We have developed a Co-free solid oxide fuel cell (SOFC) based upon Fe mixed oxides that gives an extraordinary performance in test-cells with H 2 as fuel. As cathode material, the perovskite Sr 0.9 K 0.1 FeO 3-ı (SKFO) has been selected since it has an excellent ionic and electronic conductivity an

SmBaCo 2 O 5+x (SBCO), an oxide with double-perovskite structure, has been developed as a novel cathode material for intermediate-temperature solid-oxide fuel cells (IT-SOFCs). The electrical conductivity of an SBCO sample reaches 815-434 S cm -1 in the temperature range 500-800 • C. XRD results sho
A novel layered perovskite oxide PrBaCuCoO 5+ı (PBCCO) is employed as a potential cathode for intermediate-temperature solid oxide fuel cells (IT-SOFCs). Thermal expansion and electrochemical performance on samarium-doped ceria (SDC) electrolyte are evaluated. The thermal expansion coefficient (TEC)
