For a fuel cell to produce electricity, it requires a fuel source (commonly hydrogen) and an oxidant (typically oxygen from the air). The fuel undergoes an electrochemical reaction at the anode, releasing electrons, while the oxidant receives these electrons at the cathode. This flow of electrons generates an electric current, while the reaction also produces water and heat as byproducts. Proper management of these inputs and outputs is essential for efficient operation.

How do you put hydrogen in a fuel cell?
Hydrogen is typically stored in a compressed or liquid form and then fed into a fuel cell. The hydrogen reacts with the electrolyte in the fuel cell to produce electricity, water, and heat. The process is efficient and does not produce harmful emissions.
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.
Which cell can produce hydrogen gas fuel by using electricity to decompose water?
The cell that can produce hydrogen gas fuel by using electricity to decompose water is an electrolyzer. Electrolyzers use an electric current to split water (H2O) into hydrogen (H2) and oxygen (O2) gases through a process called electrolysis.
What are the two gases used to produce electricity in fuel cells?
The two gases used to produce electricity in fuel cells are hydrogen (H2) as the fuel and oxygen (O2) as the oxidant. In a fuel cell, hydrogen is fed to the anode (negative electrode) and oxygen is supplied to the cathode (positive electrode), where they react to produce water, heat, and electricity through an electrochemical process called the oxidation-reduction reaction.
How is a water fuel cell made that replaces the gas tank on a car?
The water fuel cell is a single unit that works with the fuel pump. The water will conduction electricity into the water to produce oxygen and hydrogen. It does not replace the fuel pump but it is added to the side.
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.
What element is used in a fuel cell?
Hydrogen is the most commonly used element in fuel cells. It acts as the fuel source that reacts with oxygen to produce electricity, with water and heat as byproducts.
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.
Coal is used as fuel to produce what?
in power stations to produce electricity,,,
What are two types of electromagnetic cells?
Two types of electromagnetic cells are photovoltaic cells, which convert sunlight into electricity, and fuel cells, which produce electricity through chemical reactions between fuel and oxygen.
Where was the fuel cell invented?
The fuel cell was invented in the United Kingdom by Sir William Grove in 1839. Grove's early fuel cell, known as the Grove cell, used hydrogen and oxygen to produce electricity, marking the first practical demonstration of this technology. His work laid the foundation for further developments in fuel cell technology, which has since evolved significantly.
Principle of operation of a fuel cell?
A fuel cell generates electricity through an electrochemical reaction between a fuel (like hydrogen) and an oxidant (like oxygen). The fuel is oxidized at the anode, releasing electrons that flow through an external circuit to the cathode, where they combine with the oxidant and protons to produce water and heat. This process generates electricity that can be used to power electrical devices.
