Abstract

Abstract : La0.7 Sr0.3 Fe0.7 Ga0.3 O3− δ (LSFG) was employed as both anode and cathode in La0.8 Sr0.2 Ga0.83 Mg0.17 O3– δ -supported symmetrical solid oxide fuel cells, achieving 489 mW cm −2 at 800 °C with good cell performance stability and acceptable sulfur tolerance. Abstract : In this research, La0.7 Sr0.3 Fe0.7 Ga0.3 O3− δ (LSFG) perovskite oxide was successfully prepared using a microwave-assisted combustion method, and employed as both anode and cathode in symmetrical solid oxide fuel cells. A maximum power density of 489 mW cm −2 was achieved at 800 °C with wet H2 as the fuel and ambient air as the oxidant in a single cell with the configuration LSFG|La0.8 Sr0.2 Ga0.83 Mg0.17 O3− δ |LSFG. Furthermore, the cells demonstrated good stability in H2 and acceptable sulfur tolerance.
