How SOFC and SOEC work

SO Fuel Cells

Solid oxide fuel cells are a cutting-edge technology for converting the chemical energy in hydrocarbon fuels to electrical power and heat by means of an electrochemical reaction. SOFC technology has many advantages over conventional power trains, such as combustion engines, including:

  • high efficiency, including at small scale
  • fuel flexibility
  • insignificant NOx, SOx and particulate emissions, reduced CO2 emissions
  • silent and vibration-free operation.

SO Electrolysis Cells

Solid oxide electrolysis cells operate inversely to fuel cells, for storing electricity by producing a fuel with high energy density. This is especially interesting when the electricity generated from renewable sources exceeds the demand for electrical power (for example during very windy spells at night). Furthermore, it allows to produce fuels - for transport for example - which are renewable and that cause zero pollution at the point of use.
