Stacked Vapor Fed Amtec Modules
US Patent:
4808240, Feb 28, 1989
Filed:
Sep 8, 1987
Appl. No.:
7/095384
Inventors:
Robert K. Sievers - North Huntingdon PA
Assignee:
The United States of America as represented by the United States
Department of Energy - Washington DC
Department of Energy - Washington DC
International Classification:
H01L 3700
US Classification:
136202
Abstract:
The present invention pertains to a stacked AMTEC module. The invention includes a tubular member which has an interior. The member is comprised of a ion conductor that substantially conducts ions relative to electrons, preferably a beta"-alumina solid electrolyte, positioned about the interior. A porous electrode for conducting electrons and allowing sodium ions to pass therethrough, and wherein electrons and sodium ions recombine to form sodium is positioned about the beta"-alumina solid electrolyte. The electrode is operated at a temperature and a pressure that allows the recombined sodium to vaporize. Additionally, an outer current collector grid for distributing electrons throughout the porous electrode is positioned about and contacts the porous electrode. Also included in the invention is transporting means for transporting liquid sodium to the beta"-alumina solid electrolyte of the tubular member. A transition piece is positioned about the interior of the member and contacts the transporting means.
High Voltage Alkali Metal Thermal Electric Conversion Device
US Patent:
5228922, Jul 20, 1993
Filed:
Feb 19, 1991
Appl. No.:
7/656530
Inventors:
Robert K. Sievers - Irwin PA
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
H01L 3700
US Classification:
136202
Abstract:
A high voltage multitube alkali metal thermal electric convertor having a plurality of closely packed tubular cells disposed in a tube sheet in a vessel and electrically connected in series, the tube sheet dividing the vessel into a high pressure high temperature portion having a wick and heater disposed therein and a low pressure low temperature portion having a wick disposed in a condenser from which heat is removed; a pump for transferring liquid metal therebetween and a tab on a wick disposed in the tubular cell to remove excess liquid metal and prevent shorting between the cells.
High Performance Thin Film Alkali Metal Thermoelectric Device
US Patent:
5039351, Aug 13, 1991
Filed:
Jan 22, 1991
Appl. No.:
7/644404
Inventors:
Martin H. Cooper - Churchill Boro PA
Robert K. Sievers - Irwin PA
Robert K. Sievers - Irwin PA
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
H01L 3700, H01M 636
US Classification:
136202
Abstract:
An alkali metal thermoelectric conversion device formed from a porous tube or plate coated with a thin film of beta-alumina, the porous tube or plate is sintered metal or metal alloy having a coefficient of thermal expansion which approaches that of the beta-alumina to form a mechanically stable device with high electrical output.
Flat Plate Alkali Metal Thermoelectric Converter Module
US Patent:
5089054, Feb 18, 1992
Filed:
Nov 28, 1990
Appl. No.:
7/619354
Inventors:
Robert K. Sievers - Irwin PA
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
H01L 3700
US Classification:
136202
Abstract:
A flat plate alkali metal thermoelectric converter module having a plurality of generally flat plate cells grouped in stacks that are electrically connected in series within the stack, the cells being disposed to minimize the heat energy radiated to a condenser to provide a high efficiency module.
