Solid Oxide Fuel Cell (SOFC)

H₂ + ½O₂ → H₂O

ภาพรวม

SOFCs operate at 600–1000°C using a solid ceramic oxide electrolyte that conducts O²⁻ ions. Oxygen is reduced at the cathode and transported through the electrolyte to oxidize hydrogen (or hydrocarbon fuel) at the anode. Efficiency reaches 60% electrical, or 85%+ in combined heat and power mode. SOFCs can run on natural gas directly.
