Grounding by Hydrogen Fuel Cell

Abstract

In this work, we will discuss fuel cells as an innovative source of energy, emphasizing their ability to directly convert the chemical energy of fuel into electricity through electrochemical processes. Unlike conventional methods, fuel cells achieve notable practical efficiencies, reaching up to 50%, and significantly reduce carbon dioxide emissions and other pollutants.

We will also emphasize the operation of fuel cells, their versatility in using various fuels, and their role in building a more sustainable energy future, with applications in vehicles and stationary generators. We will detail the manufacturing process of the fuel cell, focusing on bipolar plates, which represent more than 80% of the weight of the cell. The materials used, such as graphite and metallic compounds, are analyzed, highlighting the need to reduce costs to make fuel cells more commercially competitive.

Next, we will address the membrane electrode assembly (MEA), an expensive part of the cell that uses catalysts such as platinum. Strategies to reduce costs, such as the use of alternative polymers and optimization of catalyst dispersion, are explored.

Furthermore, a generator developed from fuel cells is presented, and procedures for grounding and hydrogen supply are detailed. The generator stands out for its efficiency, durability, and ability to operate in extreme conditions.

In general, the text provides a comprehensive overview of fuel cells, from their operation and manufacturing to their application in generators, highlighting their potential in transitioning towards a more environmentally friendly energy matrix.
