Numerical Study of Proton Exchange Membrane Fuel Cell (PEMFC) on Commercial Ships by Using ANSYS FLUENT
Abstract
Hydrogen Fuel Cell (HFC) is a clean technology that generates electricity through an electrochemical reaction which converts chemical energy of hydrogen into electricity through an oxidation reaction of hydrogen over a proper catalyst and produces water as a by-product. Hydrogen Fuel Cell has a high efficiency and zero emissions which make it a good choice to use on commercial ships in order to comply with international maritime regulations in terms of reduction of GHG emissions. In this paper, a Proton Exchange Membrane Fuel Cell (PEMFC) installed onboard chemical tanker is researched. A numerical investigation of its performance is conducted using Ansys Fluent. The CFD value of generated power shows a good agreement with the experimental value by 98.2%. The obtained results show a good temperature distribution over the cell and a regular reduction of hydrogen and oxygen density along both channels of anode and cathode which resemble the theoretical aspects of hydrogen fuel cell working principles and make a basis of researching its economic feasibility onboard commercial ships.
