Prof. Kilner is B.C.H.Steele Professor of Energy materials, former head of the Department of Materials and former Dean of the Royal School of Mines. He has been involved in research into ionic and mixed conducting ceramics for 30 years and has published over 350 papers in this and related fields of materials science. He is currently European Editor for the Journal Solid State Ionics and a councillor for the international Society for Solid state Ionics (ISSI). He is the holder of a number of patents relating to fuel cells and gas separation devices and the co-founder of a successful spinout company CeresPower Ltd. Prof.
Kilner is primarily interested in studying the exchange and diffusion of oxygen in oxide ceramic materials for applications in devices such as fuel cells, oxygen separators and sensors, and has been instrumental in the development of isotopic exchange-SIMS techniques to study these phenomena. Much of his work is now centred upon the development of the Intermediate Temperature Fuel Cell, Solid Oxide Electrolysers and Lithium batteries. He is now working on an improved understanding of surface and interfacial phenomena, which is crucial for further development of these devices. In 2012 John was awarded the IOM3 Platinum medal for his outstanding services to the discipline.
