Application of PEM fuel cell in different traditional propulsion systems for harmful emission reduction

Today’s propulsion technology in sea and road transport is driven by legislations focused on emission reduction. This has even higher importance in highly populated cities and harbors where the number of commercial vessels and vehicles increases with population size. They are typically diesel fueled, and in city areas and harbors during maneuvering, operate at low speeds and loads. This results in significant greenhouse gases and exposure to diesel exhaust, which is comprised primarily of particulate matter and oxides of nitrogen. Hydrogen fueled polymer electrolyte membrane (PEM) fuel cell technology is a technology to reduce the environmental impact of the transport sector. Life cycle analysis of fuel cell vehicles as well as optimum integration strategy of the PEM fuel cell in hybrid system was studied in this article. The PEM fuel cell was designed to reduce the additional pollution created by auxiliary loads. Several simulations were performed with fully loaded cargo weight and with all possible auxiliary loads in different cycles. By integrating PEM fuel cell to cover auxiliary power and simulating it on realistic driving cycle, the shift of powering the auxiliary loads from internal combustion engine to PEM fuel cell has shown reduction in diesel fuel consumption as well as CO2 reduction.
