Proton Exchange Membrane Fuel Cell

Why in the news?                                                                                                                                                                                                                                     

            Recently, the Centre for Fuel Cell Technology (CFCT) at the International Advanced Research Centre for Powder Metallurgy and New Materials showcased a mobile Proton Exchange Membrane fuel cell (PEMFC)-based backup power solution for telecom towers using a plug-and-play model.

About Proton Exchange Membrane Fuel Cell:

• It is an electrochemical device that converts the chemical energy of hydrogen and oxygen into electricity through a series of redox reactions.
• Unlike traditional batteries, which store chemical energy internally, PEM fuel cells require a continuous supply of hydrogen fuel and oxygen (typically from the air) to sustain the chemical reaction and generate electricity.
• Working Principle: The working principle involves an electrochemical reaction where hydrogen gas is fed into the anode, oxidized to release protons, which then travel through a polymer membrane to the cathode, where they react with oxygen to produce electricity and water.
• They offer an environmentally friendly solution with high power density in a compact size.
• They run on hydrogen fuel, which can be stored and transported for refuelling, and require significantly less maintenance than traditional backup power sources.

Applications of the Proton Exchange Membrane Fuel Cell:

• These fuel cells provide reliable electricity with quick start-up times and operate at relatively low temperatures, making them a viable alternative to diesel generators.
• An innovative hydrogen fuel cell-based backup power solution for telecom towers, developed using a plug-and-play model can support national renewable energy goals while ensuring seamless connectivity for millions and promoting clean energy in the telecom sector.
• Portable power: specific applications include laptops, mobile phones, battery chargers and unmanned aerial vehicles.
