AB Lowering the operating temperature of solid oxide fuel cells (SOFCs) is crucial tomake this technology commercially viable. In this context, the electrode e ciency at lowtemperatures could be greatly enhanced by microstructural design at the nanoscale. This workdescribes alternative microstructural approaches to improve the electrochemical e ciency of theBaCo0.4Fe0.4Zr0.1Y0.1O3-  (BCFZY) cathode. Di erent electrodes architectures are prepared in asingle step by a cost-e ective and scalable spray-pyrolysis deposition method. The microstructureand electrochemical e ciency are compared with those fabricated from ceramic powders andscreen-printing technique. A complete structural, morphological and electrochemical characterizationof the electrodes is carried out. Reduced values of area specific resistance are achieved for thenanostructured cathodes, i.e., 0.067 W cm2 at 600  C, compared to 0.520 W cm2 for the same cathodeobtained by screen-printing. An anode supported cell with nanostructured BCFZY cathode generatesa peak power density of 1W cm􀀀2 at 600  C.
