Activities are focused on functional materials (metals or ceramics with protonic-anion and mixed conductivity) for fuel cells (SOFC), electrolysis cells (SOEC) and stacks. In addition to the formulation of new materials, a detailed study of the effects of composition, microstructure and degradation phenomena on performance is carried out on state-of-art materials.
The research aims at improving performance of devices by addressing degradation phenomena also through innovative cell designs.
Our approach to the optimization includes careful control of synthesis of materials, the fabrication of optimized composite electrodes and electrolytes by colloidal techniques (spraying, infiltration of porous structures), the investigation of interface phenomena by electrochemical impedance spectroscopy.
Dedicated benches for advanced electrochemical testsing are also developed in collaboration with external experts and with the support of regional projects (POR-FESR-LIGURIA - 2012-2014). The collaboration with other research institutions (Dipartimento di Ingegneria Civile e Industriale (DICI) dell'Università di Pisa, Centre des materiaux, Mines Paris Tech), allows the development of an intense modelling activity for the description of correlations between microstructural features and SOFC/SOEC performance.
Finally, the research on new materials extends to inorganic composites and organic-inorganic hybrids, aiming at reducing the operative temperature of SOFC, especially by using protonic conductors.
About SOFC stacks degradation phenomena studies, particular importance is given to the oxidation of ferritic stainless steels under realistic operating conditions.
The research activity is also carried out in close collaboration with a research group of the University of Genoa through the MErgELab laboratory. The collaboration also extends to DICCISM from University of Pisa.
