“…Despite these challenges, IT-SOFCs and LT-SOFCs are generally viewed as more competitive from a commercial perspective. In recent years, two main solutions have been recognized as effective in reducing the operating temperature of SOFCs without significantly compromising performance [168]. One solution focuses on utilizing highly active component materials, starting with electrode materials of higher catalytic activity or electrolytes of higher ionic conductivity.…”

Solid Oxide Fuel Cells (SOFCs) are emerging as a leading solution in sustainable power generation, boasting high power-to-energy density and minimal emissions. With efficiencies potentially exceeding 60% for electricity generation alone and up to 85% when in cogeneration applications, SOFCs significantly outperform traditional combustion-based technologies, which typically achieve efficiencies of around 35–40%. Operating effectively at elevated temperatures (600 °C to 1000 °C), SOFCs not only offer superior efficiency but also generate high-grade waste heat, making them ideal for cogeneration applications. However, these high operational temperatures pose significant thermal management challenges, necessitating innovative solutions to maintain system stability and longevity. This review aims to address these challenges by offering an exhaustive analysis of the latest advancements in SOFC thermal management. We begin by contextualizing the significance of thermal management in SOFC performance, focusing on its role in enhancing operational stability and minimizing thermal stresses. The core of this review delves into various thermal management subsystems such as afterburners, heat exchangers, and advanced thermal regulation strategies. A comprehensive examination of the recent literature is presented, highlighting innovations in subsystem design, fuel management, flow channel configuration, heat pipe integration, and efficient waste heat recovery techniques. In conclusion, we provide a forward-looking perspective on the state of research in SOFC thermal management, identifying potential avenues for future advancements and their implications for the broader field of sustainable energy technologies.

Cu−Fe spinel has recently attracted considerable interest as a protective coating for solid oxide fuel cell steel interconnects. In this study, Cu−Fe spinel coatings were deposited on SUS 430 steel substrates via a coating route of the dip-coating process. Oxidation tests were investigated in laboratory air at up to 800 °C for five (5) 24 h (24 h) cycles up to 120 h. The areaspecific resistance (ASR) of the samples was measured by a standard four-probe method. The experimental results indicated that the CuFe 2 O 4 spinel powders with fine grain size were successfully synthesized from the sol−gel method. The oxidation kinetics of Cu−Fe spinel-coated steel obeyed a parabolic law, showing a parabolic rate constant of 1.38 × 10 −14 g 2 cm −4 s −1 . The ASR value of the coated samples was about 11.2 mΩ cm 2 at 800 °C. The Cu−Fe spinel coating improved both the high-temperature oxidation resistance and the electrical conductivity of the steel interconnects.

Protonic ceramic electrochemical cells (PCECs) have received extensive research attention as full solid‐state, electrochemical devices that can interconvert electrical and chemical energies via rapid proton conduction at reduced temperatures. Nonetheless, the practical application of PCECs still faces numerous challenges. In addition to the development of electrode materials, the protonic ceramic electrolytes (PCEs), which are crucial for the performance and stability of PCECs, encounter issues such as poor sinterability, low ionic conductivity, and inadequate thermochemical matching. To address these obstacles, the design and optimization of protonic ceramic electrolytes have recently become essential research focuses in the field of PCECs. To achieve effective customization of the elemental composition, crystal structure, defect structure, ionic conductivity, and chemical stability, many candidates for electrolyte materials with various compositions have been proposed. This review also covers state‐of‐the‐art developments in PCE fabrication technologies, including powder synthesis, thin‐film deposition, more controllable sintering processes and interface treatments for structural integrity and ionic conductivity. This review comprehensively summarizes the most recent design approaches and optimization strategies for perovskite‐based protonic ceramic electrolyte materials and is crucial for advancing the commercialization of PCECs.
