Fuel cell

1. Hydrogen Fuel Cell Technology An Overview of Clean Energy Source

2. What is a Hydrogen Fuel Cell? A hydrogen fuel cell is a device that converts chemical energy from hydrogen into electricity through an electrochemical reaction. It produces only water and heat as byproducts, making it an eco-friendly energy source.

3. How Does a Hydrogen Fuel Cell Work? 1. Hydrogen gas (H2) is supplied to the anode. 2. Hydrogen molecules split into protons and electrons. 3. Electrons flow through an external circuit, generating electricity. 4. Protons pass through the electrolyte to the cathode. 5. Oxygen (O2) is supplied at the cathode, where it combines with protons and electrons to form water (H2O).

4. Types of Hydrogen Fuel Cells 1. Proton Exchange Membrane Fuel Cell (PEMFC) 2. Alkaline Fuel Cell (AFC) 3. Phosphoric Acid Fuel Cell (PAFC) 4. Molten Carbonate Fuel Cell (MCFC) 5. Solid Oxide Fuel Cell (SOFC)

5. Applications of Hydrogen Fuel Cells - Hydrogen-powered vehicles (cars, buses, trains) - Portable and backup power systems - Power generation for industrial and commercial use - Space exploration (NASA uses hydrogen fuel cells in spacecraft)

6. Advantages and Challenges Advantages: - Zero emissions (only water and heat produced) - High efficiency and reliability - Renewable and sustainable energy source Challenges: - High production and infrastructure costs - Hydrogen storage and transportation issues - Limited refueling stations

7. Future of Hydrogen Fuel Cells - Development of green hydrogen from renewable sources - Advancements in fuel cell efficiency and durability - Expansion of hydrogen refueling infrastructure - Increasing adoption in automotive, aerospace, and power sectors
