Various Well-Designed Hydrogen Fuel Cells: Structure, Principle, and Advantages

Nowadays, with the increasing use of fossil fuels, more and more environmental problems appear, like global warming and air quality degradation. In different industries that use fossil fuels as fuel, the harmful greenhouse gases emitted by car engines account for a large proportion. This paper will discuss the hydrogen fuel cells used for vehicles nowadays, which consist of three different kinds. These hydrogen fuel cells have similar structures, only different in some specific sectors. They have many advantages over traditional fossil fuels, like higher efficiency and lower carbon dioxide emissions. The basic structure, development process, principle, and catalysts needed for reaction will be introduced. Also, the advantages of each of the fuel cells will be discussed compared to others. The study of hydrogen cells in this paper can help understand its benefits. By promoting the development of hydrogen fuel cells, there will be more clean and efficient energy options in the future.
