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.
This paper presents the first results on single cell testing of 25 cm2 cells with 16 cm2 active area of a metal-supported SOFC were the anode backbone consists of a composite of Nbdoped SrTiO3 (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 CeO2 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.
