Tokyo, July 3, 2013: A team led by Prof. Masatomo Yashima of Tokyo Institute of Technology (Japan) and Prof. John A. Kilner of Imperial College London (UK) has successfully visualized the oxygen diffusion pathway in an excellent oxide-ion and electronic mixed conductor, layered perovskite-type cobaltite PrBaCo 2O5+δ. The present work demonstrates a new concept in the material design for high oxide-ion conduction and this can lead to the development of new ionic conductors for better solid oxide fuel cells and oxygen concentrators.
