Combined Cr and Mo poisoning of (La,Sr)(Co,Fe)O3 − δ solid oxide fuel cell cathodes at the nanoscale
Cr poisoning has been identified as a critical issue for solid oxide fuel cell (SOFC) cathodes degradation when metallic alloys are used for intermediate temperature SOFCs. In addition, Mo is also a common alloying element in ferritic stainless steel or Ni based alloys considered as interconnect materials and molybdenum trioxide is very volatile, raising concerns on Mo poisoning to the cathodes.
