Hierarchically nanoporous La 1.7 Ca 0.3 CuO 4−δ and La 1.7 Ca 0.3 Ni x Cu 1−x O 4−δ (0.25 ≤ x ≤ 0.75) as potential cathode materials for IT-SOFCs

Hierarchically nanoporous La 1.7 Ca 0.3 Ni x Cu 1−x O 4−δ layered perovskite oxides prepared by a citrate-modified evaporation-induced self-assembly method are demonstrated to be potential cathodes for Ni–YSZ anode supported IT-SOFCs with high power density.
