A High Functional Cathode Material: Formula for Low-Temperature Solid Oxide Fuel Cells

Abstract

A novel type of (LNF) perovskite oxide, specifically (LNF-46), was synthesized and studied as the cathode for low-temperature, 400–500°C, solid oxide fuel cells (LTSOFCs). The maximum power density of was obtained at 450°C and a rather close result was also obtained at 400°C. The cell performance showed that with a proper choice of the LNF-based cathode material and a suitable electrolyte, the operation of LTSOFC at temperatures 400–500°C is a realistic goal.
