Development of Ce/ La0.25Sr0.75Cr0.5Mn0.5O3 Anode Catalyst for Further Application in Solid Oxide Fuel Cell Typed Reactor

W. Appamana
Abstract—La0.25Sr0.75Cr0.5Mn0.5O3 (LSCM) and Ce/LSCM were synthesized and investigated for their potential use in an oxidative coupling of methane (OCM) reaction. The catalysts was characterized using XRD, SEM and Impedance. The catalytic activity of catalysts for OCM reaction was both studied in fixed bed and SOFC reactor. A YSZ was used as a solid electrolyte and La0.8Sr0.2FeO3 (LSF) was used as a cathode material. The cell obtained a maximum power density of 221 mW cm-2 in humidified methane. The cell was put under a bias voltage of 0.3 V, which C2 hydrocarbon was generated from the cell. At the highest methane conversion rate, the cell achieved a good C2 hydrocarbon selectivity of 78.4% and a C2 yield of 3.4% at 850 oC.

Index Terms—SOFC reactor, cogeneration, C2 hydrocarbon, LSCM.
