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
