Fuels cells do not actually store electricity. They generate it instead, using hydrogen and oxygen as 'fuel'. The oxygen is atmospheric, the hydrogen must be stored under pressure and delivered to the cell through piping. So it's hydrogen that is being 'stored', not electricity as in a battery.
Inside the fuel cell, atoms of hydrogen and oxygen combine into water across a special membrane which produces electricity from the resulting energy of chemical combination of the atoms.
The "exhaust" of a fuel cell is therefore pure water, making them very 'green' to operate. The problem is producing hydrogen is a green manner - much harder to do, unless you're a plant with chlorophyll that can do photosynthesis using sunlight, the ultimate green technology.
Another problem is storing and distributing hydrogen gas under pressure. It is very dangerous in some ways, remember the Hindenburg!

How does a fuel cell power a car?
it squirts hydrogen throgh a fuel cell to make electricity to power the car
What is the main difference between a fuel cell and a voltaic cell?
A fuel cell generates electricity from a chemical reaction between a fuel source and an oxidizing agent, without requiring any recharging. A voltaic cell is a device that generates electricity from a spontaneous chemical reaction between two different metals or materials, which eventually stops producing electricity as the reactants are consumed.
What is the by-product of a fuel cell?
The by-product of a fuel cell is typically water vapor. This is because fuel cells generate electricity through a chemical reaction between hydrogen and oxygen, producing electricity, heat, and water as a result.
Fuel-cell automobiles use gas as a fuel?
No, fuel-cell automobiles do not use gas as a fuel. They use hydrogen gas as a fuel source, which is converted into electricity to power the vehicle.
What is a fule cell?
A fuel cell is a device that converts chemical energy from a fuel into electricity through an electrochemical reaction. It typically consists of an anode, a cathode, and an electrolyte. Fuel cells are used in various applications, including powering vehicles and providing electricity for buildings.
Is a fuel cell a secondary cell?
No, a fuel cell is not considered a secondary cell. Fuel cells generate electricity through a chemical reaction involving a fuel source and an oxidizing agent, without the need for recharging like secondary cells, such as batteries.
How would one describe a fuel cell car?
A fuel cell car would be defined as a vehicle with an electric motor or engine that uses a fuel cell to produce electricity to power its motor with hydrogen.
What is the difference between battery and fuel cell?
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.
How does hydrogen fuel cell differ from electrochemical cell?
A hydrogen fuel cell is a type of electrochemical cell that produces electricity by combining hydrogen and oxygen to generate power. The key difference is that in a hydrogen fuel cell, the reactants (hydrogen and oxygen) are continuously supplied externally to sustain the electricity generation process, while in a typical electrochemical cell, the reactants are contained within the cell and eventually get depleted.
What is the definition of fuel cell?
A fuel cell is an electrochemical device that converts chemical energy from a fuel, typically hydrogen, and an oxidant, usually oxygen, into electricity through a chemical reaction. Unlike batteries, which store energy, fuel cells generate electricity continuously as long as fuel is supplied. They are known for their high efficiency and low emissions, making them a promising technology for clean energy applications. Fuel cells are used in various applications, including vehicles, stationary power generation, and portable power devices.
What a fuel cell is why is it useful in spacecraft?
A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction. It is useful in spacecraft because it provides a reliable and efficient way to generate power in space without the need for combustion. Fuel cells have high energy density, are lightweight, and produce clean electricity, making them ideal for use in space where reliability and efficiency are crucial.
