“…The proton thus created can move freely, improving conductivity. [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.

Reversible protonic ceramic electrochemical cells (R‐PCECs) are very promising as energy conversion and storage devices with high efficiency at intermediate temperatures (500–700 °C). Unfortunately, the sluggish reaction kinetics on air electrodes severely hamper the commercial application of R‐PCECs. In this work, an In‐doped PrBaCo2O5+δ air electrode is developed with a designed formula of PrBaCo1.9In0.1O5+δ, which however consists of a dominated double perovskite PrBa0.95Co1.85In0.09O5+δ and a minor cubic perovskite BaCo0.85In0.15O3‐δ phase, as suggested by the XRD refinements. The formation of nanocomposites induced by the In‐doping has markedly improved the activity of oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), due likely to the increased oxygen vacancies, enhanced the oxygen surface exchange and bulk diffusion capabilities when compared to the bare PrBaCo2O5+δ. Excellent electrochemical performances in fuel cell (FC) mode (2.25 W cm−2) and electrolysis cell (EC) mode (−4.41 A cm−2 at 1.3 V) are achieved on the single cells with such nanocomposite air electrodes at 700 °C. In addition, promising durability tests of cells in modes of FC (100 h), EC (100 h), and cycling (210 h) are demonstrated at 600 °C. This In‐doped strategy provides a novel approach to developing new air electrode materials.
