Enhanced Electrochemical Activity and Chromium Tolerance of the Nucleation-Agent-Free La2Ni0.9Fe0.1O4+δ Cathode by Gd0.1Ce0.9O1.95 Incorporation
For the sake of improving the electrochemical activity and chromium tolerance of the K 2 NiF 4 -type oxide, La 2 NiO 4+δ (LNO), with nonnucleation agents like Mn and Sr elements, the electrochemical performance and degradation were comparatively studied at two cathodes La 2 Ni 0.9 Fe 0.1 O 4+δ (LNF)...

LNF-GDC shows greatly reduced interfacial polarization resistances (Rp), which are only half of those of LNF, indicating a better electrochemical performance. More importantly, no significant degradation of LNF-GDC in performance has been observed under exposure of Cr-containing atmosphere at 700 °C for 350 h, while Rp of LNF increased by nearly 20%, suggesting LNF by GDC incorporation can enhance the electrochemical performance as well as chromium tolerance for intermediate temperature solid oxide fuel cells (IT-SOFCs). |
