The purpose of this paper is to inform you why fuel cells are a good source of In principle a fuel cell operates like a battery. Unlike batteries fuel cells don'trun down or require recharging. In the first section the energy source will be definedand described. The three sub-sections are; how they work, current us, and the future offuel cells. In the second section the two criteria chosen will be defined. The two criteriaare environmental friendliness and reliability. In the third and final section the twochosen criteria will be applied to the energy source. To understand fuel cells you need toknow how they work. You also need to know the current use and development. Althoughno one can tell the future of fuel cells, you can tell what direction they are headed. Environmental friendliness is a good piece of criterion to use when analyzing an energysource. Fuel cells are environmentally friendly because their only waste product iswater. Reliability is also a good piece of criterion to use when evaluating an energysource. Fuel cells are reliable because they run on hydrogen and we will have hydrogenforever. Introduction.What would the world be like without electricity? If you really think about it youwill find that many of the everyday things we do would be impossible. You would not beable to eat many foods without cooking them over some kind of flame. You would haveabsolutely no luxuries such as TVs, computers, cars, and many other things that useelectricity. This could be reality someday if something is not done to find an alternative toour traditional methods of burning coal and oil. Someday these resources will run out andwe will be stuck without electricity. This is why we should invest our time, money, andresearch into the production of fuel cells. Fuel cells are a good energy source becausethey are environmentally friendly and reliable despite being expensive. In principle a fuel cell operate like a batter...
