Disclosed is an insulating bonding part for bonding to a solid electrolyte including beta-alumina, the insulating bonding part comprising a plurality of layers which have different mixing ratios of the alpha-alumina and CaO, wherein the layer closer to the solid electrolyte including the beta-alumina has a higher ratio of the CaO, and wherein the layer farther from the solid electrolyte including the beta-alumina has a higher ratio of the alpha-alumina.

Disclosed is an internal current collection structure of a tubular thermal to electric converting cell including an internal electrode, a solid electrolyte and an external electrode. The internal current collection structure includes: a first current collector which closely contacts with the internal electrode of the tubular thermal to electric converting cell; a second current collector which fixes the first porous current collector to the inside of the tubular thermal to electric converting cell and causes the first current collector to be in close contact with the internal electrode; and a lead wire which is a conductive medium and is located between the first current collector and the second current collector.

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.

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.

AMTEC cell and method for manufacturing the AMTEC cell

Disclosed is a material for an electrode having an excellent performance and an excellent durability by maintaining high electrical conductivity and by restraining the growth of the grain at a high temperature. The material can be manufactured by synthesizing composite materials through use of a metallic material of Mo and a ceramic material, and then the composite materials can be used as the electrode.
