Energy sustainability: Use of hydrogen as a clean fuel in power generation

Abstract

In this work, a discussion is carried out about the generation of electrical energy through alternative sources that use hydrogen as fuel. The proton exchange membrane fuel cells are the most popular, which generate electrical power through an electrochemical process, where hydrogen molecules are subdivided into protons and electrons. Electrons circulate through conductors; thus, an electric current is generated. Furthermore, this process is friendly to the environment because the only waste generated is water and water vapor. Therefore, the fuel cells can be classified among clean energy sources; furthermore, depending on the technique used in hydrogen production, fuel cells could also be classified as renewable energy sources. Consequently, energy sustainability is achieved since a balance between the environment and the use of natural resources is guaranteed.
