A Solid Oxide Fuel Cell (SOFC) is a high-temperature electrochemical device that converts chemical energy from a fuel, typically hydrogen, carbon monoxide, or hydrocarbons, directly into electricity with high efficiency. It operates using a solid ceramic electrolyte, commonly made of yttria-stabilized zirconia (YSZ), which conducts oxygen ions (O²⁻) at elevated temperatures, usually between 600°C and 1,000°C.
Key features of SOFCs:
Environmentally friendly (low NOₓ, SOₓ, and CO₂ emissions when used with clean fuels)
How it works:
At the anode, the ions react with the fuel to generate electricity, heat, and byproducts (like water or CO₂).
Common applications:
Future potential for distributed and residential energy systems
SOFCs are particularly suited for long-duration, high-efficiency energy systems and are under active development for broader commercial deployment.
