Fuel cell technology: advantages and disadvantages scienceprog 10 march, 2009 10 march, 2009 technology in this age of technology, there is a development in each and every minute in almost all the fields is one regard or the other. Fuel efficient cars sale , fuel cell java , fuel cell animated gif , commercial hydrogen fuel cell , hydrogen fuel cars , hydrogen fuel cell design , make hydrogen fuel cell , balance sheet audit advantages and disadvantages , write an essay on the advantages and disadvantages of big families versus small ones , advantages and disadvantages of. According to future cars, advantages of hydrogen fuel cells include non-corrosion, water vapor emissions and an indefinite fuel source one disadvantage is the excessive carbon dioxide emissions when making hydrogen fuel cells another is the fact that replacing fossil fuel infrastructure with fuel. Products from oil fuels - hydrogen fuel cell what is a fuel cell a fuel cell is not the same as a battery a fuel cell needs to be continuously supplied with both a fuel and oxygen, which react together and produce electricity. Hydrogen fuel cells are a mechanical device that convert the electrochemical energy found in a fuel source, like hydrogen, into electrical energy, with the only byproducts being heat and water (hoffmann 6.
Fuel cells have various advantages compared to conventional power sources, such as internal combustion engines or batteries although some of the fuel cells' attributes are only valid for some applications, most advantages are more general. A hydrogen fuel cell has certain advantages over its alternative, a pure battery vehicle a battery carries only so much charge and as such has a limited range it is important to clear up any confusion with terms related to energy efficient vehicles. Important facts about hydrogen fuel cells nasa is the most famous supporter of hydrogen fuel cells, this is because they use them to power their rockets the united states has produced 198 billion pounds of hydrogen, this is enough hydrogen to power 20-30 million cars.
This informative paper about the use of hydrogen fuel cells in automobiles will examine a few of the advantages and problems of hydrogen fuel cells the writing is directed towards a technical writing professor with at least a little background knowledge on the subject. Hydrogen is the basic fuel, but fuel cells also require oxygen one great appeal of fuel cells is that they generate electricity with very little pollution—much of the hydrogen and oxygen used in generating electricity ultimately combine to form a harmless by-product, namely water. A hydrogen fuel cell in a car produces zero emissions the only substances released through its tailpipe are water vapor and heat producing hydrogen fuel cells doesn't release pollution either, provided that renewable sources such as water or solar energy are used in the production process. Disadvantages: hydrogen is a gas which can be compressed and stored in cylinders one of the major problems is the fuel tanks hydrogen is compressed which will contain less energy compared to liquid fuels. Durability: membranes that are part of the hydrogen fuel cell has to stand 100 degrees celsius and still function at sub-zero temperatures currently membranes tend to degrade while fuel cells cycle on and off, particularly as operating temperatures rise.
Hydrogen fuel cell vehicles represent the future of the automobile and will eventually surpass electric vehicles in sales, according to a washington-based research firm. Advantages: more detailed information is available in the applications section, which offers information specific to each industry high efficiency- when utilizing co-generation, fuel cells can attain over 80% energy efficiency. A fuel cell integrates hydrogen with oxygen from the air in a chemical reaction, producing electricity 7 one of the fuel cell types is for transport, (the proton exchange membrane fuel cell and it consists of two electrodes, and it is separated by a membrane.
Fuel cells have been the next best clean-energy thing for, well, a long time a bloom energy fuel cell at caltech credit: bloom energy a technology with roots in the 1800s and modern-day use in every nasa-manned space flight from apollo through the end of the space shuttle program, fuel cells just kind of look like a big box. As such hydrogen has an important role in the future as a replacement for imported petroleum, used currently in cars and trucks, but it has the following disadvantages : 1) although hydrogen cells are being used to power hybrid cars, it's still not a feasible source of fuel for everyone. A brief look at the pros and cons of hydrogen powered cars sources: . See the department of energy hydrogen and fuel cells office plan for plans and projections for the future of hydrogen and fuel cells more information learn more about the benefits of hydrogen from the hydrogen and fuel cells interagency working group and the fuel cell technologies office.
Advantages hydrogen and oxygen react to produce water, which isn't a pollutant so doesn't effect climate change it is a clean reaction hydrogen is made from water which is a plentiful resource and this therefore means that it won't run out for a long time. Before you consider using hydrogen fuel cells, it is important that you weigh the advantages and disadvantages advanced technologies can be of great help in developing sustainable, flexible, portable, and efficient alternative sources of energy. A fuel cell is an electrochemical device that produces electricity without combustion by combining hydrogen and oxygen to produce water and heat.
