Layered perovskite oxides have ordered A-cations localizing oxygen vacancies, and may potentially improve oxygen ion diffusivity and surface exchange coefficient. The A-site-ordered layered perovskite PrBa 0.5 Sr 0.5 Co 2 O 5+Δ± (PBSC) was evaluated as new cathode material for intermediate temperatur

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-Δ± (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 β’ C. XRD results sho
