Fuel cells are a form of clean, sustainable technology. A hydrogen fuel cell could be the utmost substitute for traditional fuels like gasoline, diesel and natural gas. This essay will describe the operation of fuel cells, the relationship with hydrogen fuel cell vehicles and possible drawbacks of using them.

What Are Hydrogen Fuel Cells? Hydrogen fuel cells produce electric power in a clean and economically efficient manner. The chemical energy that is utilized to produce in a reaction between hydrogen and oxygen to produce water vapour and fuel cells. Due to the absence of any evaporated pollutants such as carbon dioxide Fuel cells are emissions-free and environmentally friendly. Their ability to supply the energy needed for all types of devices, ranging from portable ones to massive power plants, makes them economical and widely adaptable. Hydrogen-based fuel cells are superior to combustion-based technologies in terms of efficiency and environmental pollutants. The combustion-based systems are known to release copious amounts of carbon dioxide along with numerous harmful toxins. In contrast, the hydrogen fuel cells are characterized by the absence of evaporated pollutants. In addition to this, the operational quietness of the fuel cells, which stems from the fact that the devices have fewer moving parts than a combustion, makes them ideal for a number of uses.

As per GMI Research, the Fuel Cells Market is forecast to reach USD 21.9 billion in 2030

Operational Procedure of Hydrogen Fuel Cells

As with any fuel cell, the major elements of a hydrogen fuel cell are hydrogen and oxygen, the reaction of which produces water as the reaction’s by-product. The by-product of this reaction, water, does not lead, any pollution. This means that there is a complete absence of pollution from the fuel cell. The center of any fuel cell is still a stack of individual cells, with each cell comprising of two electrodes, one positive and one negative, which sandwich an electrolyte. Hydrogen enters the fuel cell from, one side, while oxygen enters from the other side.

As the gases pass the anode and the cathode, oxygen is dissociated into negatively charged electrons and positively charged protons. The electrons and protons are free to move, with the separator, the electrolyte, allowing these charged particles to pass to the anode. The external electrical current is supplied with these charged particles flowing from the anode and cathode.

In order to achieve the purpose intended for them, the individual fuel cell needs to be arranged in stacks to generate sufficient energy. This means the fuel cell alone would most likely not aim to generate a significant amount of electricity. Hence, they would need to be arranged in stacks otherwise the amount of energy produced would be insufficient.

Among the several different fuel cell systems that exist, there are also hydrocarbons such natural gas, biogas, and even methanol. Fuel cells are different from most electricity producing systems in the sense that they do not rely on burning fuel. Instead, there is an electrochemical reaction that takes place within the fuel cells. This is more efficient than most systems of energy production.

Cars that use hydrogen as fuel are becoming increasingly banned for sale and use in most countries and are therefore more popular for eco friendly drivers who wish to conserve the environment. In comparison to burning fuel cars, fuel cell cars are better in almost every aspect. However, there are still several factors that need to be addressed. Most people still do not have easy access to hydrogen fuel cells and so do internal burning cars. This is a reason as to why they are banned, as the prices for fuel cell cars and the stations are not affordable.

Versatile and greatly efficient, sophisticated Fuel Cell Technology quiets a myriad devices and, in the process, offes invaluable assistance in solving the paradox of the fossil fuels and the focus around them, which has been for years. Although the use of such techniques have been in existence for a century and a half, only recently has it become a common substitute for energy technologies due to the increased focus on and improvement in ease of use and cost reduction.
