What is the Proper placement of a fuel cell?
cant learn every individual move of the system but i know what the fuel cell will be good for
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.
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 is more akin to a battery than a fuel cell.
Fuel cells come in many varieties. Low-temperature designs such as proton exchange membrane fuel cells [PEMFC's, also known as polymer electrolyte membrane fuel cells] are mostly aimed at portable and transport applications
Fuel cells are capable of converting fuel directly to electrical energy. All of the fuel cells currently in production are relatively expensive and considerably less than perfect, especially since they get so hot and waste electricity. There are a few different types of fuel cells. Some run on hydrogen, others on methane.Special gas tank used in race cars.A fuel cell refers to a cell producing electric current directly, this is usually from a chemical reaction.
Scientists are currently studying Hydrogen Fuel cells as an environmentally friendly option for the future. Although they are not as energy efficient as battery cells, the only emission they produce is H20, and as most of it will condense before it enters the atmosphere, it is not a threat. There are many pros and cons of this fuel cell - I recommend this website to help answer your questions further - http//environmentalenergy.com
What is the difference between Benthic Microbial Fuel Cell Microbial Fuel Cells Is there a difference?
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.
Today they are used in cars
Fuel cell vehicle is the vehicle which is using fuel cell stack as a moving force instead of conventional combustions engines. They can be fed by H2 - so it will hydrogen fuel cell, or work on the solid oxide fuel cell principles.We have published several article at our website http://fuelcellsinfo.comPlease check
water which is an electrolyte in this case , or hydrogen in the water is used and burned
Water is the benefit of a hydrogen fuel cell ;)
In a normal hydrogen oxygen fuel cell, the waste products are water, and heat
I am not able to give you a cost, as there are a number of fuel cell technologies, and it will be difficult to know which ones might ultimately become commercial. So far, fuel cells applications have required large government subsidies. The "hydrogen car" is still apparently a long ways from becoming a reality- see related links.
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 from natural gas. This means that the hydrogen used in most applications is a fossil fuel. This does not mean it must be this way though. Hydrogen could… Read More
Fuel cells operate by combining hydrogen and oxygen without actual combustion as in gasoline engines. A catalyst separates the electrons and protons to combine the elements. (Some versions of fuel cells are high-temperature only.) Hydrogen gas
No, it is not a renewable source of energy. Fuel cell is a means of storage energy, for example hydrogen can be produced from any primary energy source; renewable (as solar energy) or exhaustible (as coal or oil) and then stored as energy in the fuel cell. When energy is needed later on as electricity then we can get from the fuel cell. Fuel cells is very efficient as in intermediate energy storage system in… Read More
I think it is water pretty sure it is water :)
no because hydrogen fuel cells are renewable
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 drivetrain and suspension components.
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 energy, they only store it.
This reaction could be called either a synthesis reaction or a combustion reaction. The chemical equation is: 2H2(g) + O2(g) -> 2H2O(l)

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.
The purpose of that is to make less contamination in the wolrd.
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.....
Its byproduct is water.
A fuel cell is an electrochemical energy conversion device whiles a solar cell is a device that converts photons from the sun into electricity.
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 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, whose job is to carry ions from one electrode to the other. On the far side of the cathode (negatively… Read More
The bio fuel cell work on the principle of converting some chemical energy into electrical energy.
Acetate is simply the fuel or food for the bacteria. It is their carbon source and the electron donor.
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 just disappear this condition is called open circuit voltage
There are two problems with hydrogen fuel cells. One is that the cars that run off of hydrogen fuel cells are very expensive to make another thing is that hydrogen storage is not easy. The work and money it would take to put up hydrogen stations around the country for cars is too much to even consider it. Also another problem with hydrogen is te oil companies that don't wanna lose their business.
fuel cells are the hydrogen fuel cell that operates similar to a battery. It has two electrodes, an anode and a cathode, separated by a membrane.fuel cell is a type of an electro-chemical cell which can convert the fuel energy into electrical energy by reactions of oxidized and fuel particles triggered in the presence of electrolyte
combustion of fuel needs O2 so hydrogen fuel cell's combustion formula is: 2 H2 + O2 --> 2 H2Othe product (waste) is water molecule
A hydrogen fuel cell uses hydrogen as its fuel and oxygen (usually from air) as its oxidant. Other fuels include hydrocarbons and alcohols. Other oxidants include chlorine and chlorine dioxide.
20 gallon tank even if you can only put in 15 gallon. remove vent tube and cut down for 5 more gallons.
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.
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 it is on the sheet. By Georgina thank you 4 going on wikianswers.com
Its the source of energy. 'and it can even be used to generate electricity for spacecraft.'From Pearson Education Limited 2002
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 regular replacements.
