Solid oxide fuel cell (SOFC) technology has received widening interest in the past ten years. The attractive feature of this technology is its clean and efficient generation of electricity from a broad spectrum of practical fuels ranging from natural gas, biofuels to diesel and coal gas. Potential applications for the SOFC cover portable, mobile, and stationary markets. Significant technical progress has been made in SOFC technology in recent years; however, a number of issues, especially material-related issues, need to be resolved before the technology becomes practical. In this respect, research and development in the material science and engineering of the technology plays a key role. This lecture discusses the development of materials for the SOFC and focuses on how selected materials are tailored and engineered to meet requirements for practical applications.
