    Direct utilization of hydrocarbon fuel for solid oxide fuel cells (SOFC) is a challenge due to anode poisoning and severe coke formation which may lead to total anode deactivation. Perovskite has been extensively studied as a replacement for the traditional Ni-based anode due to its high tolerance to hydrocarbon fuel as well as its remarkable tailored properties. Due to the complicated nature of direct hydrocarbon oxidation in SOFC, the requirement for a suitable anode is often beyond the capabilities of the current material. Here we examine Al and Co doped La0.5Sr0.5MnO3 (LSMAC), a coke tolerant perovskite which is mixed with either Sr0.94Ti0.9Nb0.1O3 (STN), Ce0.8Gd0.2O2 (GDC), Ce0.6Mn0.3Fe0.1O2 (CMF), La0.6Sr0.4Fe0.9Mn0.1O3 (LSFM) or La0.9Sr0.1Ga0.8Mg0.2O3 (LSGM) to be evaluated as composite anodes for solid oxide fuel cells under direct utilization of dry C3H8 fuel. Whilst LSMAC mixed with STN demonstrated remarkable power density improvement over LSMAC from 533 to 831?mW/cm2 in direct C3H8 fuel at 1173?K, drastic decrease is shown when operating at lower temperature. Instead, we report enhanced electrochemical performance from composite LSMAC-GDC at lower temperature owing to faster kinetic reaction and preserved microstructure under reducing environment.
