“…Recent similar finding regarding the utilization of oxide-SEs was also reported by Fadeyev et al; the sensors using single-oxide SEs such as ZnO and SnO 2 generated higher H 2 responses, compared with other examined single oxides [155]. The development of YSZ-based sensors aiming at H 2 detection is summarized in Table 4.…”

“…The expensive material cost for the sensor using noble metal SE (including catalyst and current collector) has become one of the motivation for utilization of inexpensive metal oxides as the SE materials [83,[155][156][157]. Recent similar finding regarding the utilization of oxide-SEs was also reported by Fadeyev et al; the sensors using single-oxide SEs such as ZnO and SnO 2 generated higher H 2 responses, compared with other examined single oxides [155].…”

A robust and reliable gas sensing device is considered as a convenient and practical solution for gas concentration monitoring that has become a mandatory requirement in different field of applications. For in situ hazardous gases detection, a mixed-potential type gas sensor has been regarded as a promising solid-state gas sensor. For the past three decades, there has been a significant progress in achieving high performance in mixed-potential type sensors. Therefore, this review is focused on reporting the development of mixedpotential type gas sensors with combined yttria-stabilized zirconia (YSZ) as the base solid electrolyte material and various classes of electrode materials for their potential utilization as a high-performance sensing electrode. The underlying sensing mechanism of a mixed-potential type YSZ-based sensor is elaborated here in detail. Transformation in design and configuration of this type of sensor is also covered in this report. In addition, recent progresses on mixed-potential type gas sensors development for detection of several target gases, such as carbon monoxide, hydrocarbons, nitrogen oxides, hydrogen, and ammonia, are reviewed. Strategies to improve the sensing characteristic, particularly gas sensitivity and selectivity, are also reported. Based on the understanding of the fundamental sensing mechanism and the requirements for high-performance gas sensors, challenges and future trends for this type of gas sensor development are discussed.

“…In terms of the potential-type [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ] and the limiting current-type [ 9 , 10 , 11 , 12 , 13 , 14 ] sensors, the detection principles involve monitoring of the voltage or current that is generated by the difference in oxygen concentration between both ends of the solid electrolyte. However, the voltage or current of the solid electrolyte is also affected by the flammable gases [ 3 , 5 , 6 , 13 ]. The galvanic cell-type, on the other hand, is not affected by the presence of flammable gases [ 15 , 16 ], but unfortunately the sensing response rates of galvanic cell-type sensors are generally too slow for the monitoring processes.…”

We have investigated the catalytic layer in zirconium-doped cerium oxide, Ce0.9Zr0.1O2 (CeZr10) resistive oxygen sensors for reducing the effects of flammable gases, namely hydrogen and carbon monoxide. When the concentration of flammable gases is comparable to that of oxygen, the resistance of CeZr10 is affected by the presence of these gases. We have developed layered thick films, which consist of an oxygen sensor layer (CeZr10), an insulation layer (Al2O3), and a catalytic layer consisting of CeZr10 with 3 wt% added platinum, which was prepared via the screen printing method. The Pt-CeZr10 catalytic layer was found to prevent the detrimental effects of the flammable gases on the resistance of the sensor layer. This effect is due to the catalytic layer promoting the oxidation of hydrogen and carbon monoxide through the consumption of ambient O2 and/or the lattice oxygen atoms of the Pt-CeZr10 catalytic layer.

“…SPE became important during the mid-1970s because of the inefficiencies and maintenance requirements of liquid electrolytes [6]. And it is often used in gas sensors [22][23][24][25], especially for trace gas analysis [26]. In the Nafion-based AGS design, Nafion film is used both as the electrote and as a support for the electrode structure.…”
