Research Progress on Different Types of Hydrogen Fuel Cells

Abstract

As a clean and sustainable form of energy, Hydrogen Fuel Cells are regarded as a part of the key technologies of renewable energy. Hydrogen fuel cells, as the core of a new type of energy, can generate electricity solely by consuming the raw material water. During the process of energy generation, no chemical pollution is produced, which plays a key role in energy security and environmental protection. This paper systematically reviews the research progress of hydrogen fuel cell technology through literature study, focusing on the working principles, technical characteristics and application status of proton exchange membrane fuel cells, alkaline fuel cells and anion exchange membrane fuel cells. It is found that hydrogen fuel cells dominate the market due to their high energy density and zero end-point emissions. However, their production process consumes high energy, and their instability imposes extremely high requirements on transportation and storage. Hydrogen fuel cells have indeed shown great potential in the field of environmental protection, but their commercialization process still faces some challenges. Fuel cell technology faces issues such as material stability and hydrogen leakage in practical applications. To promote the development of this technology, this article will start from analyzing the working mechanisms of different types of fuel cells and explore the future development prospects of materials.
