The study explores the integration of bimetallic combinations of transition metals, specifically nickel (Ni), cobalt (Co), and iron (Fe), infiltrated alongside gadolinium doped ceria (CGO) into a strontium titanate backbone to enhance the performance of solid oxide fuel cell anodes. This research employs electrochemical impedance spectroscopy (EIS) to analyze the infiltrated cells across a temperature range of 650° to 850°C and in various atmospheres, including 4% H2O/H2, 50% H2O/H2, 80% H2O/H2, and 50% CO2/CO. In addition, in situ synchronous Raman spectroscopy was performed to further investigate the coking tolerance of the bimetallic infiltrations. The results indicate that the electrocatalytic activity of the bimetallic combinations was analogous to that of single metals, demonstrating electrode area specific resistances of 0.35 Ωcm2, 0.28 Ωcm2, and 1.32 Ωcm2 for Co-Fe-CGO, Ni-Co-CGO, and Ni-Fe-CGO infiltrated cells respectively. Furthermore, the improved coking resistance observed under carbon-rich conditions suggests the potential of Ni-Co-CGO infiltrated cells as optimal candidates for further development as anodes in solid oxide fuel cells.
