Basics

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
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
