Description
The Centre for Fuel Cell Technology (CFCT) at the International Advanced Research Centre for Powder Metallurgy and New Materials recently unveiled a mobile Proton Exchange Membrane Fuel Cell (PEMFC)-based backup power solution for telecom towers, designed with a plug-and-play model.
About Proton Exchange Membrane Fuel Cell (PEMFC)
A Proton Exchange Membrane Fuel Cell (PEMFC) is an electrochemical device that generates electricity by converting the chemical energy from hydrogen and oxygen through a series of redox reactions. Unlike conventional batteries that store energy, PEMFCs require a continuous supply of hydrogen fuel and oxygen, typically sourced from the air, to maintain the chemical process and produce electricity.
Working Principle
The process begins with hydrogen gas being introduced to the anode, where it is oxidized, releasing protons. These protons travel through a polymer membrane to the cathode, where they combine with oxygen to generate electricity and water. This reaction makes PEMFCs a highly efficient and environmentally friendly energy source.
Advantages And Features
They offer a compact and powerful solution with high power density.
They operate on hydrogen fuel, which can be stored and transported for refueling, and require much less maintenance than traditional backup power systems.
PEMFCs provide a clean energy alternative with minimal environmental impact, making them ideal for reducing emissions and supporting green energy initiatives.
Applications
PEM fuel cells are increasingly used for backup power, particularly in telecom towers, where they offer quick start-up times and low operating temperatures. This makes them an efficient alternative to diesel generators.
The plug-and-play model for telecom towers is a step toward supporting national renewable energy goals while ensuring continuous communication for millions of users.
Other uses include portable power sources for devices like laptops, mobile phones, battery chargers, and even unmanned aerial vehicles (UAVs).
This innovative backup power solution demonstrates the growing role of hydrogen fuel cells in advancing clean, sustainable energy solutions.
