Application analysis of a hybrid solid oxide fuel cell-gas turbine system for marine power plants

The results of theoretical studies the possibilities using hybrid solid oxide fuel cell–gas turbine (SOFC-GT) systems for marine power plants are presented. A 500 kW auxiliary plant scheme stacks SOFCs in combination with a regenerative gas operating over-expansion based on our recent patent application is proposed. mathematical modelling showed opportunity to obtain efficiency about 55% optimal values compression ratio 2.0–2.2 and exhauster compressor 1.3–1.4. considered SOFC-GT system gives an increase electrical by 19% comparison cycle without turbine. aerodynamic structure chemically reacting flows combustor determined, as well features formation toxic components during combustion SOFC off-gas very low heating value.
