Abstract
Biomass derived liquid fuels, bio-oil and biofuels, are attractive as a mix of future energy supply, and its combination with solid oxide fuel cells (SOFCs) would substantially enhance the energy conversion efficiency as compared to the conventional direct combustion. Here we present the preliminary results on the performance and operation stability of tubular \SOFCs\ with conventional Ni-yttria-stabilized zirconia (Ni-YSZ) cermet anode and (La,Sr)MnO3-YSZ (LSM-YSZ) composite cathode running on mallee wood derived bio-oil and biofuels for the electricity generation. The tubular \SOFCs\ show high performance for liquid bio-oil and biofuels, achieving a peak power density ~600 mW cm-2 at 800
