摘要
The present invention provides an ionic and electronic insulator interposed between a BASE tube and a tube mounting member in an AMTEC cell for preventing shunt currents from forming between BASE tube electrodes. In a first embodiment of the invention, an insulator is formed integral with the BASE tube by leaching out an alkali metal ion component of the BASE tube at a desired location. In a second embodiment of the present invention, an alpha alumina ring is brazed to the end of the BASE tube. In a third embodiment of the present invention, a glass material seal is formed between the BASE tube and the mounting member.
