Fuel Cells

Introduction

Fuel cells embody an intriguing frontier in energy innovation, especially at a moment when India is working towards sustainable progress and diminishing its carbon emissions. This piece examines the functionalities, uses, benefits, obstacles, and future possibilities of fuel cells specifically in the Indian context.

Understanding Fuel Cells

  • What are Fuel Cells?

    • Fuel cells are electrochemical systems that transform the chemical energy of a fuel (typically hydrogen) straight into electricity, producing water and heat as byproducts.

  • How Do They Operate?

    • The essential components include an anode (negative terminal), a cathode (positive terminal), and an electrolyte that allows protons to traverse through. Upon reaching the anode, hydrogen molecules dissociate into protons and electrons:
    • Anode Reaction: 2H₂ → 4H⁺ + 4e⁻
    • Cathode Reaction: O₂ + 4H⁺ + 4e⁻ → 2H₂O
    • This electrochemical process results in the production of electricity.

Types of Fuel Cells

  • Proton Exchange Membrane Fuel Cells (PEMFCs): Lightweight and ideal for transport and portable uses.
  • Solid Oxide Fuel Cells (SOFCs): Function at elevated temperatures and are suitable for stationary electricity generation.
  • Molten Carbonate Fuel Cells (MCFCs): Perfect for larger setups and industrial applications due to their high efficiency.
  • Alkaline Fuel Cells (AFCs): Traditionally utilized in aerospace endeavors.

Current State of Fuel Cell Technology in India

Growth Trajectory

  • India is progressively channeling investments into fuel cell technology as part of its shift towards a hydrogen economy.
  • Under the National Hydrogen Mission, initiated in 2021, the goals feature positioning India as a center for green hydrogen.
