Evaluation of High-Temperature Hydrogen Sensors Based on BaCe0.6Zr0.3Y0.1O3-α and Sr(Ce0.9Zr0.1)0.95Yb0.05O3-α Perovskites for Industrial Applications

“…The obtained results were compared with other hydrogen sensors reported in the literature with similar conditions [ 38 , 39 ]. Table 3 shows the analytical parameters of the hydrogen sensors presented in this work and others found in the literature.…”

Comparative Study of Two Different TiO2 Film Sensors on Response to H2 under UV Light and Room Temperature

“…As for sensors for H 2 detection, several studies have also been reported including methods based on catalytic, thermal conductivity, electrochemical, resistance, work function, mechanical, and optical and acoustic [ 37 , 38 , 39 ]. In recent years, solid electrolytes with proton conductivity [ 40 ] have attracted increasing attention of electrochemical devices developers. These materials can be implemented in different medium- and high-temperature electrochemical devices, including fuel cells, electrolysis cells for hydrogen production and hydrogen sensors [ 41 , 42 ].…”

Textured BaCe0.5Zr0.3Ln0.2O3− (Ln = Yb, Y, Gd, Sm, Nd and La) ceramics obtained by the aid of solid-state reactive sintering method

“…High-temperature proton-conducting materials are proposed for applications in electrochemical devices, including solid oxide fuel cells (SOFCs) [1], electrolyzers [2], sensors [3], hydrogenpermeable membranes for hydrogen production [4] or ammonia synthesis [5]. Two representatives of high-temperature protonconducting materials based on BaCeO 3 and BaZrO 3 have been widely investigated in order to be utilized in electrochemical devices operating in real conditions.…”

“…Two representatives of high-temperature protonconducting materials based on BaCeO 3 and BaZrO 3 have been widely investigated in order to be utilized in electrochemical devices operating in real conditions. Because of: (i) the low chemical stability of BaCeO 3 -based system against to H 2 O, CO 2 and other gaseous components [1] and (ii) the difficulties in the densification of BaZrO 3 -based system for obtaining acceptably dense and highly ionic conducting ceramic materials [6], the recent activities have been focused on the development of mixed BaCeO 3 -BaZrO 3 systems, that combine the advantages of both phases [7][8][9].…”
