固体電解質(イオン導電体)を用いた液体金属中の酸素,水素の濃度測定及び制御を目的として、プロトン導電体であるSrCe$$_{0.95}$$Yb$$_{0.05}$$O$$_{3-x}$$と酸素イオン導電体であるイットリア安定化ジルコニアの基礎的な電気化学特性(分圧に対する起電力,イオン導電率等)を測定し、イオン導電体を用いた測定デバイスの実現性について検討した。

A solid electrolyte (ionic conductor) cell has been developed for measurement and control of hydrogen and oxygen density in liquid metal blanket with LiPb. The ceramic tubes of the SrCe$$_{0.95}$$Yb$$_{0.05}$$O$$_{3-x}$$ (proton conductor) and Yttria Stabilized Zirconia (oxygen ion conductor) that can be used at operating temperature of LiPb blanket have been utilized for electrolytes of the devices, which enable the continuous measurement of respectively hydrogen and oxygen in liquid LiPb. Fundamental electrochemical data such as EMF for a partial pressure and ion conductivity were measured, and the results were used to evaluate the feasibility of these devices.
