Introduction

Hydrogen Fuel Cells Are They Really The Answer? By: Samah Syed Course Code: SCH4Ub Date: October 28, 2009 Hydrogen is one of the simplest however most prominent element in the universe. Containing only one proton and one electron, the hydrogen element is combined majority of the time with other elements. By having zero to zero gas emissions and by being an energy carrier; hydrogen is the next eco-friendly step on this planet. Since hydrogen-fuel cells contain a high energy and creating almost no pollution, these fuel-cells will contribute to our planet socioeconomically and environmentally. By using hydrogen-fuel cells in our cars; the internal combustion engine in cars which are very inefficient will slowly decrease and fade out of the economy. Hydrogen fuel cells are very attractive to cars because of their efficiency and the fact that they use water vapour instead of carbon dioxide. Hydrogen fuel cells contain two electrodes (anode and a cathode) similar to a battery and produces electricity while the reactants are supplied continuously from an external source. ...read more.

By having an unlimited fuel supply that doesn't contribute to smog formation or to the greenhouse effect will overall, decrease the quantity of pollution let out into the air and destroying our ozone layer. Hydrogen-fuel cells will contribute to the environment in a positive aspect because it can be produced by electrolysis, extract from gases such as fossil fuels or using renewable (hydro, wind, solar, nuclear) sources. By burning more hydrogen content then carbon dioxide, the air will become cleaner because less water vapour and carbon dioxide will be produced, therefore creating less greenhouse gas emissions. Hydrogen-fuel cells are versatile due to the fact that they can be produced from a number or renewable and non-renewable sources. Another environmental factor is that these cells produce water and heat as by-products however isn't a by-product for pollution, therefore doesn't contribute in depleting the ozone layer. Since, hydrogen-fuel cells contribute to the environment in a positive aspect, hydrogen-fuel cells should be used more often in vehicles. ...read more.

Conclusion

Hydrogen will play a major role socioeconomically because it can be transported such as electricity to different locations however not being used all at once because of the fact that it can be stored for later use. Hydrogen-fuel cells are the cleanest way of burning fuels and inevitably find alternative catalysts from base metals to make the hydrogen-fuel cells cheaper so consumers can buy this product and help the environment in an eco-friendly way. Hydrogen-fuel cells contribute to our planet socioeconomically and environmentally because of its high efficiency and being used to produce heat and electricity. By proving that it is more efficient than an internal combustion engine, hydrogen-fuel cells have attracted consumers and manufacturers to go greener and to create more hydrogen-fuel cells because it makes a significant contribution in reducing atmospheric emissions. Hydrogen-fuel cells will help contribute to our planet because they have fulfilled the requirements of being a cleaner and more efficient source and still being a friendly source of power. Therefore, hydrogen-fuel cells being an energy carrier and having zero to zero gas emissions; hydrogen-fuel cells is the next step into going greener and prospering our economy. ...read more.
