Diesel-fueled fuel cell systems can be more clean and efficient energy solutions than internal combustion engines for electric power generation on-board naval surface ships. NATO Navy steam and gas turbine and diesel ships are powered by a naval distillate fuel (NATO symbol F-76). In this study, a 120 kW F-76 diesel-fueled solid oxide fuel cell system (SOFC) as an auxiliary engine on-board a naval surface ship was designed and thermodynamically analyzed. A diesel-fueled SOFC system was compared to diesel-electric generator set in a case naval surface ship.
