
The present invention provides an alkali metal thermal to electric conversion (AMTEC) cell of the type employing an alkali metal flowing between a high-pressure zone and low-pressure zone in the cell through a solid electrolyte structure. The cell preferably includes a condenser communicating with the low-pressure zone for condensing alkali metal vapor migrating through the low-pressure zone from the solid electrolyte structure. An artery is coupled to the condenser for directing condensed alkali metal from the condenser toward a hot end of the cell. An evaporator for evaporating the condensed alkali metal is coupled to the artery and communicates with the high-pressure zone. A heat shield is disposed in the low pressure zone of the cell for reducing the radiative heat transfer between the hot end of the cell and the cold end of the cell. The heat shield preferably includes a first end having a known area transitioning to a second end encompassing a smaller area than the first end.
