Perovskite-type materials SOFCs anodes

The flexibility of the perovskite crystal structure and the opportunity to accommodate various dopants offer the possibihty to tailor material properties. The design of catalytic or electronic properties, such as ionic or electronic conductivity, is in the focus of solid oxide fuel cell (SOFC) research activities. Perovskite-type oxides are therefore a well-investigated class of materials and commonly applied as functional layers in SOFCs, as porous microstructured cathode layer on the air electrode side [32-36] and very recently as anode on the fuel side [35]. On a research level, perovskite-type oxides are also apphed as gas-tight electrolyte to separate anode and cathode compartments [37,38] or as an interconnector material [39,40]. Beside the stoichiometry and crystal structure, processing...
