Solid electrolytes are wider and wider used in electrochemical devices. The
y are of peculiar importance to gas sensors, membranes, pumps and fuel cell
s. The study of the conductivity of the thick film fast ion conducting syst
ems (NASICON and BICUVOX) was carried out using ac impedance spectroscopy.
Investigations of changes of electrolytes conductivity with temperature (Ar
rhenius plots) were carried out. Conducted research was confirmed through p
ractical applications of NASICON in thick film NO2 sensor and BICUVOX solid
electrolyte in fuel cell (SOFC). (C) 2001 Elsevier Science Ltd. All rights
