Performance of SrCeO<sub>3</sub>-Type Hydrogen and Steam Sensors Using AlPO<sub>4</sub>・xH<sub>2</sub>O as a Solid Standard

Abstract

Galvanic cell type high temperature steam andlor hydrogen sensors were constructed using SrCeO05YbOg503-q ceramic as a solid electrolyte and AIPO4xH20-LaCoO3mixture as a solid standard materiaL These sensors showed stable and reproducible es corresponding to partialpressureofsteamandhydrogenTherelationbetweeneandlogarithmofsteamor hydrogen was linear 1 1NTRODUCTlON
