How does an fuel cell work?
A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode. In a hydrogen fuel cell, a catalyst at the anode separates hydrogen molecules into protons and electrons, which take different paths to the cathode. The electrons go through an external circuit, creating a flow of electricity.
How does a fuel cell work quizlet?
A fuel cell combines hydrogen and oxygen to produce electricity, heat, and water. Fuel cells are often compared to batteries. Both convert the energy produced by a chemical reaction into usable electric power.
What is a fuel cell describe the principle of working of a fuel cell with the reference to H2 O2?
A fuel cell is a device that generates electricity through an electrochemical reaction, not combustion. In a fuel cell, hydrogen and oxygen are combined to generate electricity, heat, and water.
How do fuel cells work GCSE?
Fuel is electrochemically oxidised. When fuel enters the cell, it reacts with oxygen. This occurs through an oxidation reaction, resulting in the creation of a potential difference inside the cell.
How does a fuel cell work article?
Fuel cells are electrochemical devices that convert the chemical energy of a chemical reaction directly into electrical energy and heat. In principle, a fuel cell operates like a battery, but does not run down or require recharging like a battery as long as fuel and oxidant are supplied.
How does fuel cell produce energy?
Hydrogen fuel cells produce electricity by combining hydrogen and oxygen atoms. The hydrogen reacts with oxygen across an electrochemical cell similar to that of a battery to produce electricity, water, and small amounts of heat. Many different types of fuel cells are available for a wide range of applications.

How does a fuel cell create an electric charge quizlet?
At the anode, the H2 loses electrons and becomes H+At the cathode, H+ ions combine with electrons and O2 to produce H2O. Electrons (e-) flow through the wire to produce electricity. Fuel (H2) is pumped into the cell. H+ flows through the electrolyte to the cathode.
What are fuel cells explain the construction and working of fuel cell?
A fuel cell is a lot like a battery. It has two electrodes where the reactions take place and an electrolyte which carries the charged particles from one electrode to the other. In order for a fuel cell to work, it needs hydrogen (H2) and oxygen (O2). The hydrogen enters the fuel cell at the anode.
