  • A solid oxide fuel cell (SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a fuel
  • Fuel cells are characterized by their electrolyte material and, as the name implies, the SOFC has a solid oxide, or ceramic, electrolyte
  • Advantages of this class of fuel cells include high efficiencies, long term stability, fuel flexibility, low emissions, and cost (cost is debatable, need more research on that bit?)
  • The largest disadvantage is the high operating temperature which results in longer start up times and mechanical/chemical compatibility issues.
    • The higher operating temperature make SOFCs suitable candidates for application with engines/power sources that reach a similar temperature, such as Internal Combustion Engines , especially if they use the same fuel such as CNG
