    Abstract: A thermionic converter is disclosed comprising a single or multiple hot (emitter) and cold (collector) electrodes mounted side-by-side on a single substrate and a static electromagnetic for guiding electrodes from the emitter to the collector. The thermal path between emitter and collector electrodes is interrupted by cuts or trenches, and electrical connections to the electrodes are routed over a meander-like, high thermal resistance pathway cut into the substrate to further reduce thermal loss. In one embodiment, an Avto metal surface texture of nanoscale indents is provided on one or more of the electrodes to lower a work function. A method for fabricating said monolithic thermionic converter is further disclosed.

    Abstract: The present invention provides an AMTEC cell having a more robust power conductance path (conduction, radiation, convection, and latent heat transfer) from the heat input surface of the cell to the working fluid, evaporation surface, and SES. More particularly, one embodiment of the present invention includes collars, post and/or bridges extending between the SES support plate and the heat input surface. In another embodiment, a plurality of channels or conduits extend between the heat input surface and SES support plate. These embodiments simultaneously increase the thermal conductance path between the heat input surface of the cell and the evaporation surface as well as between the heat input surface of the cell and the SES, and enables superheating of the working fluid. Additionally, posts, fins or heat pipes may be provided in the low pressure zone of the cell between members of the SES to simultaneously increase the conductance between the heat input surface of the cell and the evaporation surface, raise the temperature of the SES, through radiation and/or conduction heat transfer, and isothermalize the SES. Furthermore, posts, fins, or heat pipes may extend from the heat input surface of the cell to a location proximate the SES on the high pressure side to simultaneously raise the temperature of the SES through radiation and conduction heat transfer, isothermalize the SES, and superheat the working fluid through convective heat transfer.

    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. The transition piece divides the member into a first cell and a second cell such that each first and second cell has a beta"-alumina solid electrolyte, a first and second porous electrode and a grid. The transition piece conducts electrons from the interior of the tubular member. There is supply means for supplying sodium to the transporting means. Preferably the supply means is a shell which surrounds the tubular member and is operated at a temperature such that the vaporized sodium condenses thereon. Returning means for returning the condensed sodium from the shell to the transporting means provides a continuous supply of liquid sodium to the transporting means. Also, there are first conducting means for conducting electric current from the transition piece which extends through the shell, and second conducting means for conducting electric current to the grid of the first cell which extends through the shell.
