Currently, solid oxide fuel cell (SOFC) anode materials don't support the use of complex hydrocarbon fuels that can lead to eventual device failure from unwanted graphitic and metal sulfide formations. These limitations have spurred the investigation of new mixed ionic and electronic conducting (MIEC) materials that are effective at blocking these formations. The MIEC anode material used in this study was the double perovskite, Sr2MgMoO6. X-ray absorption spectroscopy (XAS) was used in conjunction with a unique, electrochemical assembly to allow for the non-invasive exploration of these materials during operation at 800�C. When observing the Mo K-edge at 800�C, its evident that Mo was multivalent and also responsible for creating oxide vacancies throughout the crystal structure. This revealed that Mo plays a large role in the electronic and ionic conduction of this material. This work was completed at the 10-ID Beamline located at the Advance Photon Source at Argonne National Laboratory.
