Integration of solid oxide fuel cell and internal combustion engine for maritime applications

The current literature on solid oxide fuel cell and internal combustion engine (SOFC-ICE) integration is focused the application of advanced technologies operating as bottoming cycles to generate a small load share. This approach can pose challenges for ships such restricted dynamic capabilities large space weight requirements. Furthermore, potential SOFC-ICE marine power generation has not been explored. Consequently, work proposes novel maritime applications, which allows high-efficiency while SOFC anode-off gas (AOG) blended with natural (NG) combusted in spark-ignited (SI) combined generation. objective this paper investigate proposed respect system efficiency, emissions, sharing, considerations response. In work, verified zero-dimensional (0-D) model, experiments validated AOG-NG mean value model used. study found that integration, 67–33 split at 750 kWe output, yielded highest efficiency improvement 8.3% over conventional engine. Simulation results showed promising improvements 5.2%, UHC NOx reductions about 30% CO2 12% be achieved from 33–67 comparatively much smaller increments size 1.7 times. concluded favours ICE would significantly improve possible sudden changes met by ICE.
