“…Typically, SOFC research has been focused on reducing operative temperatures from 1000 • C to, e.g., 600 • C [3,4]. To address this issue, thin-film techniques are being explored to reduce the thickness of the electrolyte from millimeters to micrometers [5] or by using materials that have high ion conductivity and no electron conductivity [6]. However, fuel cell electrolytes need to be dense enough to prevent a cross-over phenomenon where anode gas is mixed with cathode gas.…”

Clean energy devices are essential in today’s environment to combat climate change and work towards sustainable development. In this paper, the potential materials A2Ce2O7−δ (A = La+3, Nd+3, Bi+3) were analyzed for clean energy devices, specifically for conventional and single-component solid oxide fuel cells (SC-SOFCs). The wet chemical route has been followed for the preparation of samples. X-ray diffraction patterns showed that all three samples exhibited a defected fluorite cubic structure. It also revealed the presence of dopants in the ceria, which was confirmed by the fingerprint region of FTIR. The optical behavior, fuel cell performance and electrochemical behavior were studied by UV–vis, fuel cell testing apparatus and EIS, respectively. The SEM results showed that all samples had irregular polygons. In Raman spectra, the F2g mode corresponding to the space group (Fm3m) confirms the fluorite structure. The Raman spectra showed that A2Ce2O7−δ (A = La+3, Nd+3, Bi+3) have different trends. The conventional fuel cell performance showed that the maximum power density of Bi2Ce2O7 was 0.65 Wcm−2 at 600 °C. The performance of A2Ce2O7−δ (A = La3+, Nd3+, Bi3+) as a single-component fuel cell revealed that Nd2Ce2O7−δ is the best choice with semiconductors conductors ZnO and NCAL. The highest power density (Pmax) of the Nd2Ce2O7/ZnO was 0.58 Wcm−2, while the maximum power output (Pmax) of the Nd2Ce2O7/NCAL was 0.348 Wcm−2 at 650 °C. All the samples showed good agreement with the ZnO as compared to NCAL for SC-SOFCs.

“…The limited performances of LT-SOFCs are attributed to several factors, such as low ionic conductivity (<0.1 S cm À1 ) of conventional electrolyte materials such as yttria-stabilized zirconia (YSZ), as well as sluggish electrode reactions resulting from the low catalytic activity (Alipour et al, 2022;Fan et al, 2022;Zhu et al, 2021a). The incorporation or in situ manufacture of active nanocomponents to form the nanocomposite might be a solution to these problems (Mushtaq et al, 2021b;Tabassum et al, 2019).…”

“…The applications of such fuel cells are diverse: aerospace, the automotive industry, small and large power plants, portable power generators, combined heat power engineering and reserve power supplies [ 5 , 6 ]. Nevertheless, the widespread introduction and mass commercialization of classical SOFCs are largely limited by their high operating temperatures, which impose stringent requirements for the structural and functional materials used in the fuel cell, accelerating the degradation of the power properties of the device as a whole, thereby increasing the cost of the electricity generated [ 7 , 8 ]. There are two different ways of solving this problem: searching for new materials whose performance in the intermediate-temperature range is not inferior to that of high-temperature materials and reducing the thickness of the SOFC’s main components (electrodes and electrolyte) in order to minimize the total resistance of the device [ 9 , 10 ].…”

In this paper, NiO, La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) and (CeO2)0.8(Sm2O3)0.2 (SDC) nanopowders with different microstructures were obtained using hydrothermal and glycol–citrate methods. The microstructural features of the powders were examined using scanning electron microscopy (SEM). The obtained oxide powders were used to form functional inks for the sequential microextrusion printing of NiO-SDC, SDC and LSCF-SDC coatings with resulting three-layer structures of (NiO-SDC)/SDC/(LSCF-SDC) composition. The crystal structures of these layers were studied using an X-ray diffraction analysis, and the microstructures were studied using atomic force microscopy. Scanning capacitance microscopy was employed to build maps of capacitance gradient distribution over the surface of the oxide layers, and Kelvin probe force microscopy was utilized to map surface potential distribution and to estimate the work function values of the studied oxide layers. Using SEM and an energy-dispersive X-ray microanalysis, the cross-sectional area of the formed three-layer structure was analyzed—the interfacial boundary and the chemical element distribution over the surface of the cross-section were investigated. Using impedance spectroscopy, the temperature dependence of the electrical conductivity was also determined for the printed three-layer nanostructure.
