PEMFC
Proton-Exchange Membrane Fuel Cell
A Promising Technology for Sustainable Energy
Proton-exchange membrane fuel cells are a type of fuel cell that has gained significant attention in recent years due to their potential for a wide range of applications. They typically convert hydrogen into electrical energy through an electrochemical process.
PEMFC Components
  • Anode
    The anode is where the fuel (hydrogen) is oxidized, releasing electrons and protons.
  • Proton Exchange Membrane (PEM)
    The PEM acts as a barrier that allows protons to pass through while blocking electrons.
  • Cathode
    The cathode is where oxygen reduction occurs, combining electrons from the anode with oxygen molecules to form water.
Advantages of PEMFCs
  • Low Operating Temperature
    The anode is where the fuel (hydrogen) is oxidized, releasing electrons and protons.
  • High Power Density
    PEMFCs can achieve high power densities, enabling them to power compact and lightweight devices.
  • Quick Start-up and Shutdown
    PEMFCs can start up and shut down quickly, making them well-suited for transportation applications.
  • Low Emissions
    PEMFCs produce only water and heat as byproducts, contributing to minimal environmental impact.
Applications of PEMFCs
  • Transportation
    PEMFCs are being developed for use in electric vehicles, buses, and even ships.
  • Stationary Power
    PEMFCs can be used as stationary power sources for backup power, remote communities, and off-grid applications.
