This article deals with the durability of solid oxide fuel cell (SOFC) cathodes, especially perovskites of the lanthanum–strontium–manganite (LSM) and lanthanum–strontium–cobalt–ferrite (LSCF) types. Both cathode materials were characterized with respect to either the intrinsic degradation behavior depending on, for example, time, temperature, current density, chemical composition, or the influence of the gaseous chromium species that originate from the oxide layer on the metallic interconnects. Results are presented for single-cell tests and stack tests. Additionally, in the sections describing the influence of Cr on cathode degradation, some basic results are presented on the interaction of single oxides or oxide mixtures with chromium-containing atmospheres.
