“…X‐rays diffraction patterns reveal that all samples have the orthorhombic phase of the lanthanum chromite with Pnma space group ( Figure ) (ICSD #51191) . Nickel solubility limit in LaCrO 3− δ was reported to be close 20 at%; nevertheless, no diffraction peaks of NiO are detected in the patterns of the investigated samples .…”

A fast and accurate experimental method is demonstrated to assess the fraction of exsolved metallic nanoparticles using magnetic measurements. As a benchmark, nanometric metallic nickel exsolved from (La1−xSrx)(Cr1−yNiy)O3−δ is used for its high relevance as a solid oxide fuel cell component. The method is based on the difference in the magnetic response of the exsolved metallic nickel (ferromagnetic) and Sr‐doped lanthanum chromite ceramic matrix (paramagnetic). The exsolved nickel results in coherent nanoparticles pinned on the surface of the Sr‐doped lanthanum chromite ceramic matrix, as evidenced by electron microscopy analyses. The results obtained indicate the procedure as a fast and sensitive method to study the exsolution of ferromagnetic nanoparticles.

Solid oxide fuel cells (SOFCs) are the most widely used fuel cells due to their excellent fuel flexibility, high efficiency and low emissions. Although the liquid fuels are easier to handle and transport than hydrogen, their direct use in SOFC leads to serious performance deterioration because of the coke formation on the traditional Ni‐based cermet anodes. In this review, the advances in the development of coking resistant anodes and the new liquid fuels such as oxygenated hydrocarbons to solve the problem of coke formation with Ni‐based anodes are summarized. It is concluded that Ni‐based cermets are still the most promising anode materials and some targeted modifications are needed to improve the coking resistance. Several strategies to improve the coking resistance of Ni‐based anodes are highlighted. The aim of this review is to provide some helpful guidance and potential directions for the future design of anodes for SOFCs utilizing liquid oxygenated hydrocarbon fuels directly.

“…However, spin coating has gained attention as a method to produce thin layers for SOFCs, which can be used for layer depositions for both electrolyte-and anode-supported cells [10][11][12][13][14][15][16][17][18][19]. Such technique is based on the deposition by rotation in which a suspension is spread across the surface of a substrate by a centrifugal acceleration.…”

“…Such technique is based on the deposition by rotation in which a suspension is spread across the surface of a substrate by a centrifugal acceleration. It is a widely used technique in the electronic industry, in microlithography for the manufacture of integrated circuits and for fabrication of antireflective coatings in solar cells [10][11][12][13][14][15][16][17][18][19]. Spin coating has been successfully developed to fabricate both porous electrode layers and dense electrolyte films for anode supported SOFCs, evidencing the suitability of such deposition technique [10][11][12][13][14][15][16][17][18][19].…”

Electrodes for electrolyte-supported solid oxide fuel cells (SOFC's) were fabricated by spin coating. 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.
