A '''solid oxide fuel cell''' (or '''SOFC''') is an [[Electrochemistry|electrochemical]] conversion device that produces electricity directly from [[oxidizing]] a [[fuel]]. [[Fuel cell]]s are characterized by their electrolyte material; the SOFC has a solid oxide or [[ceramic]] electrolyte.

Advantages of this class of fuel cells include high combined heat and power efficiency, long-term stability, fuel flexibility, low emissions, and relatively low cost. The largest disadvantage is the high [[operating temperature]] which results in longer start-up times and mechanical and chemical compatibility issues.<ref>{{cite journal|last1=Badwal|first1=SPS|title=Review of Progress in High Temperature Solid Oxide Fuel Cells|journal=Journal of the Australian Ceramics Society|volume=50|issue=1|url=http://www.austceram.com/JAC-2014-1/ACS-Journal-2014-v1-23|url-status=dead|archive-url=https://web.archive.org/web/20141129041316/http://www.austceram.com/JAC-2014-1/ACS-Journal-2014-v1-23|archive-date=29 November 2014}}</ref>
