Scientists are reporting development of a fuel cell that uses pollution from coal and metal mines to generate electricity, solving a serious environmental problem while providing a new source of energy. They describe successful tests of a laboratory-scale version of the device in a new study. So from here we can conclude that fuel cells are environment friendly device as it converts coal and other metal pollution into useful electricity.

The exhaust of the fuel cell is water molecule as hydrogen and oxygen molecule combine during process and concludes to water molecule. Depending on the weather conditions produced steam may rise and form clouds around the road, or it may form fog at the road surface, or it may condense and drop on the road. Even in warm weather water on the road will be dangerous. In freezing weather it will make the road downright treacherous, especially if most or all vehicles on the road are powered by hydrogen fuel cells.

The only problem occurs so far is the generation of large amount of heat as the motor vehicle working on fuel cell technology emitting more heat than other vehicles do. So this is the issue to be debate upon as in next decades the percentage of these vehicles increases leads to increase the temperature of the surroundings and then that of the earth atmosphere but one is for sure that is technology, right now, is in its earlier stage and in near future this problem will be over come by the Engineers.

But with the passage of time the problems will come and then will be overcome as this field is continuously in progress and will lead to great inventions as well as comes up with new facts and discoveries. Fuel cell technology is now applied in automobiles sector like new water car is manufactured and trains are going to crawl on this technology in future. We very well know that most of pollution is been caused by automobiles and if these are working on fuel cell technology then how much amount of carbon dioxide can be removed for atmosphere leads to obsolete the effects of Global Warming.

So now to conclude, for global warming the key ingredients are carbon dioxide and methane and both are not involved in this fuel cell technology as the waste comes out is water molecule and we all know that water is essential for living and that’s why never pollutes the environment. So fuel cell makes no pollution except one that is the generation of excessive heat energy by the automobiles and so it adds little (but that too can be manage) to global warming.
