Fuel cells are reliable because they run on hydrogen and we will have hydrogenforever. By never running out of hydrogen fuel cells are the perfect energy source. Fuelcells are very reliable because they will always have fuel to run on. Fuel cells are veryreliable because they have no moving parts, which decreases the chances of parts breaking. In cars, fuel cells can go 280 miles without refueling. This shows their reliability becausethey can go a long way without having to worry about refueling. The less fueling youhave to do makes the car more reliable.This shows why fuel cells are environmentally friendly and reliable. Conclusion. Fuel cells are a good energy source because they are environmentally friendly andreliable despite being expensive. You might be saying to yourself " So what?". If wedon't find an energy source that we can use in the future when we run out of coal to burn. One day one of our most treasured luxuries, electricity, could be gone if we don't developa new way to produce it. Fuel cells are the perfect source from which to produceelectricity because they will always run when there is fuel, they don't pollute, they have nomoving parts, they don't make noise, and they are built to last twenty years. Fuel cellspower plants have an efficiency rate of 80 percent. They are twice as efficient as a typicaloil or coal fired plant. If we keep the planet free of destructive exhaust fumes, whichcause ozone depletion, we would have cleaner air to breathe. We also wouldn't have toworry about oil tankers spilling millions of gallons of oil in the oceans, causing harm anddeath to millions of ocean plants and fish. If we take care of the earth now, we will havemore natural resources such as trees, water, and animals, later. If we find ways toconserve oil and coal now we will be able to ration it out for a very long time but if wedon't find alternative methods of getting energy we will run out of these highly consume...
