The primary components of SOFCs are the anode, cathode, and the electrolyte. Anode is critical in achieving the effective electrochemical oxidation of fuel; thus, its performance can be improved using homogenous powder synthesized through an appropriate method. Various synthesis methods, including solidstate reaction and wet chemical methods have been used to synthesize anode materials. However, each technique has several advantages and disadvantages.Given that anode is a porous electrode, few criteria, such as high conductivity, tolerance towards carbon deposition, chemical stability, and thermal stability, must be fulfilled. Researchers also modified the existing synthesis method to improve the performance of the anode. In addition, various anode fabrication techniques including physical and colloidal deposition techniques are briefly discussed to understand their effect on the performance of the deposited layers.The aim of this review is to discuss the various anode synthesis and deposition techniques and their influence on the properties and performance of SOFCs.

“…In the case of LSF and LNF, the resulting powders were pelletized and calcined in air at 950 C for 8 h to obtain pure single phase samples. The properties (composition, morphologies, TEC and conductivities) of the primary materials used in the present study could be consulted in previous works [46].…”

Available online xxxKeywords: SOFC Wet powder spray Cathode Active layers Ball milling a b s t r a c t sIn this work, a wet powder spraying method has been investigated as a facile low cost route to deposit electrode layer on SOFC electrolyte support. A particular focus has been examining the interfacial stability of the deposited layers, and determining the influence of the thickness of the different layers, as well as the ball milling regime used to produce the electrode inks.The developed system consist of an yttria stabilized zirconia electrolyte support, a La 0.6 Sr 0.4 FeO 3 (LSF) cathode, a Sm 0.2 Ce 0.8 O 1.9 (SDC) barrier layer between the electrolyte and the cathode, and LaNi 0.6 Fe 0.4 O 3 (LNF) as a contact layer, for a future integration with the SOFC interconnector. The electrolyte supports (300 mm thickness and 9 mm diameter) supports were prepared by uniaxial pressing, while the deposition of thin barrier layers, cathode and contact layer were carried out by manual spray coating.Please cite this article as: Wain-Martin A et al., SOFC cathodic layers using wet powder spraying technique with self synthesized nanopowders, International Journal of Hydrogen Energy, https://doi.

Alumina/YAG composites (AYX_t) with high relative density (99.2 %TD) were successfully obtained by mixing commercial alumina powder with different volume fractions of yttrium aluminium garnet (Y 3 Al 5 O 12-YAG; 7, 14, 21 and 28). YAG was synthetized by nitrate glycine reaction in the form of precursor powder. Polycrystalline YAG powder was obtained by calcination at 950 °C for 2 h. Additionally, obtained compositions were characterized by XRD, SEM, EDX and electrochemical impedance spectroscopy. By XRPD analysis was found that the particle size of YAG powders lies in the nanometric range (being lower than 35 nm). By SEM microphotographs of composites were confirmed the formation of a conductive path consisting from mutually interconnected YAG particles. This was confirmed by the electrochemical impedance spectroscopy. The highest electrical conductivity of grain (κ g) and grain boundary (κ gb) at 700 ºC amounted to 2.22×10-2 Ω-1 cm-1 and 9.44×10-3 Ω-1 cm-1 , respectively, was measured in the composite containing 21 vol% of YAG.
