Abstract
Considering the recent official targets by the authorities to 100% phase out sales or registrations of new internal combustion engines (ICE) that use gasoline, battery and fuel cell technologies have been suggested. In two different scenarios, this study evaluates the possibility of integrating proton exchange membrane fuel cells to two different types of Li-Ion batteries to provide 800kW power for a ferry with a total length of 50.8m to transport 780 passengers for a distance of 24km in 70mins. The optimized results indicate that the total size, and hydrogen consumption of around 8.34m3, and 36.1 kg/h, respectively, are needed in the first scenario to reach the maximum power of 800kW with 49.5% overall efficiency. The operating power of the integrated battery and fuel cell system is between 80kW to 720 kW, which is 10% to 90% of the maximum power. In the second scenario, the corresponding values of the size, and hydrogen consumption are 8.23 m3, and 36 kg/h to reach the same power by the overall efficiency of 49.6%. The first scenario uses 8 modules of PEMFCs and one module of NMC while the second scenario uses LTO as the battery with the same numbers of PEMFCs.
