Abstract

Ruddlesden?Popper type oxide, La0.5Sr1.5MnO4+?, is investigated as a potential electrode material for symmetrical solid oxide fuel cells. This work improves its electrochemical catalytic activity through over doping nickel to form a B-site excess oxide, (La0.5Sr1.5Mn)Ni0.1O4+?. X-ray diffractometry shows that the over doped oxide has the Ruddlesden?Popper structure when heated up to 800
