Study on electrode of solid electrolyte hydrogen (isotope) sensor for application to liquid blankets

摘要

The control of hydrogen isotopes is one of the key issues for liquid blankets. For this purpose, monitoring of hydrogen isotopes using on-line sensors is the essential technology. In the present study, the hydrogen sensor using solid electrolyte ceramics was developed for fusion blanket application. Because of very corrosive environment of liquid breeders, Pd membrane electrodes, which will be more protective of the ceramics relative to the conventional porous Pt electrodes, were fabricated and tested. The Pd membrane electrode was shown to perform well in gaseous environment
