(La,Ca)MnO 3 doped with either cobalt or nickel on the manganese site has been used as the electrode for NO x sensors [319]. The outputs of some NO x sensors with perovskite electrodes are shown in Figure 13.26 [255,256,264,275,309,312].…”

Solid electrolytes are well suited for use in chemical sensors for high-temperature applications. The first such sensors followed from the use of solid electrolytes for thermodynamic measurements, and are based on galvanic cells, for which the open circuit voltage is related to the concentration of the mobile ionic species, or to another target species through equilibration at the electrode surface. However, sensors can also be based on nonequilibrium, but steady-state, potentials established between electrochemical reactions at the electrode. Another approach is to use the current passing through the electrolyte, rather than the voltage across the electrolyte, as the sensor signal. In this chapter we first describe the different methods for using solid electrolytes in chemical sensors, and then discuss some of the materials challenges and example applications. IntroductionMore than 50 years ago, Kiukkola and Wagner [1] demonstrated that solid electrolytes couldbeusedingalvaniccellstomeasurethethermodynamicpropertiesofoxides.Those pioneering studies subsequently led to the more practical application of solid electrolytes in chemical sensors. The ionic conduction in solid electrolytes is thermally activated and thus its rate increases with increasing temperature; consequently, solid electrolytes are well suited for high-temperature applications. On the other hand, such temperature dependencealsomeansthatsensorsbasedonsolidelectrolytescanrespondsluggishlyor may be inoperable at low temperatures. However, one of the advantages of solid-state devices, such as those based on solid electrolytes, is that they can be miniaturized [2,3].
