What is meant by fuel cell definition?
An electrochemical device that converts chemical energy directly into electricity.
What is fuel cell with example?
Comparison of fuel cell types
| Fuel cell name | Electrolyte | Efficiency |
|---|---|---|
| Cell | ||
| Proton-exchange membrane fuel cell | Polymer membrane (ionomer) | 50–70% |
| Redox fuel cell (RFC) | Liquid electrolytes with redox shuttle and polymer membrane (ionomer) | |
| Phosphoric acid fuel cell | Molten phosphoric acid (H3PO4) | 55% |
What is ment by fuel cell?
A fuel cell is a device that converts chemical energy into electricity. It consists of an electrolyte and two electrodes. It generates electricity by means of chemical reactions occurring at the electrodes. A chemical catalyst may be used to speed up the chemical reaction in the cell.
What is in a fuel cell?
A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode.
What is fuel cell in chemistry class 12?
Hint:A fuel cell is an electrochemical cell that converts the chemical energy into electrical energy. Hydrogen is used as a fuel and oxygen is used as an oxidizing agent which converts electrochemical energy into electricity through a pair of redox reactions.
What is fuel cell and types?
Fuel cells are classified primarily by the kind of electrolyte they employ. This classification determines the kind of electro-chemical reactions that take place in the cell, the kind of catalysts required, the temperature range in which the cell operates, the fuel required, and other factors.
What is fuel cell used for?
Fuel cells can be used in a wide range of applications, including transportation, material handling and stationary, portable, and emergency backup power. Hydrogen can be used in fuel cells to generate power using a chemical reaction rather than combustion, producing only water and heat as byproducts.

What is fuel cell Class 11?
A fuel cell can be defined as an electrochemical cell that generates electrical energy from fuel via an electrochemical reaction. These cells require a continuous input of fuel and an oxidizing agent (generally oxygen) in order to sustain the reactions that generate the electricity.
What is fuel cell Ncert?
A fuel cell can be described as an electrochemical cell which, through an electrochemical reaction, generates electrical energy from the fuel. To maintain the reactions that produce electricity, these cells require a continuous input of fuel and an oxidizing agent (generally oxygen).
What is the definition of a fuel cell?
fuel cell. n. (Chemistry) a cell in which the energy produced by oxidation of a fuel is converted directly into electrical energy.
How does a fuel cell convert chemical energy into electricity?
A fuel cell is an electrochemical cell that converts the chemical energy from a fuel into electricity through an electrochemical reaction of hydrogen fuel with oxygen or another oxidizing agent.
How does the US Department of Energy work on fuel cells?
View the Hydrogen and Fuel Cell Technologies Office’s fuel cell animation to see how a fuel cell operates. The U.S. Department of Energy (DOE) is working closely with its national laboratories, universities, and industry partners to overcome critical technical barriers to fuel cell development.
How are electrons freed in a fuel cell?
In this reaction, electrons are freed from the hydrogen in the fuel cell by a catalyst, and gain energy from the chemical reaction binding hydrogen and oxygen; this provides a source for electric current. The exhaust of hydrogen fuel cells consists simply of water.
