✦ Synopsis
800 °C, and so the attempt to modify the LSM-based cathode was made by Kenjo and Nishiya [6]. From their study it was concluded that mixing the LSM cathode with YSZ significantly improved the electrochemical performance due to an increase in the effective reaction surface area. Subsequent studies dealt with different cathode microstructures and fabrication methods, as reported before [7][8][9].
Bismuth-based composite cathodes, such as Ag-ESB (Bi 0.8 Er 0.2 O 1.5 ) and Ag-YSB (Bi 0.75 Y 0.25 O 1.5 ) [10,11], exhibited good performance at intermediate temperatures. And in this study, ESB-LBSM composite cathodes for intermediate temperature solid state fuel cells based on the SSZ electrolyte were investigated, and they were fabricated with a two-step fabricating process including screen-printing and ion-impregnating.
