摘要:
Disclosed is a modularized AMTEC cell which does not require a separate collector by using a metal support as an internal electrode, has durability and stability even at a high temperature and a high pressure, very easily joins the cell to a housing by inserting the cell into an insulating portion and sealing, minimizes the number of the parts and expands easily the system scale through the serial-parallel structure.

A liquid transport device includes a channel, a substrate, and a light radiation unit. A liquid containing ions is transported through the channel. The substrate is disposed at a position where the substrate is in contact with the liquid. The light radiation unit radiates light toward the substrate. In the liquid transport device, an asymmetrical temperature distribution in a direction in which the liquid is transported is produced on a surface of the substrate by the light radiated by the light radiation unit.

Disclosed are an open internal electrode AMTEC unit cell, a method for manufacturing the same and a method for connecting circuits. In order to overcome the difficulty in collecting electricity within a conventional AMTEC unit cell, an internal electrode of which a portion is open to the outside, so that the internal electrode and an external electrode can be electrically connected to each other at the outside of the unit cell, and a metal support is used as the internal electrode, so that the internal electrode has durability and stability, and a solid electrolyte is formed in the form of a thin film, and as a result, the AMTEC unit cell has an improved efficiency and a simpler manufacturing process.

The apparatus is a combined Alkali Metal Thermal to Electric Converter (AMTEC) and a thermionic energy converter which are mated by the use of a common heat transfer device which can be a heat pipe, pumped fluid or a simple heat conduction path. By adjusting the heat output surface area of the thermionic converter and the heat input surface area of the AMTEC, the heat transfer device accomplishes not only the transfer of heat from the output of the thermionic converter to the input of the AMTEC, but also the transformation of the heat density to match the requirements of the AMTEC input. The electrical current through the combined devices is also matched by adjusting the heated surface area of the AMTEC.
摘要:
A method is disclosed for bonding nitride and oxide film electrodes on ceramic substrates, which can be used in thermo electric generators. Hydride powders in suspension are coated on a substrate, and heated to selected temperatures for selected periods of times in alternating atmospheres of hydrogen and nitrogen, or oxygen. The method produces satisfactory film electrodes, including electrodes which are greater than 10 microns in thickness.
摘要:
A thermal power transfer system using a phase change liquid gas fluid in a closed loop configuration has a heat exchanger member connected to a gas conduit for inputting thermal energy into the fluid. The pressure in the gas conduit is higher than a liquid conduit that is connected to a heat exchanger member for outputting thermal energy. A solid electrolyte member acts as a barrier between the gas conduit and the liquid conduit adjacent a solid electrolyte member. The solid electrolyte member has the capacity of transmitting ions of a fluid through the electrolyte member. The ions can be recombined with electrons with the assistance of a porous electrode. An electrical field is applied across the solid electrolyte member to force the ions of the fluid from a lower pressure liquid conduit to the higher pressure gas conduit.

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.
摘要:
A thermoelectrochemical system in which a continuous electrical current is generated from a heat input below about 250.degree. C. A hydrogen ion reacting cathode is immersed in a chosen Bronsted acid and a hydrogen ion reacting anode is immersed in a chosen Bronsted base. Reactants consumed at the electrodes during the electrochemical reaction are directly regenerated thermally below about 250.degree. C. and recycled to the electrodes to provide continuous operation of the system.
