Paper Abstract

The purpose of this work was to investigate the performance and working mechanism of potentiometric hydrogen sensors, based on proton-conducting oxide solid electrolytes. The SrCe1-xYxO3-y compounds (0≤×≤0.2) were prepared by solid-state reaction method; different concentrations of yttrium dopant (x) were used. The measurements of Open Cell Voltage (OCV) of constructed cells-sensors as a function of gas concentration and temperature were performed. Studied sensors exhibited short response and recovery times and satisfactory repeatability of the sensor signal. The discussion of the working mechanism within the frame of defect structure and transport properties of proton-conducting solid electrolyte was also presented in this work.
