The Benefits of Fuel Cells as a Source of Energy The purpose of this paper is to inform you why fuel cells are a good source of energy. In principle a fuel cell operates like a battery. Unlike batteries fuel cells don't run down or require recharging. In the first section the energy source will be defined and described. The three sub-sections are; how they work, current us, and the future of fuel cells. In the second section the two criteria chosen will be defined. The two criteria are environmental friendliness and reliability. In the third and final section the two chosen criteria will be applied to the energy source. To understand fuel cells you need to know how they work. You also need to know the current use and development. Although no 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 energy source. Fuel cells are environmentally friendly because their only waste product is water. Reliability is also a good piece of criterion to use when evaluating an energy source. Fuel cells are reliable because they run on hydrogen and we will have hydrogen forever. What would the world be like without electricity? If you really think about it you will find that many of the everyday things we do would be impossible. You would not be able to eat many foods without cooking them over some kind of flame. You would have absolutely no luxuries such as TVs, computers, cars, and many other things that use electricity. This could be reality someday if something is not done to find an alternative to our traditional methods of burning coal and oil. Someday these resources will run ... ... middle of paper ... ...r air to breathe. We also wouldn't have to worry about oil tankers spilling millions of gallons of oil in the oceans, causing harm and death to millions of ocean plants and fish. If we take care of the earth now, we will have more natural resources such as trees, water, and animals, later. If we find ways to conserve oil and coal now we will be able to ration it out for a very long time but if we don't find alternative methods of getting energy we will run out of these highly consumed resources.

One type of engine is a called a fuel cell. A fuel cell operates like a battery. Unlike a battery, a fuel cell does not run down or require recharging. It will produce energy in the form of electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes sandwiched around and electrolyte. Oxygen passes over one electrode and hydrogen over the other, generating electricity, water and heat. Hydrogen fuel is used to make all this work. Fuel cell emissions are nothing but water vapor.

Because it is the most highly publicized of the different forms of ocean pollution, oil spills, oil leakages, and general oil contamination are something that we all seem to be aware of. Since the Exxon Valdez incident, the American public in particular has been more and more critical of oil companies.Each year, over 700 million gallons of oil end up in the ocean. Contrary to what you may have thought, most oil pollution doesn't come from tanker accidents. In fact, tanker accidents account for less than 90 million of the g...
We depend on energy; nothing in our daily lives could be possible without it. Electricity primarily comes from burning fossil fuels or using nuclear reactors. But the plain truth is, we are running out of fossil fuels. Our known oil deposits will run out in approximately 35 years, and if we increase the use of natural gas and coal to make up for the energy loss, our natural gas will last for 45 years and coal deposits will deplete in 75 years.
A microbial fuel cell (MFC) or biological fuel cell is a bio-electrochemical system that drives a current by using bacteria, and mimicking bacterial interactions found in nature. (2)

...iest thing, human urine. It kind of makes sense. It’s easy to get and really cheap to make. It’s actually very inventive.one I never will understand is the BMW that runs on human poop.(www.alternative-energy-news.info) That’s a little too far if you ask me, but again it’s easy to find and really cheap to make and easy to produce. In fact they are focusing on a lot of fuel to come from waste. Whether it be from humans, animals, plants, or anything else in the environment. Thinking about it alternate energy will help us immensely in the long run, despite the costs. That’s only the beginning. After all the spending and installing we will save a lot more after than before.
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
Prevent dangerous climate change by phasing out fossil fuels (oil, coal, gas) and replacing them with clean renewable energy such as solar.
... emissions and protect our natural resources, before we look to make a profit. Because once the natural resources and ozone are destroyed and gone, they are gone forever.
Solar power for instance is one of the most popular and easiest of all of the renewable energy sources to harness, especially for home and business uses. (Galbraith) For around the same ...
...rmined to be environmentally friendly and are able to pay for hundreds of dollars of hydrogen fuel, then you should just buy a regular car or a hybrid vehicle that runs on gasoline. Therefore, because of the lack of readily available hydrogen fuel and the inefficient methods of producing hydrogen in a clean way, the use of fuel cell cars is highly improbable for now. However, if we are able to create apt methods of producing hydrogen without the aid of fossil fuels, we could enter an age of hydrogen within decades.
In this day in age most people are living in an ultra modern world, we are depending on electricity for our everyday lives becoming a basic necessity. We have come so adapted to this way of living if one day we did not have electricity we would become lost and have difficulty with our everyday lives. So how would a life of an average person change? Now we can’t think life without electricity. We may think it might be easy but we truly depend on electricity everyday.
...outcompete fossil fuels, but by using different forms of alternative energy fossil fuels use could be reduced drastically. Now is the time for a conversion from fossil fuels to alternative energy.
