Lanthanum based electrolytes properties

However, in this fluorine sensor, the base electrolyte is composed of the lanthanum cation with the fluorine anion. In addition, one unusual property is that the sensor can operate even when directly immersed into aqueous solutions at room temperature. The realization of the application is greatly dependent on two facts Lap3 is stable in water and it shows an excellent fluorine conduction even at room temperature. These remarkable characteristics permit the use of Lap3 as a simple and portable sensor and have led to its commercial use on a worldwide scale. 

However, reliable information about dependence of the functional properties of complex nickelates on their chemical composition and structure is still absent, while any straightforward and accelerated design of cathode materials is to be based upon reliable (and independent upon their interaction with electrolyte) characterization of the ability of then-surface sites to catalyze the oxygen reduction as well as of oxygen mobility in the bulk. Several lanthanum-nickel-iron mixed oxides with perovskite structure have demonstrated promising performance as cathodes for IT SOFC with traditional YSZ and GDC electrolytes [111-112]. However, studies of the behavior of electrode materials in contact with ATLS electrolytes or that of ATLS-based composites are veiy scarce [113].
