1. A modularized AMTEC cell comprising: a cylindrical base tube including a continuous internal electrode serving as a metal support, the base tube having a concave closed end formed by the internal electrode and an open end;an internal electrode lead penetrating through the closed end of the base tube;a housing supporting the base tube;a joiner, which is located between the base tube and the housing, including an insulating portion and a sealing portion, the insulating portion having a recess formed in a portion of the joiner, the recess being formed to be joined with a lower portion of the internal electrode of the base tube, and the sealing portion being formed to seal the base tube in which the lower portions of the internal electrode and a solid electrolyte are inserted into the joiner, the solid electrolyte being formed on an outer surface of the internal electrode; andan external electrode being formed on an outer surface of the solid electrolyte, and an external electrode lead wire being formed on the external electrode. 2. The modularized AMTEC cell of claim 1, wherein the joiner includes two ends having an opening at both ends allowing gas to pass therethrough, the joiner comprising a cylindrical shape with an empty interior. 3. The modularized AMTEC cell of claim 2, wherein the sealing portion is provided to seal the base tube in such a manner as not to allow gas to pass therethrough, and the insulating portion is joined with the base tube. 4. The modularized AMTEC cell of claim 1, wherein the insulating portion comprises at least one of alpha alumina, anodizing metal and enamel coated metal, and wherein the insulating portion is provided to insulate the base tube from the housing such that the base tube and the housing are not electrically connected to each other. 5. The modularized AMTEC cell of claim 3, wherein the sealing portion comprises at least one of a carbon ring, a gold ring, a silver ring, and a brazing filler. 6. The modularized AMTEC cell of claim 3, wherein the insulating portion of the joiner is joined with the housing by using at least one of welding, O-ring and brazing. 7. The modularized AMTEC cell of claim 1, wherein the internal electrode comprises at least one of molybdenum, titanium, tungsten, copper, nickel, nickel-iron alloy, stainless steel, iron and bronze. 8. The modularized AMTEC cell of claim 1, wherein the solid electrolyte is formed of at least one of a beta-alumina based solid electrolyte and a Na super-ionic conductor (NASICON) based solid electrolyte. 9. The modularized AMTEC cell of claim 1, wherein a material of the external electrode comprises at least one of molybdenum, nickel, aluminum, PtW, RhW, TiC, TiN, SiN, RuO, Ru2O and Rh2W. 10. An AMTEC power generator comprising a plurality of the modularized AMTEC cells of claim 1.
