Comparative design analysis of a fuel cell powered Coast Guard cutter

摘要

This investigation studied the impact of using fuel cells as the primary power source in a ship design. Three different fuel cells were modeled: Phosphoric Acid, Proton Exchange Membrane, and Molten Carbonate. These models were compared against a baseline design containing a more conventional powerplant. The models were built and optimized using the 'Advanced Surface Ship Evaluation Tool' (ASSET/MONOSC). Specifically, payload, endurance, sustained speed, and hull depth were held constant, while length, beam, and draft were optimized to provide a balanced design. Full load displacement and required fuel load were compared against the baseline values. Conclusions concerning the potential value of a fuel cell powerplant were drawn.
