A fuel cell generates electricity through an electrochemical reaction between hydrogen and oxygen. In this process, hydrogen gas is fed into the anode side of the cell, where it splits into protons and electrons. The protons pass through an electrolyte membrane to the cathode side, while the electrons travel through an external circuit, generating an electric current. At the cathode, the protons and electrons recombine with oxygen to produce water and heat as byproducts.

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 is nuclear energy delivered to you explain?
as electricity. If hydrogen fuel cell cars make it may be delivered at your filling station as liquid hydrogen.
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 gas for fuel-cell cars is not readily available in pure form?
I expect you are thinking of hydrogen. It's not that we don't have plenty of ways to make it, indeed we do that, in vast quantities, to manufacture fertilizers, margarine etc. The problem is that we make it from natural gas, a fossil fuel, and there's no point to the fuel cell if it doesn't replace fossil fuel use. We can also make hydrogen by electrolysis, but that requires electricity, and therefore a way of making electricity, so doing that without burning fossil fuels becomes the issue.
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.
