Fuel cell

• Fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen) and an oxidizing agent (often oxygen) into electricity.
• First fuel cells were invented by Sir William Grove in 1838.
• The first commercial use of fuel cells came more than a century later following the invention of the hydrogen–oxygen fuel cell by Francis Thomas Bacon in 1932.
• Fuel cell uses the chemical energy of hydrogen or other fuels to cleanly and efficiently produce electricity
