000202764 520__ $$aAnode supported Solid Oxide Fuel Cells (ASC) manufactured at Forschungszentrum Jülich have proven excellent electrical efficiency and long term performance when combined of  a Nickel/8 mol% yttria stabilized zirconia (Ni/8YSZ) substrate, a Ni/8YSZ anode, a dense 8YSZ electrolyte membrane, a gadolinia doped ceria (GDC) barrier layer and lanthanum strontium iron cobaltite (LSCF) cathode. However, recently we observed a large scatter of the  electrical performance during stack operation with hydrogen fuel. In this study, we systematically examined this performance variance of planar anode-supported SOFC stacks. In close cooperation with the Karlsruhe Institute of Technology (KIT), anode supported cells were characterized before and after stack operation by SEM-imaging and electrochemical impedance spectroscopy. While a number of factors, including the contacting of the LSCF cathode, the properties of the interconnector protection layers and operational parameters contribute to the performance variation, we were able to identify the microstructure of the GDC barrier layer as the major source for lowered and fluctuating performance. The ability of this barrier layer to inhibit the formation of low conductivity strontium zirconates at the 8YSZ electrolytes surface was revealed to be strongly and asymmetrically dependent on the sintering parameters applied to the GDC layer.
