Ever since the process of industrialization has been set off more than a century ago, people have started to deal with serious problems regarding pollution and especially the greenhouse effect. These problems have started affecting the population everywhere and experts are still trying to find a solution regarding the improvement of this issue.
Nanotechnology has proven to be one of the most appropriate means to fight the emissions of gas in the world. Nanotechnology is the science dealing with materials that are constructed on very small scales, devices like molecules or individual atoms. This science deals with the structure of materials that are presented at a molecular level.

The technologies produced by fuel cells are regarded as real solutions for producing the necessary energy used in the fields of stationary power, automotive and portable equipment markets. In the past, fuel cells’ technology was not given the importance that it deserved because of the great costs required by the production and storing processes of hydrogen. Recently, scientists have started to pay more attention to fuel cells, as they have proved to produce no carbon dioxide that would fasten the harmful greenhouse effect. This started happening after California has promulgated the law that would strengthen the fight against greenhouse emissions.

The greenhouse effects are predicted to affect the atmosphere more and more in the future and their effects are increasingly harmful for earth’s atmosphere. This is the most important reason for the creation of the Californian law to reduce the emissions of gas worldwide. The main advantage of fuel cells is that they are made of clean hydrogen which is thought to be a benefic feature of these cells. They only produce pure water as exhaust. Even when they also use fuels that are fossils in nature, the pollution that they produce is a lot more insignificant than the one produced by conventional technologies. Releasing the energy in a combustion having high temperature (as in the example of the internal combustion engine) results when creating sulph oxides.

Fuel cells give a high quality power and are perfect for modern electrical equipments such as hospital equipment or sensitive electronics. National electrical grids, now-a-days suffer much from black outs, power fluctuations and brown outs, problem which will be avoided with the help of special energy network created of these fuel cells.

Right now fuel cells are not very cheap to use as energy sources. However it is predicted that they will offer a significant lowering of costs in contrast to the traditional energy solutions and this cost reduction is likely to come for the near future. The total energy of fuel cells is a lot higher than the other common energies, and not only that but there are also additional benefits and advantages conferred by them that can enable savings to be made in many domains, such as environmental stewardship and sustainable development.

Pure hydrogen is known as the perfect fuel to be used for fuel cells. Alas, hydrogen is highly reactive element. Also, it is a rare found element in its pure form. Hydrogen fuel can be produced from both renewable as well as traditional energy sources. Besides using hydrogen, it is also possible to run fuel cells on many other fuels, like for example, fossil and bio-fuels.

Fuel cells have proved a great efficiency and even greater versatility and a multi-fuel
capability features which permit the ease of usage of these molecular energy generators. The cars using fuel cells with hydrogen are very environmentally friendly, as they only emit water vapor and not polluting gases as common fuel cars do.

In conclusion, the benefits of fuel cells are numerous, among which we can count the national energy security, the much cleaner air, and last but not least the economic opportunity given to the world’s population.
