Investigation of Ni1-xFex synthesized hydrazine reduction method as the anode of Solid Oxide Fuel Cells |
초록 |
We have investigated on YSZ-Ni1-xFex as an anode material of solid oxide fuel cells in order to improve the anodic performance. We synthesized Ni1-xFex via hydrazine reduction method, and then synthesized Ni1-xFex and YSZ were mixed. Structural and electrical analyses of YSZ-Ni1-xFex were performed by using field-emission scanning electron microscope (FE-SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS), respectively. In XRD analysis, we confirmed Fe atoms are well-substitute onto Ni-site because of additional Fe-peaks were not observed. Also, we could observed higher electrical conductivity of Ni-Fe system. Especially, carbon-deposition rate is very important factor in terms of long-term stability of SOFCs under operation, lower carbon-deposition rate of YSZ-Ni0.95Fe0.05 cermet exhibited than YSZ-Ni cermet. Also, anodic performance of Ni1-xFex cermet depending on Fe-contents was explained by XPS analysis. |
