The maritime industry is under increasing pressure from environmental regulations, and therefore, it is required to provide energy solutions that comply with sustainable practices immediately. The study conducted by the researchers indicates the creation of a hydrogen fuel cell model that is designed specifically for the MATLAB Simulink high-speed passenger vessels. A detailed analysis sketch is laid out, which shows the design and simulation of the Proton Exchange Membrane Fuel Cell (PEMFC) system, displaying the emission reduction effect of this technology. This model is made up of extra units like a fuel cell stack, a DC/DC converter, and a flow rate regulator these give the operator the capability to change the fuel consumption and the generated power. Several scenarios were tested in simulation and results were compared to study system efficiency and performance, where the findings mostly focused on the role of hydrogen pressures in increasing cell voltage and efficiency. This study proves the potential of hydrogen fuel cells in sustainable maritime propulsion. It discusses the engineering challenges that are met during the experimental deployment and test in naval conditions.
