The Ninth International Symposium on Solid Oxide Fuel Cells: Materials, Science, and Technology was held in January 2012 as part of the 36th International Conference on Advanced Ceramics and Composites (ICACC). This symposium provided an international forum for scientists, engineers, and technologists from around the world to present and discuss the latest advances in solid oxide fuel cells. This issue features fourteen papers selected from the symposium, offering readers a broad panorama of the current status of solid oxide fuel cells technology, as well as emerging issues and future directions in the field.
