ABSTRACT
In recent decades, the application of fuel cells in vehicles has been the focus of increased attention. In contrast to a chemical battery, the fuel cell generates electric energy rather than storing it and continues to do so as long as a fuel supply is maintained. Compared with the battery-powered electric vehicles (EVs), the fuel-cell-powered vehicle has the advantages of a longer driving range without a long battery charging time. Compared with internal combustion engine (ICE) vehicles, it has the advantages of high energy efficiency and much lower emissions due to the direct conversion of free energy in the fuel into electric energy, without undergoing combustion.
