【 摘 要 】

tsBulk-heterostructure electrolytes based on Ce0.8Sm0.2O2-δ and SrTiO3 are developed for solid oxide fuel cellsThe interface characteristics are investigated to understand the fast ionic transport obtained in the heterostructure.The Schottky junction effect is proposed by taking account of work functions and electronic affinities for the first time.
