Our results reveal a mechanism for permanent degradation of solid oxide fuel cells (SOFCs) by which hydrogen sulfide leads to nickel migration and depletion of the anode, thereby compromising electrical conductivity and cell operation. Additionally, we find that this process is accentuated at higher temperatures and causes depletion of near surface nickel, while deeply buried or trapped nickel remains in the anode.
