Technical Status and Prospect of Hydrogen Fuel Cell

Abstract

The use of non-renewable energy leads to frequent ecological and climate problems, and the exploitation and utilization of clean energy has become the general trend of energy transformation and development in various countries. This article introduces the hydrogen fuel cell technology, its advantages and disadvantages, and its applications, and finally discusses the innovation and challenges. Firstly, this paper introduces the working principle of hydrogen fuel cell. Hydrogen fuel cells use hydrogen and oxygen to undergo Reduction-oxidation (REDOX) reactions under the action of a catalyst to produce electricity and water. The process is both efficient and emission-free, making it an ideal way to convert clean energy. Secondly, the composition of hydrogen fuel cell is introduced in this paper. Hydrogen fuel cell consists of hydrogen supply system, oxygen supply system, electrolyte membrane, anode, cathode and other components. The components work together to achieve the storage, delivery and reaction of hydrogen gas with oxygen into electricity. Then, this paper analyzes the advantages of hydrogen fuel cells. Compared with traditional internal combustion engines, hydrogen fuel cells have the advantages of zero emissions, high energy conversion efficiency, and fast charging. Additionally, hydrogen fuel cells are not subject to geographical restrictions, and can be flexibly applied to various transportation and energy fields. Finally, the application prospect of hydrogen fuel cell is prospected. Hydrogen fuel cells have been widely used in automobiles, public transportation, ships and aircraft, and remarkable results have been made. In the future, with the constant progress of technology and the decline of costs, hydrogen fuel cells will be further popularized and promoted, becoming an important part of the field of clean energy and making important contributions to the realization of sustainable development. In the future, if the market strengthens the top-level planning of hydrogen energy development, improves hydrogen production technology, speeds up component research, and improves metallurgical technology, hydrogen energy is expected to be greatly utilized. This paper provides a theoretical basis for hydrogen fuel cell research, and provides suggestions and measures for large-scale commercial use of hydrogen energy.
