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.

“…A new configuration of an integrated SOFC and gas turbine (GT) combined with a biogas reforming cycle for the cogeneration of power and H 2 was proposed by Soleymani et al [34]. The thermal energy discharged from the SOFC-GT system is used to supply the energy required for the reforming reaction in the biogas reforming cycle for H 2 production.…”

“…Dry reforming of methane (DRM) is a process that simultaneously converts methane and carbon dioxide, two of the major greenhouse gases, allowing the utilization of biogas or sources of natural gas with high levels of CO 2 1,2 . The main product is a mixture of H 2 and CO (syngas) that presents many potential applications as fuels or chemicals 3‐6 . Syngas production with low H 2 /CO ratio (equal to 1) is proper for Fischer–Tropsch process and synthesis of methanol and dimethyl ether 2,7‐9 .…”

Ni-Al-LDH catalyst was modified with Cu to improve catalyst activity and deactivation resistance in biogas reforming. The samples were obtained by impregnation of Cu on Ni-Al previously prepared by coprecipitation, and characterized by X-ray diffractometry, N 2 physisorption, temperatureprogrammed reduction, CO 2 temperature-programmed desorption, and temperature-programmed oxidation. Catalytic tests were performed with CH 4 / CO 2 = 1.5 at 600 and 700 C in a fixed bed reactor. The characterization results revealed that the presence of Cu facilitates the reduction of Ni 2+ to Ni . The washing step influences the properties of the catalyst, since samples with low Cu content showed greater activity and stability than catalysts with high Cu content. At 700 C, the best results were obtained with the unreduced catalyst, with CH 4 conversions above 75%, because the reduction with H 2 at such condition causes catalyst sintering. No deactivation was observed at 600 C. The results achieved by the unreduced catalysts show potential for the production of H 2 as they do not require theactivation with H 2 . A mechanism for activating the catalyst with CH 4 was proposed.
