High Resolution Image Download MS PowerPoint Slide Extensive research has been conducted on solid oxide electrolysis cells (SOECs) as advanced electrolysis technologies for the electrochemical conversion of CO 2, H 2 O, and H 2 O/CO 2 mixtures into syngas, i.e., CO, H 2, and H 2 /CO. SOECs demonstrate high-energy conversion efficiencies in the electrolysis of H 2 O and CO 2, enabling the sustainable production of hydrogen and low-carbon fuels. Recent research efforts have focused on enhancing key components of SOEC to improve their performance and durability, thereby promoting their integration in practical energy conversion and storage applications. Nevertheless, the absence of highly active and stable electrodes in SOEC remains a significant challenge, limiting the practical application of H 2 O/CO 2 electrolysis in these systems. This review presents a comprehensive overview of SOECs background, encompassing its fundamental mechanism, the development of electrodes and electrolyte materials, and the key challenges affecting performance. It highlights nanoengineering techniques designed to reduce overpotentials, with a particular focus on advancing the core components of SOECs, i.e., electrodes and electrolytes. Nanoengineering techniques demonstrate the potential to enhance the conductivity of fabricated SOECs devices even at low temperatures, thereby improving the efficiency, durability, and lifespan of SOEC. Additionally, the review addresses existing challenges and outli...
