My name is Mónica Chivite Lacaba and I work in the group Preparation, Characterization and Properties of Non-Molecular Solids as a Research Staff (PLI) in the Department of Inorganic Chemistry of the Faculty of Chemical Sciences of the Complutense University of Madrid. My research focuses on the development of families of metal oxides by "Fast and Soft Chemistry" methods with mixed valence and good mixed ionic and electronic conductors (MIEC), with application in intermediate temperature solid oxide fuel cells (IT-SOFC) using hydrogen as fuel. The study of these materials is carried out using techniques such as XRD and NPD for their structural characterisation, while for the study of their properties as electrodes, measurements
