Abstract

In this work, powders of La~0.6~Sr~0.4~Fe~0.8~Co~0.2~O~3–δ~ were prepared by the auto‐combustion of ethylene glycol–metal nitrate polymerised gel precursor. This method (polymeric organic complex solution) allows decreasing the processing temperature and simplifies the whole procedure. A single phase material is obtained at 300 °C lower than that needed by conventional solid state reaction (SSR). The reduced particle size and low agglomeration increases the reactivity of powders and therefore, the sintering temperature is also reduced in 200 °C with respect to the conventional SSR method. As a consequence of that, the microstructures are controlled maintaining the grain size in an almost nanometric range.

One of the primary scientific aims within the solid oxide fuel cell (SPOFC) community is to lower the operating temperature of an SOFC system from about 800-1,000 °C to intermediate temperatures of about 600 °C [1]. The lower operating temperature decreases thermal stress in the materials and offers

Solid oxide fuel cells (SOFCs) are becoming promising candidates for highly efficient energy generation from conventional and biomass-derived fuels due to different reasons: (i) electricity can be obtained directly from a fuel; (ii) the subproduct is a high quality hot gas stream, usable in (micro)t
