N2 - <p>The concept of using highly electronically conducting backbones with subsequent infiltration of electrocatalytic active materials, has recently been used to develop an alternative SOFC design based on a ferritic stainless steel support. The metal-supported SOFC is comprised of porous and highly electronically conducting layers, into which electrocatalytically active materials are infiltrated after sintering.<br/> This paper presents the first results on single cell testing of 25 cm<sup>2</sup> cells with 16 cm<sup>2</sup> active area of a metal-supported SOFC were the anode backbone consists of a composite of Nbdoped SrTiO<sub>3</sub> (STN) and FeCr. Electrochemical characterization and post test SEM analysis have been used to get an insight into the possible degradation mechanisms of this novel electrode infiltrated with Gd-doped CeO<sub>2</sub> and Ni. Accelerated oxidation/corrosion experiments have been conducted to evaluate the microstructural changes occurring in the anode layer during testing. The results indicate that the STN component in the anode seems to have a positive effect on the corrosion stability of the FeCr-particles in the anode layer.</p>
