In order to benefit from the high electrochemical efficiency of solid oxide fuel cells, a skillful balance of plant has to be developed. An energetic and economic analysis of a decentralized natural gas-fueled SOFC-power plant in the range of 200 kW capacity is presented. Starting from a simple flowsheet process concepts with external and internal reforming and gas recycling by blowers or jet boosters are described. Cathode gas recycling by jet booster turns out to be more advantageous with respect to electricity production cost than gas recycling by hot gas fans. Cost analysis is applied to such plant concepts.
