      abstract     = {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.
