Abstract

The fact that NaCl in air has induced degradation of cathode has been investigated for La0.6Sr0.4Co0.2Fe0.8O3 (LSCF). Cell performance was measured by volatilizing NaCl into the air supplied to the cathode at a constant current density of 200 mA cm-2 up to 100 h. At 800 oC, an exposure to 30 ppm NaCl caused negligible degradation of LSCF cathode at least for 100 h, yet degradation became obvious with increasing NaCl concentration. Slight change in the composition of the cathode materials was observed which may lead to the gradual degradation of cell performance. In addition, cell performance degradation was compared between 700 oC to 900 oC, being poisoned by 30 ppm NaCl. The LSCF cathode showed slightly poor tolerance of NaCl at 700 oC due to the decomposition of the cathode material. The long-term influence of NaCl on cathode performance should be done to clarify.
