Air Breathing Magnesium- Sodium Chloride Based Fuel Cell

  • About:  A semiconducting layer of Cupric Oxide grown over Copper substrate was used in a Magnesium- Sodium Chloride based fuel cell. 
  • Cost Effective: In this fuel cell,  semiconductor material has been used for air cathode systems making the cell cost effective as compared to use of expensive chemical element Platinum around the world.
  • Environment Friendly: The fuel cell is promoted as environmentally friendly since it operates by utilizing air for breathing and saline water as fuel. 
  • During its operation, the cell generates only electricity and heat, emitting only water as a byproduct.

What is a Fuel Cell?

  • About: 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. 
  • Advantages: Fuel cell systems are a clean, efficient, reliable, and quiet source of power. Fuel cells do not need to be periodically recharged like batteries, but instead continue to produce electricity as long as a fuel source is provided. 
  • Applications: Providing power to homes and businesses, keeping critical facilities like hospitals, grocery stores, and data centers up and running, and moving a variety of vehicles including cars, buses, trucks, forklifts, trains, and more.
