Working of Fuel Cells

Working of Fuel Cells

The basic idea behind fuel cells is the direct conversion of chemical energy via an electrochemical process into electrical energy. Fuel cells create energy with a substantially lower environmental impact than traditional combustion-based power generation, which releases toxic emissions. A fuel cell is composed of three basic components: an anode, a cathode, and an electrolyte. The electrochemical reaction occurs when a fuel, usually hydrogen, is added to the anode and oxygen from the air is delivered to the cathode. The resultant products are heat, water, and electricity.

Types of Fuel Cells

There are numerous varieties of fuel cells, each with special qualities appropriate for different applications. The most typical kinds consist of:

  1. Proton Exchange Membrane Fuel Cells (PEMFC)
    • It is extensively employed in transportation-related applications, including fuel-cell automobiles, etc.
    • Work in a temperature range of 80 to 100 degrees Celsius.
    • Make use of a solid polymer electrolyte membrane, which is often composed of a substance that conducts protons.
  2. Solid Oxide Fuel Cells (SOFC)
    • Ideal for industrial applications and stationary power generation.
    • Function at temperatures between 800 and 1000 degrees Celsius.
    • Use an electrolyte made of solid ceramic.
  3. Molten Carbonate Fuel Cells (MCFC)
    • frequently used in industrial settings and large-scale power plants.
    • Function at high temperatures (between 600 and 700 degrees Celsius).
    • Use an electrolyte made of melted carbonate.
  4. Alkaline Fuel Cells (AFC)
    • Currently finding use in specialized fields after being employed in space missions in the past.
    • Utilize low temperatures (between 60 and 80 degrees Celsius).
    • Use alkaline electrolytes.
