ISBN The free VitalSource Bookshelf® application allows you to access to your eBooks whenever and wherever you choose. Progress in the development of oxygen ion and mixed conductors is responsible for innovations in the fields of gas sensors, fuel cells, oxygen permeation membranes, oxygen pumps and electrolyzers. Commercialization has been impeded by materials stability and compatibility issues, high costs of. The magnitudes of the oxygen fluxes through ceramic oxides incorporated in a variety of technological devices and systems are briefly surveyed, and attention is drawn to the importance of the kinetics of the associated surface exchange process. For most applications, oxygen ion conductivities greater than 10 −1 S cm −1 are required at intermediate temperatures (– °C).Cited by: Buy [(Ceramic Oxygen Ion Conductors and Their Technological Applications)] [Edited by B.C.H.

A number of perovskite oxides are purely oxide ion conductors and, as such, have been used as electrolytes in the intermediate temperature range (–°C). Of the perovskites investigated to date, only the lanthanum gallate (LaGaO 3) based material has been found to be suitable for ionic by: Oxygen Ion based solid electrolytes because of their suitable applications in SOFCs, oxygen sensors and oxygen pumping devices []. science and technology of ceramic . In all oxygen ion electrolytes of interest (in some mixed ionic conductors, such as La 2 NiO 4 of interest as solid oxide fel cell cathodes, ionic conduction is largely via oxygen interstitials), the interstitial does not appear to make significant contributions to the ionic conductivity, and so it is the product of the oxygen vacancy Cited by: Dense membranes of ceramic oxygen ion conductors are of great interest because of their ability to transmit high oxygen fluxes with total selectivity. These membranes may be solid electrolytes exhibiting negligible electronic conductivity, or mixed ionic-electronic by: 8.

In , the operation of the first ceramic fuel cells was demonstrated for the first time. Mainly ZrO2-based ionic conductors in the form of a tubular crucible as the electrolyte were used, with iron or carbon as the anode and Fe as the cathode. Currently, ceramic fuel cells use exclusively hydrogen as fuel, and oxygen as oxidant. Ceramic ion conducting membranes Brian CH Steele Ceramic ion conducting membranes are a generic group of materials with many potential large-scale applications in solid oxide fuel cells, oxygen generators and partial oxidation reactors. At present the transport and surface exchange kinetic characteristics are emphasized to maximize ionic by: Preface to ”Ceramic Conductors” Ceramic conductors are fabricated throughout the world by both industry and researchers. They are one of the most important types of materials for various technologies, especially those related to energy harvesting. The research on their properties is therefore crucial for the development of modern society. Data for representative conductors are tabulated. A number of applications that rely on solid state electrolytes and/or mixed ionic–electronic conductors are considered, and the criteria used to choose such materials are reviewed. Emphasis is placed on fuel cells, sensors and batteries, where there is strong scientific and technological interest.
