AB La2CuO4þd cathode layers are prepared by spray-pyrolysis deposition and their structural, microstructuraland electrical properties are compared with those of submicrometric powders obtained fromfreeze-dried precursors. In order to improve the cathode performance, three different electrode architectureshave been proposed: (i) powder cathodes obtained by conventional screen-printing and sintering,and cathodes deposited by spray-pyrolysis on: (ii) as-prepared electrolyte surfaces and (iii) porouselectrolyte backbones. The cathode activity for the oxygen reduction reaction has been investigated as afunction of the microstructure and the sintering temperature. The microstructural optimization of thecathodes and the low fabrication temperature minimize the instability problems between the electrolyteand the cathode materials, leading to polarization resistances as low as 0.14 U cm2 at 600  C.
