Fuel cell technology is quite promising for conversion of chemical energy of hydrocarbon fuels into electricity without forming air pollutants. There are several types of fuel cells: polymer electrolyte fuel cell (PEFC), phosphoric acid fuel cell (PAFC), molten carbonate fuel cell (MCFC), solid oxide fuel cell (SOFC), and alkaline fuel cell (AFC). Among these, SOFCs are the most efficient and have various advantages such as flexibility in fuel, high reliability, simple balance of plant (BOP), and a long history. Therefore, SOFC technology is attracting much attention as a power plant and is now close to marketing as a combined heat and power generation system. From the beginning of SOFC development, many perovskite oxides have been used for SOFC components; for example, LaMnO -based oxide for the cathode and 3 LaCrO for the interconnect are the most well known materials for SOFCs. The 3 current SOFCs operate at temperatures higher than 1073 K. However, lowering the operating temperature of SOFCs is an important goal for further SOFC development. Reliability, durability, and stability of the SOFCs could be greatly improved by decreasing their operating temperature. In addition, a lower operating temperature is also beneficial for shortening the startup time and decreasing energy loss from heat radiation. For this purpose, faster oxide ion conductors are required to replace the conventional Y O -stabilized ZrO 2 3 2 electrolyte. A new class of electrolytes such as LaGaO is considered to be 3 highly useful for intermediate-temperature SOFCs.

Ceramic fuel cells, commonly known as solid oxide fuel cells (SOFCs), have been under development for a broad range of electric power generation applications. The most attractive feature of the SOFC is its clean and efficient production of electricity from a variety of fuels. The SOFC has the potential to be manufactured and operated cost-effectively. The widening interest in this technology, thus, arises from the continuing need to develop cleaner and more efficient means of converting energy sources into useful forms. This topical book provides a comprehensive treatise on solid oxide fuel cells and succeeds successfully in filling the gap in the market for a reference book in this field. Directed towards scientists, engineers, and technical managers working with SOFCs as well as ceramic devices based on conducting materials, and in related fields, the book will also be invaluable as a textbook for science and engineering courses.
