Context: Prime Minister of India will inaugurate the first indigenously developed and built hydrogen fuel cell ferry. The vessel constructed by Cochin Shipyard Ltd will be inaugurated in virtual mode from Thoothukudi.
Hydrogen Fuel Cell
oElectrolyte: The fuel cell contains an electrolyte, a substance that conducts ions. Commonly used electrolytes include proton exchange membrane (PEM), phosphoric acid, molten carbonate, and solid oxide.
oAnode: Hydrogen gas is fed into the anode side of the fuel cell. At the anode, hydrogen molecules (H2) are split into protons (H+) and electrons (e-) through a process called electrolysis.
oCathode: Oxygen from the air is supplied to the cathode side of the fuel cell. The oxygen molecules combine with electrons and protons that have traveled through an external circuit from the anode, creating water (H2O) as a byproduct.
oElectrochemical Reaction: The chemical reactions occurring at the anode and cathode generate an electric current. This electricity can be utilized to power electric vehicles, and electronic devices, or provide electricity for various applications.
