Ceramic Fuel Cell (CFC), or in their probably first definition – Solid Oxide Fuel Cell (SOFC), is a high temperature device that converts the chemical energy of fuel directly into electricity and heat. There are no intermediates in this process. Therefore, CFC as a fuel cell system can offer very high electrical efficiencies (twice as high as traditional converters like heat machines). They offer perspectives to decreasing fuel consumption for stationary (local combined heat and power, CHP), mobile (auxiliary power units, APU, or hybrid vehicles), or portable (battery replacer) applications, as well as reducing CO2, NOx and other pollutant emissions due to both much higher efficiency of energy conversion and comparatively low operating temperature. No moving parts are involved in the energy conversion process, which improves reliability and increases safety in the application.
However, some improvements are necessary to increase their reliability and make them cheaper.
