| 520 | _ | _ | |a Due to their high operating temperature (700-1000 ̊C), solid oxide fuel cells (SOFCs) are in principle able to work with various types of hydrocarbon fuels, such as natural gas, reformed coal gas (syngas) and biofuels, without high cost catalysts or external reformer. Furthermore, SOFCs have high converting efficiency and environmental compatibility. Because of these attractive features, SOFCs are expected to take over a major role in energy converting technologies in near future. However, for the direct use of commercial hydro carbon fuels in SOFCs, there are several technical challenges still remaining such as sulfur poisoning and carbon deposition on anode surface. Currently, Ni/yttria-stabilized zirconia (YSZ) cermet is typically used as an SOFC anode material [1]. Although Ni shows good catalytic activity for reformation and oxidation of hydrocarbon fuels, the carbon deposition and sulfur poisoning on Ni surface remarkably degrades the electrochemical performance. Therefore, in this study, SOFC with alternative anode materials to prevent sulfur poisoning and carbon deposition were manufactured. This work is finanzed by the Deutsche Forschungsgemeinschaft (DFG), a collaborative work of Jülich research center (JÜLICH) and Technical University of Munich (TUM) and is aiming for the coupling of a biomass gasification system and an SOFC. The new cells were manufactured by JÜLICH, and the cells have been tested at TUM. As an alternative anode, Ni/gadolinia-doped-ceria (GDC) anode is attempted instead of Ni/YSZ. It is reported that the GDC has better poisoning resistivity and higher conductivity than YSZ [2-3]. A third way is to modify the Ni/YSZ anode with molybdenum which is well known as excellent desulfurization material [4]. To compare the new anode cell with state-of-the-art cell, all cells are also manufactured by tape casting and screen printing according to procedures established in JÜLICH [5]. At TUM, reference cells are tested with various kinds of tar containing fuels to clarify the poisoning mechanism. After cell test, post-test analysis of microstructure and phase transformation was performed in JÜLICH. The poster summarizes the results obtained so far.References: [1]. M. Ihara, T. Kusano, and C.
