Fuel Cells

As i said again u tell me wiki answers and to people who know everything screw u and remember Y.O.L.O including u Sean

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

Hydrogen fuel cells deteriorate over time, and must be repaired or replaced. The speed at which they deteriorate is of some concern, as it may take as little as a few years for them to fail.

Fuel cells and batteries are similar because they use a chemical reaction to provide electricity. A battery stores the chemical reactants, usually metal compounds like lithium, zinc or manganese. Once used up, you must recharge or throw away the battery. A fuel cell actually creates electricity through reactants (hydrogen and oxygen) stored externally. The fuel cell will produce electricity as long as it has a fuel supply. In short, a fuel cell vehicle is refueled instead of recharged.

There are currently no hydrogen powered cars commercially available. These cars would be far from green in any event because of the way we make hydrogen currently. Hydrogen is currently made by stripping hydrogen from natural gas and venting the rest of the material to the air.

Most hybrid cars run on diesel and electric. Typically the diesel engine provides the electricity for the electric motors which turn the wheels.

Alternatively some cars set off using a combustion engine, and then cruise using electric, until the vehicle comes to a steep slope to climb, at which point the combustion engine steps in to provide the necessary horse power to pull the vehicle.

Currently, no production autos use fuel cells.

The waste products from fuel cells are typically water and heat. In some cases, small amounts of carbon dioxide and other gases may also be produced depending on the type of fuel cell and the fuel used.

Hydrogen fuel cells produce electricity through a clean process, emitting only water vapor as a byproduct, which significantly reduces greenhouse gas emissions. However, the production of hydrogen often relies on fossil fuels, which can negate some environmental benefits. Additionally, hydrogen is highly flammable and requires extensive infrastructure for storage and distribution, posing safety and logistical challenges. Despite these drawbacks, hydrogen fuel cells offer high efficiency and potential for use in various applications, including transportation and stationary power generation.

water vapor

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 a proposed global energy system that is completely clean energy system. In this system, hydrogen is produced (parallel with electricity) from renewable (like solar) or non-conventional (like nuclear) primary energy source.

Fuel cells have typically used hydrogen and oxygen as a power source. You can get these gases by splitting water (H2O) either by electrolysis or by what we call water thermochemical decomposition. In this thermochemical decomposition method water can be split into hydrogen and oxygen in some consecutive intermediate steps where special chemicals are used as catalysts to get this decomposition possible at practical temperature ranges.

As an aside: For the same amount of energy, coal produces more greenhouse gases (CO2) than gasoline. So, if your electricity is generated form coal (which is common), a fuel cell powered or electric car will probably produce more greenhouse gases than a gasoline powered car (of the same size, power, etc).

Electric powered cars are considered environmentally friendly so far as the electricity is produced from a renewable or non-conventional primary energy source.

I believe you are asking about a fuel pump and fuel storage cell used to supply gasoline to an engine, perhaps in a car or other vehicle. If not, the answer below is wrong... The fuel pump can usually supply fuel at a much greater rate than the engine can use. In a carbureted engine, when the float bowl is full, the float and needle valve reduces fuel flow so as not to flood the engine. If the engine is idling or cruising with not much load, there is very little fuel flow to the carburetor. Most of the fuel just sits there in the line. If the temperature is high enough, like under the hood of a car sitting in traffic on a hot summer day, the stagnant fuel in the line can boil, causing vapor lock and a stalled engine. This is why we add a return line. Instead of just sitting there in the line, excess fuel flows through the bypass line back to the tank, where it mixes with the large volume of fuel in the tank, cooling it. The fuel circulating through the system never (hopefully) gets hot enough to cause problems. If the engine is fuel-injected instead, then the return line also serves another purpose. The pump sends fuel to the injector fuel rail, then the bypass line returns it to the tank. The fuel pressure regulator adjusts the amount of fuel returned through the return line to control the pressure in the fuel rail so the injectors have a constant pressure to operate from.

There are currently no Fuel Cell vehicles being sold to the public. Only prototypes have been built.

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.

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 get back to the hydrogen atoms, which are already mingling with oxygen atoms, the electrons pass around the membrane and are captured in an electrical circuit and forced to do work (like run a motor) before they can be reunited with the hydrogen and oxygen. once reunited, the resulting chemical is just hydrogen and oxygen; water.

Some pros of fuel cells are that it is: -efficient -produces no odor, no noise -reliable -environmentally friendly -is indefinetely renewable, as long as hydrogen is harvested Some cons of fuel cells are: - fuel cells are expensive -you have to harvest hydrogen, which is hard -The volume of the fuel cells are larger than the average internal combustion engine.

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

20 gallon tank even if you can only put in 15 gallon. remove vent tube and cut down for 5 more gallons.

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

These frivolous idiots should be euthanized for wasting the time of the rest of us.

i like cheese how about you ? I LIKE CERAL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i like chocolate milk......
