A solid oxide fuel cell (SOFC) is a type of fuel cell that uses solid oxide electrolytes to produce electricity through an electrochemical reaction. Known for their high efficiency and versatility, SOFCs are attracting significant interest for various applications, including power generation, industrial processes, and transportation. Operating at high temperatures, typically between 600°C and 1,000°C, SOFCs use a solid ceramic electrolyte to conduct oxygen ions from the cathode to the anode. At the cathode, oxygen from the air is reduced to form oxygen ions, which then migrate through the electrolyte to the anode. Here, these ions react with hydrogen or carbon monoxide to produce water, carbon dioxide, and electrons.
This process generates electricity, which can be used to power electrical devices or systems. One of the key advantages of solid oxide fuel cell is their high efficiency, with electrical efficiencies reaching up to 60% and overall system efficiencies up to 85% when used in combined heat and power (CHP) systems.
