A systematic literature review on BSCF-based cathodes for solid oxide fuel cell applications

Academic research into Ba_1-y Sry Co_1-x Fex O ₃ cathode (BSCF) for solid oxide fuel cell (SOFC) applications has proliferated significantly over the last few years. However, the homogeneity of literature data has not been investigated yet. In the present review, a systematic literature screening is conducted. The study is organized into two main categories (geometries and configurations) and various subcategories as a function of performance classification, which was published on the subject. A semi-empirical model is applied to predict the cell performances on two film thickness (electrolyte and cathode) and three cell fabrication variables (cathode synthesis temperature, firing temperature, and cathode particle size). The semi-empirical model of cell performance showed a good agreement with simulated and literature data. It is concluded that a systematic literature reviewing process holds great potential for the understanding of the mechanisms, which regulate BSFC cathode-based SOFC operation, and thus represents a tool of primary importance for any further advance in the field of SOFC.
