Original Paper


The ability for direct utilization of hydrocarbons had extended commercial applications of solid oxide fuel cells (SOFCs). In this regard, using ceramic materials instead of cermet composite anodes to overcome the carbon deposition and sulfur poisoning is a promising approach which improves stability of the cell in a hydrocarbon atmosphere. In this study, La0.75Sr0.25Cr0.5Mn0.5O3−δ/Zr0.92Y0.08O2-β (LSCM/YSZ) was used as a fully ceramic anode electrode for methanol oxidation reaction. In order to improve the electrode performance, infiltration of LaFe0.6Co0.4O3 (LFC) and LaFe0.58Co0.37Pd0.05O3 (LFCP) solutions onto the LSCM/YSZ composite backbone was investigated. Electrochemical impedance spectroscopy (EIS) was utilized for the characterization of pure and infiltrated cells. The results revealed that LSCM/YSZ has a large electrode polarization resistance for methanol oxidation reaction while introducing LFC nanoparticles onto the microstructure of ceramic anode significantly promoted the electrocatalytic activity of LSCM/YSZ electrode. For instance, electrode polarization resistance for the methanol oxidation reaction decreased significantly (~ 92%) after infiltration of 0.3 M LFC solution at 850 °C. Analyzing the impedance data using an equivalent circuit showed that LFC infiltration mainly enhanced the reaction active sites and impressively promoted the electrode processes at medium and low frequencies. Utilization of LFCP instead of LFC did not cause further enhancement in the performance of the electrode for methanol oxidation reaction.
