Editing Solid oxide fuel cell (section)

===SOEC===
A [[solid oxide electrolyser cell]] (SOEC) is a solid oxide fuel cell set in [[Regenerative fuel cell|regenerative mode]] for the [[electrolysis of water]] with a solid oxide, or [[ceramic]], [[electrolyte]] to produce oxygen and [[hydrogen gas]].<ref>{{cite journal | author1=Anne Hauch | author2=Søren Højgaard Jensen | author3=Sune Dalgaard Ebbesen | author4=Mogens Mogensen | title=Durability of solid oxide electrolysis cells for hydrogen production | journal=Risoe Reports | year=2009 | volume=1608 | pages=327–338 | url=http://www.risoe.dk/rispubl/reports/ris-r-1608_327-338.pdf | url-status=dead | archive-url=https://web.archive.org/web/20090711161522/http://www.risoe.dk/rispubl/reports/ris-r-1608_327-338.pdf | archive-date=11 July 2009 | df=dmy-all }}</ref>

SOECs can also be used to do electrolysis of CO<sub>2</sub> to produce CO and oxygen<ref>{{cite journal |author1=Rainer Küngas
