Strontium- doped lanthanum manganite (LSM) cathode and nickel yttria-stabilized zirconia cermet anodes were synthesized and processed for enhanced deposition conditions. The influence of electrode microstructural parameters was investigated by a systematic experimental procedure aiming at optimized electrochemical performance of single cells. Polarization curves showed a strong dependence on both electrode thickness and sintering temperature. By a systematic control of such parameters, the performance of single cells was significantly enhanced due to decreasing of polarization resistance from 26 Ω cm² to 0.6 Ω cm² at 800°C. The results showed that spin-coated electrodes can be optimized for fast and cost effective fabrication of SOFCs.openAccessanodescathodesdoped materialselectrodeslanthanumlayersoptimizationperformancesolid oxide fuel cellsspin-on coatingsstrontiumx-ray diffractionArtigo de periódico12210.1590/S1517-707620170001.0136https://orcid.org/0000-0003-0708-20213.33
