An Introduction to Fuel Cells – A fuel cell is an electrochemical device that continuously generates electricity without the need for any intermediate energy conversion. Hydrogen fuel cells work like batteries, but they do not need any recharging as they produce electricity if there is a supply of H2 and O2 as fuels.
A fuel cell is made up of a negative electrode (anode), and a positive electrode (cathode) sandwiched around an electrolyte. Hydrogen is fed to the anode, and the air is fed to the cathode. In a hydrogen fuel cell, a catalyst at the anode separates hydrogen molecules into protons and electrons, the electrons go through an external circuit, creating a flow of electricity. The protons migrate through the electrolyte to the cathode, where they unite with oxygen…
