THE EFFECT OF A-SITE STOICHIOMETRY ON LSCF CATHODE PERFORMANCE AND STABILITY
Abstract
Anode-supported solid oxide fuel cells (SOFCs) were prepared and tested identically except for variations in the A-site stoichiometry of the LSCF cathode. A commercial supplier provided lanthanum strontium cobalt ferrite (LSCF) powders that were stoichiometric [La0.6Sr0.4Co0.2Fe0.8O3-δ], A-site deficient [(La0.6Sr0.4)1-xCo0.2Fe0.8O3-δ], and Sr-deficient [La0.6Sr0.4-xCo0.2Fe0.8O3-δ], in which the imposed deficiency (x) was 0.02, 0.05, and 0.1 in the non-stoichiometric cases. Multiple 1,000 hour tests were run using each LSCF cathode composition. The performance and stability of the cells will be discussed.
