Solid Oxide Fuel Cells (SOFC) have attracted increased attention due to their potential to lower operating temperatures, which is crucial for advancing the widespread application of SOFCs. Since the power output of a SOFC is closely related to the electrochemical performance of the electrodes, nanostructuration of the anode increases the surface-to- volume ratio of the three boundary conditions where the reactions take place. In this work, the preparation and characterization of nanostructured anodes based on NiO-GDC nanowires (NWs) are proposed. Synthesized by Vapor-Liquid-Solid growth technique, the NWs have been systematically investigated by scanning electron microscope (SEM), X-ray diffraction (XRD), and Raman spectroscopy. Functional characterization of the power output fuel cell performance together with Electrochemical Impedance Spectroscopy analysis were carried out at different temperatures and for different oxygen and hydrogen fuel flows.

Abstract
Solid Oxide Fuel Cells (SOFC) have attracted increased attention due to their potential to lower operating temperatures, which is crucial for advancing the widespread application of SOFCs. Since the power output of a SOFC is closely related to the electrochemical performance of the electrodes, nanostructuration of the anode increases the surface-to- volume ratio of the three boundary conditions where the reactions take place. In this work, the preparation and characterization of nanostructured anodes based on NiO-GDC nanowires (NWs) are proposed. Synthesized by Vapor-Liquid-Solid growth technique, the NWs have been systematically investigated by scanning electron microscope (SEM), X-ray diffraction (XRD), and Raman spectroscopy. Functional characterization of the power output fuel cell performance together with Electrochemical Impedance Spectroscopy analysis were carried out at different temperatures and for different oxygen and hydrogen fuel flows.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
