Proton Exchange Membrane Fuel Cell

Published on 11 Oct 2025

• The Centre for Fuel Cell Technology (CFCT) at ARCI, an autonomous institute under the Department of Science and Technology, has developed a fuel cell-based uninterrupted power supply for telecom towers. 

• Utilizing PEM (Proton Exchange Membrane) Fuel Cells, this clean energy solution offers reliable backup power during grid outages, featuring quick start-up and low-temperature operation as a viable alternative to diesel generators. 

• PEMFCs generate electricity with only water vapor as a byproduct, providing an environmentally friendly, high power density, and compact solution that runs on storable hydrogen fuel and requires less maintenance than traditional backups. 

• Their operation involves an electrochemical reaction where hydrogen is oxidized at the anode, protons travel through a membrane, and react with oxygen at the cathode to produce electricity and water..
