“…A ceramic material or dense layer solid oxide electrolyte was used in SOFCs which have the capacity of carrying oxygen ions and negligible or no electronic conduction to reduce the current leakage. The materials should be compatible with electrodes such as cathode and an anode and should be stable mechanically and chemically as well [10,17]. The working mechanism of the SDCC superionic transport due to proton and ionic conductive (coexistence) phases are as shown in Fig.…”

There is a growing interest in solid oxide fuel cells (SOFCs) technology among the researchers a promising power generation with high energy efficiency, inflated fuel flexibility, and low environmental impact compared to conventional power generation systems. SOFCs are devices in which the chemical energy is directly converted into electrical energy with negligible emission. SOFCs have low pollution characteristics, high efficiency (~ 60%), and possess expanded fuel selection with little environmental effects. A single cell component of SOFCs is consisting an anode, cathode and an electrolyte which are stacked layer by layer to produce higher amount of power. The dense ceramic electrolyte transporting O2− ions and fills the space between the electrodes material. Redox reaction occurred at the electrodes side in the presence of fuels. The operating temperatures of SOFCs of 600–1200 °C which produced heat as a byproduct and fast electro-catalytic activity while using nonprecious metals. Many ceramic materials have been investigated for SOFCs electrolyte. Yttria-stabilized zirconia (YSZ) material was extensively used as dense electrolyte in SOFCs technology. In this review, the article presents; overview of the SOFCs devices and their related materials and mostly reviewed newly available reported.

“…Among the different configurations, this study is focused in planar SOFCs, which have a much simpler manufacturing process and lower fabrication cost than those of their tubular counterparts [12e14]. Regarding planar configuration, two types are preferred: electrode (mainly at anode) supported cells and electrolyte supported cells [3,15,16]. Although electrolyte supported cells may exhibit higher ohmic losses, they are more robust and have demonstrated much better stability during the reduction-oxidation processes and thermal cycles [17,18].…”

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.

Summary In accomplishment of massive energy demand, the solid oxide fuel cells (SOFCs) have proven as apotheosis candidates due to their high energy conversion efficiencies, low pollution exhaust, fuel flexibility, and environmental friendliness which make these the most promising alternatives to conventional electricity generators. Despite numerous advantages of SOFCs, large‐scale industrial applications are yet to be realized owing to their high operating temperatures (800°C‐1000°C). To lower the operating temperature, it is crucial to minimize ionic resistances which can be accomplished by reducing the electrolyte thickness to lesser than 5 μm. Therefore, present article embraces a concise review on conventional materials, designs, and generations of SOFCs with their compatibility and drawbacks. The strengths and limitations of conventional and advanced tools for fabricating thin film based SOFCs (TF‐SOFCs) as well as the associated properties of electrolytes and electrodes are thoroughly examined, and further route cast is provided to attain better performance. The present review encourages the development of TF‐SOFCs using advanced techniques employing ultrathin single and bilayer electrolytes which can have potential to reduce the operating temperature of SOFCs from 450°C to 600°C region and pave the way for global commercialization.
