What are fuel cells?
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
Polymer electrolyte fuel cells (PEFCs) PhoMolten carbonate fuel cells (MCFCs) sphoric-acid fuel cells (PAFCs) Solid oxide fuel cells (SOFCs)
explain how fuel cells are commonly categorized
Ceramic Fuel Cells was created in 1992.
no because hydrogen fuel cells are renewable
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 converts chemical energy to eletrical power and the only waste product for fuel cells is water
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
The only byproduct of an oxygen and hydrogen fuel cell is water. There are other less common types of fuel cells, such as zinc and air cells, which do produce other byproducts.
Fuel cells are an important part of a nuclear reactor. The component that powers the nuclear reactor is the reactor core and the fuel cells are found inside and hold uranium dioxide.
Fuel cells in a nuclear reactor hold uranium dioxide, a concentrated form of power for the reactor. There are several hundred fuel cells which are held within the reactor core.

Yes. Mass producing cars is not the problem. The fuel for fuel cells is too expensive, so far.
Two reasons: Weight. Batteries are heavier per energy unit than fuel cells. Capacity. Fuel cells can store much more energy than batteries. As a bonus, the weight for the fuel cell fuel reduces the weight of another required consumable: water. The "exhaust" of fuel cells is pure water which astronauts can drink.
it gives us fuel
the fuel cells convert hydrogen into energy using a converter and that energy is used to power the vehicle
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
No, body cells cannot use hydrogen on its own as a fuel. It needs to be included in a carbohydrate such as sugar, protein or fats.

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 produce less than 1.16 volts of electricity-far from enough to power a vehicle. Therefore, multiple cells must be assembled into a fuel cell stack. The potential power generated by a… Read More

They all produce static electricity.
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.
More mass is converted to energy in a fusion reaction than in a chemical reaction, such as that found in a fuel cell. - APEX
Fuel cells are a manufactured item and are not renewable. The fuel that is used in the fuel cells can either be renewable (alcohol, methane from waste digestion,hydrogen from wind or solar conversion of water) or non-renewable (Hydrogen or methane from oil and gas production, alcohol from industrial processes)

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 energy, they only store it.
Yes. Fuel cells could viably power the entire car. For evidence, look at NASA's space shuttles. All are totally powered by fuel cells. Fuel cells have even been developed to power, heat, and provide pure drinking water for homes. They're currently expensive, but with increased demand, the price would natural come down.
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.
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!
yeast can be used to ferment starch, the result alcohol can be used as fuel
The C-5 has 12 fuel cells.
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
Cells do not choose their source of energy.
the job of fat cells is to store fat in the body until it is used for fuel
Starch is found in plant cells as glucose or fuel for the plants.
