Performance Comparison of LSCM Anode Materials Prepared by Solid Method and Glycine Nitrate Process
摘要
Abstract
Anode material La0.7Sr0.3Cr0.5Mn0.5 O3-δwas prepared by solid method (LSCM-S) and glycine nitrate process (GNP) (LSCM-G) respectively. Scanning electron microscopy (SEM) showed that the grain size of LSCM-G is smaller than LSCM-S, and the relative surface area was 13.87 cm2/g (LSCM-S) and 24.41 cm2/g (LSCM-G), respectively. The electrical conductivity of LSCM-S was a little higher than LSCM-G in air between 250℃ to 850℃ attributed to the higher electrical activation energy of LSCM-G. While the electrical conductivity of LSCM-G (0.9S/cm) is higher than LSCM-S (0.2S/cm) at 850℃ in CH4, and their electrical conduc-tivity in H2 was almost the same at 850℃ about 0.2S/cm. Temperature process reduction in H2(H2-TPR) showed reaction between LSCM-G and H2 appeared at lower temperature around 500℃ than LSCM-S. In general, LSCM-G material is more wonderful than LSCM-S for intermediate temperature solid oxide fuel cell anode (IT-SOFC).关键词
