“…Based on their work, the authors concluded that CuO is the most optimal sintering agent the proton‐conducting BZCYYb electrolyte to be used for PCECs. Although no positive densification was found for the ZnO‐containing material, a subsequent work [ 165 ] reported the strategy of adding Zn to Y and Yb co‐doped barium cerate‐zirconate to successfully decrease the sintering temperature and develop a highly dense BaCe 0.5 Zr 0.3 Y 0.1 Yb 0.05 Zn 0.05 O 3–δ electrolyte having high ionic conductivity in the intermediate temperature range. These disagreements may be associated with different concentrations of the Zn‐dopant.…”

Proton‐conducting oxide materials are interesting objects from both fundamental and applied viewpoints due to the origination of protonic defects in a crystal structure as a result of their interaction with hydrogen‐containing atmospheres at elevated temperatures. The high mobility of such defects at temperatures between 400 and 700 °C leads to superior ionic conductivity. As a result, some perovskite‐type proton‐conducting oxides have been proposed as electrolytes for solid oxide fuel and electrolysis cells. Barium cerate (BaCeO3), barium zirconate (BaZrO3), and barium cerate‐zirconates (BaCeO3–BaZrO3) have been widely studied in terms of the parent phases of proton‐conducting electrolytes. Among them, Y and Yb co‐doped Ba(Ce,Zr)O3 can be identified as one of the most promising systems so far. This review discloses key functional properties of such phases and explains the increased attention of researchers to this system.

“…[88,90] Norman et al [91] noted that co-doping of cerate-based electrolyte with transition-metal (In) enhances the chemical stability, sinterability, and ionic conductivity. A perovskite-type BaCe 0.5 Zr 0.3 Y 0.1 Yb 0.05 Zn 0.05 O 3Àδ electrolyte was prepared by Afif et al [92] which showed high density, good protonic conductivity, as well as peak power density in the intermediate temperature range (700 °C).…”

Solid oxide fuel cells (SOFCs) hold an important place in energy conversion and storage systems due to their fuel flexibility, high efficiency, and environmental sustainability. The scorching temperature (≥ 800 °C) to operate SOFCs results in shorter lifespan due to rapid deterioration of accompanying components. Nanomaterials have attained considerable attention in recent years due to their great technological importance in fuel cell technology. Nanoengineering of the architectures of known materials and adopting composite approach can effectively enhance the active sites for electrode reactions. The use of nanotechnology will make SOFCs environment‐friendly and sustainable through green manufacturing processes of nanotechnology. Overviews of the contributions of nanotechnology and power electronics technologies to SOFCs, the transition of SOFCs from macro to nanotechnology, the significance of nanomaterials in SOFCs, dynamic modeling, the function of optimization techniques, and the requirement for power electronics converters in SOFCs are all provided in this piece of work. The applications of SOFCs in different sectors, prominent institutes/labs and companies involved in SOFCs’ research, future challenges and perspectives were also highlighted.This article is protected by copyright.

“…Updated proton conductivity of roughly 0.01 Scm -1 is demonstrated by several perovskites that contain Ba and Sr, such as BaCe 0.9 Y 0.1 O 3 [11][12][13][14]. Meanwhile, materials based on BaCeO3 and BaZrO3 showed strong conductivity and better chemical stability [15][16][17][18]. At the intermediate temperature range, a proton-conducting electrolyte, BaCe 0.7 Zr 0.25-x Y x Zn 0.05 O 3 has been developed recently and showed a highly conductive and dense electrolyte [19,20].…”

A possible component of power generation technologies, solid oxide fuel cells (SOFCs) offer a high fuel-to-power conversion efficiency and no negative environmental impact. The solid-state sintering process was used to synthesize the scheelite-structured Sr0.9La0.1WO4 (SLW1) electrolyte material, and phase stability and ionic conductivity were evaluated for their technological applicability for SOFC applications. The resulting mixture, which was a single phase in a tetragonal crystal system, produced a scheelite structure of the space group I41/a. Its symmetry, space group, and structural characteristics are confirmed by X-ray diffraction (XRD) at room temperature and the Rietveld analysis that follows. A highly dense crystal structure was revealed by SEM examination. The ionic conductivity of the SLW1 sample is higher than SBW materials and lower than the conventional BCZY perovskite structure. At 900°C in both the wet Ar and dry Ar conditions, the SLW1 sample’s ionic conductivity was 2.41 × 10−5 S cm-1 and 1.76 × 10−5 Scm−1. This scheelite-like compound showed a thick microstructure and substantial conductivity, making it a potential mixed ion-conducting electrolyte for SOFC.
