Perovskite Oxide For Solid Oxide Fuel Cells

The continuing development of fuel cells offers promising technologies for the conversion of chemical energy from hydrocarbon fuels into electricity without forming air pollutants. Perovskite Oxides for Solid Oxide Fuel Cells provides insight into the materials aspects of one of the most promising fuel cell types available. Solid Oxide Fuel Cells (SOFCs) have significant advantages over other fuel cell types, such as high efficiency, flexibility in fuel, high reliability, simple balance of plant (BOP) and a long history. Because of these advantages, SOFC technology is attracting a great deal of attention for use in power generation and for its potential in heat generation. Perovskite oxides are widely used for different SOFC components. Detailed description of various aspects of perovskite oxides are presented in this book.

This book summarizes the current state of the know-how in the field of perovskite materials: synthesis, characterization, properties, and applications. The book is an essential source of reference for scientists with research fields in energy, physics, chemistry and materials.

This book reports a study of a class of Dion–Jacobson-type layered perovskite oxides in which high oxide-ion conductivities in phases were discovered for the first time in the world. The oxide-ion conductors are important in various energy conversion devices and environmental protection applications such as solid-oxide fuel cells, oxygen gas sensors, oxygen separation membranes, and oxygen-based catalysts. The discoveries are based on a new screening method, called the bond valence method, combined with an original design concept. The present finding of high oxide-ion conductivity reported in the thesis suggested the potential of Dion–Jacobson phases as a platform to identify superior oxide-ion conductors.
