摘要：	In this study, the U.S. Coast Guard (USCG) investigated the impact upon CGC VINDICATOR ship systems resulting from potential conversion to fuel cell propulsion and auxiliary power. VINDICATOR is a T-AGOS class monohull, 224- feet in length, powered by four Caterpillar diesel-electric generators with DC propulsion motors. USCG selected this vessel as a candidate for development and potential demonstration of fuel cell power on board ships. Space and weight limitations and marine operational requirements uncovered during this study are believed to be applicable to other ship installations. Detailed changes to structural, electrical, fuel delivery, exhaust management and related systems necessitated by removal of the four main diesel generators and replacement by four molten carbonate fuel cell modules were developed. Also developed was the outline design of each 625 kW molten carbonate fuel cell Demonstration Module, including fuel processing, fuel cell stacks, and inverter. A dynamic computer simulation model was created which linked the fuel cell performance to ship parameters including displacement, speed, and loading cycles. This information was used to analyze the ship integration impacts based on the fuel cell design. Included with this final summary report are outline figures of detailed removal and installation drawings detailing existing and proposed arrangements. Several conclusions are made. The proposed fuel cell modules are compatible with existing ship interfaces, with relatively minor modifications. The fuel cell modules are substantially larger than the diesel generators they replace, necessitating removal of the non-structural side shell within the main diesel generator room. Existing air handling, exhaust, and fuel delivery systems can be reused, ship performance (stability and seakeeping) is unchanged, and minor maneuvering performance changes may result. Increased range is expected due to the predicted higher efficiency of the fuel cells.
