Solid Oxide Fuel Cells (SOFCs) have emerged as a highly promising solution in the transition toward sustainable and decentralized energy systems. Operating at high temperatures, SOFCs enable efficient electrochemical energy conversion with minimal pollutant emissions. Beyond their operational efficiency, SOFCs offer unique advantages such as fuel flexibility, long service life, and low emissions of nitrogen oxides, particulates, and unburned hydrocarbons. Furthermore, their reversible operation mode enables them to function as Solid Oxide Electrolyzers (SOEs), allowing for efficient hydrogen production and energy storage. Despite these benefits, a comprehensive evaluation of their life cycle environmental impacts is essential to validate their role in sustainable energy systems.
