Abstract [en]

Double perovskite materials, Sr2CoMoO6 and Sr2NiMoO6, (denoted as SMMO, M=Co, Ni) were synthesized as symmetric electrodes in SOFC fed with H2-H2S. Ce0.85Sm0.15O2-δas intermediated temperature solid electrolytes was adopted to fabricate single cell with structure of SMMO|SDC|SMMO. Electrochemical performances of two types of SOFCs as well as impedance tests were tested. Compatibility between electrodes and electrolytes was characterized by SEM-EDX. Temperatureprogrammed techniques, including H2-TPR, O2-TPD, were used to test catalytic activities of electrodes in different atmosphere, while thermogravimetry analysis was performed to evaluate their sulfur tolerance. Application of symmetric electrodes in SOFC, especially in IT-SOFC, simplifies the manufacture process of SOFC and reduces SOFC costs greatly.
