Ni0.75Fe0.25 Coated Tubular GDC Anode for Cathode-Supported IT-SOFC with High Anode Porosity

Abstract

Ni0.75Fe0.25Ox-GDC cermet anode for intermediate temperature solid oxide fuel cell was prepared by hard template method and wet impregnation method. LSC-GDC cathode-supported single cell was fabricated by using Ni0.75Fe0.25 coated tubular GDC as anode for the performance test. The composite anode material with Ni-Fe alloy particles coated tubular GDC was analyzed by XRD and SEM. The maximum power density of the single cell in hydrogen and dry methane was 736 and 400 mW·cm-2 at 800 °C, respectively. The SEM observation showed that the anode had a porous three-dimensional microstructure with high specific surface and rich gas channel, resulting a high power generation performance.
