Composites of Sr-doped LaMnO3 (LSM) and yttria-stabilized zirconia (YSZ) were prepared by sequential electrodeposition of La and Mn species from nitrate salts in Dimethyl Sulfoxide (DMSO) into porous, carbon-coated YSZ substrate, followed by the infiltration of Sr(NO3)2. The La and Mn species were uniformly deposited throughout the depth of 50 µm porous layer to the interface with a dense YSZ electrolyte. The LSM perovskite phase was formed after heating to 1373 K. Solid oxide fuel cell cathodes prepared by single-step electrodeposition showed similar performance to LSM-YSZ electrodes prepared by wet impregnation using many steps.
