Fuel Cells

Parent Category: Electrical Engineering
Fuel Cells convert an electrochemical reaction to electticity. There are applications that are sationary, portable and those used in transportation. All Fuel Cells are composed of an anode, cathode and electrolyte and are typically characterized by the composition of he electrolyte. The most common is the Proton Exchange Membrane (PEM). Others are Phospheric Acid (PAFC), Solid Oxide (SOFC), Molten Carbonate (MCFC) and Direct Methane (DMFC).
cant learn every individual move of the system but i know what the  fuel cell will be good for
Hydrogen fuel cells are very similar to batteries. They use a chemical reaction between atoms to produce their energy.   •It has two electrodes, an anode and a cathode, separated by a membrane. Oxygen passes over one electrode and hydrogen over the other.
There are 3 main types of a Fuel Cell.1. Hydrogen Fuel Cell. This is the main one people use nowadays.2. Solid Oxide Fuel Cell.3. Alkaline Fuel cell. Made from Alkaline metals.
Hydrogen fuel cell cars are simply electric cars with a different kind of battery.   The hydrogen that is stored in a tank runs to the (in this example case) Proton Exchange Membrane, where the hydrogen nucleus, a proton, passes through the membrane, while the electrons must stay behind.   To...
One company commercially offers fuel cell power plants for about $3,000 per kilowatt.
if you want exat procedures theres 3 different ways that i have found. They're all on the same website and here is the exact web address for all 3The first one is http://www.instructables.com/id/Simple-Algae-Home-CO2-Scrubber-Part-III-An-Algae/The second is http://www.instructables.com/id/Make-a...
They use the wrong kind of energy and they use too much of it. That's why other batteries are way better. One, they hardly use 6% as much as chemical fuel cells. Two, the chemical fuel cells pollute the air too.
A problem with fuel cell cars is that hydrogen is not readily available in pure form
Hydrogen Fuel Cell converts the thermal energy released directly into electrical energy.. This fuel cell was used in the Apollo Programe. It also produces water.....
They can, but so far it's so much easier to use traditional fuels  that it's just not worth it.
Possibly. Hydrogen car cost more then hybrid cars. But as of today, those cars are possibly in development.
One of the biggest precautions that needs to be taken when you fix the water fuel cell in cars is to protect yourself against electrocution. This involves using the appropriate safety equipment, such as insulating shoes and gloves.
It explodes because of the high Energy and because it has a lot of isotopes and and if you put some Einsteinium in it, it will destroy a planet the size of Jupiter
Anything that needs electricity can be fed from a fuel cell.Power vehicles
The most important advantage of fuel cells is that their only byproduct is water, and of course discarded parts. The disadvantage is that the hydrogen used in them has to be electrolyzed from water or found in some other way. Because of the law of conservation of energy, fuel cells do not produce...
  Fuel cells are basically a storage device for energy. In the cars on the road today they are gasoline tanks. In hybrid cars, they are gasoline tanks and batterys. In GM's Hydrogen car, the fuel cell is the Hydrogen tank.
here are several innovations that have been declassified, patented, and sold. Here is a list of those innovations, all are either required or otherwise set as a standard for legitimate automotive use.HHO dry cell - uses electrolysis to turn water to hydrogen and oxygen very efficiently.computer...
Proton Exchange Membrane Fuel Cells are used for both stationary and portable applications. Advantages such as high current densities, fast start-up times and compactness of design makes this type of fuel cell a very attractive and promising candidate for automotive and portable applications.
Fuel conversion cells are made from platinum and convert the material going through the device into heat and electric power (about equally). The element used is often hydrogen. Hydrogen comes from many places, but the practical commercially viable method in use is from stripping all other elements...
They wouldn't know really know because hydrogen fuel cells isn't your ordinary sit-around-the-dinner-table conversation. Me, quite frankly, feel that it may be our future. One day when we get tired of using gasoline, hydrogen fuel cells will be the future!
A 91 what and a 93 what?
Anyone can do it, but the problem is doing it efficiently enough so that it competes with the price of Oil.     1. Grow some algae in a vat using photosynthesis to turn CO2 and sunlight into sugar.    2. Dump out the algae into a filter, collect the sugars.    3. Feed the sugar...
\nThey are too expensive and are hard to find.
Neither car is available and most likely will not be for some time, if ever. Fuel cell technology is probably closer to a reality. The major disadvantage is that they produce no fuel savings and are not a positive for our environment. Hydrogen is derived by stripping it from natural gas. The net...
a fuel cell is a cell that produces electricitythey are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells
no, they just mean that the engine has a supply of hydrogen to run on rather than any other fuel
The most likely spot for a hydrogen fuel tank on any possible car that will be built is going to be on the top of the car. This would prevent you from becoming part of the fuel burn in an accident. The fuel would flow up and away from the people involved. They would not be any more dangerous...
explain how fuel cells are commonly categorized
yes it type of fuel
A fuel cell is different from a battery cell in so far as reactants are constantly supplied to a fuel cell making it an open system whereas a battery cell is a closed system that stores the reactants within it. A fuel cell works as long as fuel is supplied to it whereas a battery cell requires...
A hydrogen vehicle is an alternative fuel vehicle that uses hydrogen as its onboard fuel for motive power. The term may refer to a personal transportation vehicle, such as an automobile, or any other vehicle that uses hydrogen in a similar fashion, such as an aircraft. The power plants of such...
They are already!   Unfortunately vehicles developed and powered by fuel cells are  technologically problem prone, but some significant progress has  been made already. Although cost prohibitive; eventually the  consumers own demand coupled with the high cost of fossil fuels  (and...
Well you have to get the owl, go down to the dungeon cell, and the alien will self destruct. You will see the green tube go out of the cell, where you cant reach it. So, click on the owl then the green tube, the owl will get it for you and now you have the green tube! Hope it helped! :D
The electrodes of a storage battery, particularly the lead - lead dioxide batteries commonly used in starting vehicles, may deteriorate because the discharge reaction requires one or both of the solid electrodes used to dissolve partially in the electrolyte, and the recharging reaction requires...
Hydrogen fuel cells powered the Apollo space craft of the 1960's. They're also used today as large power plants for rural areas
A fuel cell is an electrochemical energy conversion device whiles a solar cell is a device that converts photons from the sun into electricity.
There are currently no Fuel Cell vehicles being sold to the public. Only prototypes have been built.
Today they are used in cars
it is when u put the cookies in da soup and warm the soup up to roughly about 120 degrees so the cookies melt in the soup and long story short is that orange juice gives u the poots
More mass is converted to energy in a fusion reaction than in a  chemical reaction, such as that found in a fuel cell. - APEX
The fuel cell hydrogen is one of the two gasses, that are created by the seperations of a water molecule H2O. A water molecule consists of H - hydrogen, and O - oxygen. A fuel cell hydrogen is the gas created by the separation of a water molecule with the help of a fuel cell.
  == Answer ==   I'm no expert.... but... I crashed my car and part of the repair involved getting a new rear axle, afterward I noticed that filling the fuel tank took ages.... fuel would back up all the time.     I brought it to a garage for service, and mentioned the fuel issue, they...
In a normal hydrogen oxygen fuel cell, the waste products are water, and heat
A: All batteries will eventually fail when that occurs the voltage out of then can be zero or higher voltage when new, In that case the battery has failed but if you measure the output it will have a higher voltage because there is no load or open circuit as soon as the load is applied the voltage...
water which is an electrolyte in this case , or hydrogen in the water is used and burned
They're trying to, but so far they're still too complicated and  expensive for everything but very special applications.
It is much easier to control the hydrogenand oxygen during direct combustion thanduring their reaction in a fuel cell.
combustion of fuel needs O2 so hydrogen fuel cell's combustion formula is: 2 H2 + O2 --> 2 H2Othe product (waste) is water molecule
Work hard... This is the only solution...
Beyond their use of hydrogen to make power there are nothing but differences between the two. Fuel cells combine oxygen and hydrogen in a porous membrane to make electricity. Hydrogen fusion takes two hydrogen atoms and fuses them into a helium atom generating heat and several particles.
  because hydrogen is in the fuel cell.   hydrogen is useful in many things including spacecrafts.   please do not use this for anything important because I'm not sure but i been reading this page about hydrogen and it is true. I know for sure that hydrogen is used for rocket fuel because...
A fuel cell is really just a smaller gas tank, usually installed in drag/race cars, and off-road vehcles. Less fuel means less weight, thus increasing the power-to-weight ratio in a vehicle. It also makes more space in the undercarriage of the vehicle, allowing for installation of larger/different...
In innovative research area the Zn Zn2 pair is the most used. But in commercial distribution you find only the hydrogen fuel cell.
Water vapor is the sole byproduct of fuel cell electric vehicles.
    very silly question boy
The advantages of using hydrogen fuel cells are that they are an alternative fuel to fossil fuels, like coal, oil and gas. Also, burning or reacting hydrogen with oxygen runs electric motors and it's only emission is water vapour. The disadvantages of using hydrogen fuel cells is that hydrogen does...
the amount of mass that disappears in the fusion of two hydrogen atoms is morte than the amount of mass that dissappears when two atoms are fully used in a cell
There are no commercially available hydrogen fueled cars.
Vehicles can run on fuel cells and this has been demonstrated, but I don't think there have been any produced for general sale, probably they are too expensive to make. A vehicle takes a certain amount of energy to run, wherever the energy comes from. Of course if electric cars have low speeds and...
Probably, but the technology for ordinary day usage just isn't there yet. Nuclear power can be safe. We just need to think of all the possible scenario's that could happen. The Japanese built the nuclear plant to sustain an earthquake much larger (and it did), but they didn't see the fact that the...
There are many different types of cathode ray oscilloscopes. Some  of them are: analogue, digital storage, digital phosphor, and  sampling.
you have to defeat the sewer king then get into the sewer with the crowbar
Polymer Electrolyte Membrane (PEM) fuel cells used in  automobiles-also called Proton Exchange Membrane fuel cells-use  hydrogen fuel and oxygen from the air to produce electricity. The  diagram to the right shows how a PEM fuel cell works.    Most fuel cells designed for use in vehicles...
You use it to upgrade the flamethrower, which you have to make from a leaf blower, which you get from the hardware store, which is restricted to the Director's Cut.

You use it to upgrade the flame thrower.
In my opinion yes! i have a large face and i usually wear gascans but i recently purchased some Fuel cells the biggest difference is the side ear pieces are thicker on the fuel cells. I HOPE THIS HELPED
It may seem easy to create a hydrogen fuel cell generator, and there are many people who will tell you that it is an easy task; however, actually accomplishing this and making it work as you would like it a more complicated process than many would say. Many of the do-it-yourself plans for these...
A hydrogen fuel cell generator is quite simple in theory, but in construction it can be quite difficult. You need three airtight containers, preferably completely empty of everything, including air. Then you would need some elecrtodes, copper and zinc or nickle working well. These are just the...
Yes, many institution will provide incentives for any renewable energy and hydrogen is one of them. Check your state first then the federal government to see what your entitled to.
The bio fuel cell work on the principle of converting some chemical energy into electrical energy.
The Daniell cell (Daniel cell) was invented in 1836 by John Frederic Daniell, a British chemist and meteorologist, and consisted of a copper pot filled with a copper sulfate solution, in which was immersed an unglazed earthenware container filled with sulfuric acid and a zinc electrode. As such it...
The Fuel cell upgrades the flamethrower, for the flamethrower you need a leafblower and somethingelse
What author? What article? Please restate the question. It is lacking in information necessary to properly answer it.
The only thing that comes out of the tailpipe is water! The other not so remarkable thing is the price. A fuel cell is made up of two electrodes, and each one is an ion-transfer membrane (allows ions to pass through but not air or liquid). In between these membranes is a liquid called electrolyte,...
no because hydrogen fuel cells are renewable
You have to kill all the sewer people, the last person you kill will give you the fuel cell.
No. Hydrogen fuel cell is not a title. You would only capitalize hydrogen if it was at the beginning of a sentence, as I did with this one. Otherwise, you would say 'hydrogen fuel cell'.
it squirts hydrogen throgh a fuel cell to make electricity to power the car
