The world in its run for progress and mechanization has almost exhausted all non-renewable energy sources that Mother Earth had provided. Global warming, depleted water sources, and increased pollution have caused a serious threat to the well-being of mankind. We are now looking desperately for renewable energies and alternate fuel. In our trust, the latest addition is fuel cells. Developed as a part of the space program initially, more and more car manufacturers are now edging towards adopting Hydrogen Fuel Cells to power the cars.
What are Hydrogen Fuel Cells?
The hydrogen fuel cell is same as our battery cells except for the fact that in the case of fuel cells the power is produced only when hydrogen is fed into the fuel cell. The electricity generated in hydrogen fuel cell is dependent on the rate of Hydrogen flow to the cell and also on the size of the fuel cell.
What are the applications of Fuel Cells?
Although along with electricity it produces heat and water, the fuel cells produce a lot less heat than the traditional rod cells. Hydrogen fuel cells are more efficient than the gasoline engines by about 20 to 30%.
These cells can be created in different sizes and as a result, can be utilized to power smaller instruments like an MP3 player to factory buildings and towns.
For the automobile industries, the biggest challenge today are its dependence on gasoline and the rate of pollution. Fuel cells if used as internal combustion engines for cars can reduce the petroleum dependency and environmental pollution.
Not just for cars, fuel cells used to power remote areas, provide electricity where roads have not yet been built and, in general, alleviate the living conditions. It can additionally use as a portable source of energy.
It is estimated that hydrogen fuel cells may replace the traditional batteries all together in the next 50 to 100 years. If it has been successful in the space programs, it is quite evident that it will leave its mark in day-to-day life as well. Different government and environment agencies are also supporting the use of fuel cells. However with all boons comes its accompanying bane. To produce hydrogen we need energy. Fossil fuels are widely used to generate that energy. Now as we all know fossil fuel too is a non-renewable energy source. So the need of the hour is a lot more research so that we can get hydrogen from a renewable power source to power hydrogen fuel cells in generating electricity.
We are very nearly a hydrogen revolution, a recent and likely last energy regime of humankind. Generating hydrogen with renewable power and utilizing it in fuel cell motor cars holds the promise of virtually sans pollution transporting and unreliability from imported fossil fuels and petroleum.
However there is no denying the fact that today we need such energy alternatives like hydrogen fuel cells that are customizable, can be used everywhere, can power anything from a small walkman to a town and the best of all reduces pollution and generated less heat. As we all know, it is a time that we do away with global warming!
