Chromium poisoning and degradation at LaNi0.6Fe0.4O3 cathode with LaNi0.6Fe0.4O3–Gd0.2Ce0.8O2 functional layer for SOFC under open circuit condition

We fabricate symmetrical cells adopting LaNi 0.6 Fe 0.4 O 3–δ (LNF) cathode with LNF–Gd 0.2 Ce 0.8 O 2 (GDC) functional layer on scandia-stabilized zirconia electrolyte by screen printing. Degradation of cathode performances by Cr poisoning is studied. Specific polarization resistance ( R p ) increa...
