Abstract

Fe-doped La0·3Sr0·7TiO3 (LSFT) is synthesized and systematically characterized towards application as an anode material for direct carbon solid oxide fuel cells (DC-SOFCs). The structural, electrical and electrochemical properties of LSFT under the operation conditions of DC-SOFCs have been evaluated. High structural stability, improved ionic conductivity, electrocatalytic activity, and electrochemical performance are demonstrated. Electrolyte-supported DC-SOFC with LSFT anode provides a maximum power density of 292 mW cm−2 at 850 °C, which is comparable to those state-of-the-art Ni-YSZ anode for DC-SOFC. In addition, it shows excellent long-term operational stability (over 110 h) in H2S-containing CO atmosphere. It thus promises as a novel anode candidate for DC-SOFCs with whole-solid-state configuration.
