Abstract
In this paper, a material Sr2Fe1.4Mn0.1Mo0.5O6-δ(SFMn0.1M) was synthesized by a sol-gel combustion method and taken as anode materials for intermediate temperature solid oxide fuel cells (IT-SOFCs). The crystal structure, microstructure, element valence, conductivity and electrochemical properties of SFMn0.1M were characterized. The results of X-ray diffraction (XRD)show that, Mn-doped SFMn0.1M still possesses pure perovskite crystal structure and the 3D interconnected network microstructure composed of nano-particles. The results of electron microscope (SEM) scanning reveal the interconnected porous structure of SFMn0.1M. In addition, SFMn0. 1M exhibits excellent electrochemical performance with the highest conductivity of 14.7 S•cm-1 at 800℃; and the peak power densities of single cells based on the SFMn0.1M anode can reach 565.2, 385.2, 303.9 and 141.2 mW•cm-2 at 800, 750, 700 and 650℃, respectively. All these results show that SFMn0. 1M material is a promising anode for IT-SOFCs.
