Reevaluating the Cr Evaporation Characteristics of Ce/Co Coatings for Interconnect Applications

Cathode poisoning by chromium evaporation from the interconnects is one of major degradation mechanisms in SOFC. Coatings have proved to be very effective suppressing on interconnects. The quantification important for determining consumption interconnect and predicting lifetime interconnect.
