    presentation on NANO-TECH REGENERATIVE FUEL CELL presentation on NANO-TECH REGENERATIVE FUEL CELL Presentation Transcript

    • NANO-TECH REGENERATIVE FUEL CELL SUBMITTED BY SUBHRASREE DE 4 th yr electrical NETAJI SUBHAS ENGG COLLEGE Department of electrical ENGINEERING
    • ABSTRACT
        • Integration of NANO TECHNOLOGY and REGENERATIVE FUEL CELL provides a better way for using hydrogen as a fuel.
        • By using this fuel cell with nano tech we can easily onboard the hydrogen storage equipment on automobiles and it will give more power without any harmful emissions.
        • Water is obtained as a byproduct from fuel cell.
        • Hydrogen is regenerated from the byproduct (water).
        • Maximum efficiency will be obtained than internal combustion engines.
    • I NTRODUCTION
      • NANO-TECH REGENERATIVE FUEL CELL refers to the effective production of power in automobiles without undergoing into combustion. It will overcome all the problems which are being faced today.
      • The integration of nanotechnology and fuel cell will lead to a new era in alternative fuels. Nanotechnology is providing a key to improving the fuel cell performance.
      • We provide "Cooler, Cleaner, Greener" power and energy solutions that also include "Pollution Free Power" and "Carbon Free Energy" systems, and all provide "Renewable Energy Credits."
      • The regenerative PEM fuel cell system that is combined with solar cells can continuously produce electricity .
    • LAYOUT OF REGENERATIVE FUEL CELL
    • FUEL CELL
      • A fuel cell is an electrochemical conversion device. It produces electricity from fuel (on the anode side) and an oxidant (on the cathode side), which react in the presence of an electrolyte.
      • In a fuel cell the fuel is also oxidized but the resulting energy takes the form electricity.
      • Anode side:
      • 2H2  4H+ + 4e-
      • Cathode side:
      • O2 + 4H+ + 4e-  2H2O
      • Net reaction:
      • 2H2 + O2  2H2O
    • FUEL CELL
    • CARBON NANOTUBES
      • Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure.
      • since the diameter of a nanotube is on the order of a few nanometers (approximately 1/50,000th of the width of a human hair)
      • The chemical bonding of nanotubes is composed entirely of sp2 bonds, similar to those of graphite.
      • It also makes the onboard hydrogen storage easier.
    • CARBON NANOTUBES
    • NANO COMPOSITE MATERIAL
    • REGENERATION OF HYDROGEN
      • The BY-PRODUCT from the fuel cell(water) is used to regenerate the fuel
      • A reversible fuel cell can accomplish “Electrolysis" through the supply of electricity to the cell
      • This allows one to consider the completely renewable production of electricity by using a renewable energy supply (e.g., solar, wind) to produce hydrogen and oxygen from water.
      • REGENERATION
      • 2H2O(l) -> 2H2(g) + O2(g)
    • REGENERATION BY ELECTROLYSIS
    • WORKING
      • Hydrogen from carbon nanotube is entered into the fuel cell.
      • Hydrogen reacts with oxygen in polymer electrolyte membrane and the chemical energy is produced.
      • In fuel cell, chemical energy is converted into electrical energy .
      • O2 + 4H+ + 4e-  2H2O 2H2  4H+ + 4e-
      • Electrolysis of water is the decomposition of water (H2O) into oxygen (O2) and hydrogen gas (H2) due to an electric current being passed through the water .
      • Water is obtained from the reaction.
      • The byproduct water is used to regenerate the hydrogen by the process of electrolysis.
      • 2H2O(l) -> 2H2(g) + O2(g)
    • Overview of PROTOTYPE nanotech regenerative fuel cell VEHICLE
    • FUEL CELL VEHICLE
    • BENEFITS
      • High Power Densities
      • Onboard storage of Hydrogen

    • conclusion
      • The NANOTECH REGENERATIVE FUEL CELLS provides solutions for the problems, which are effectively in internal combustion engines .
      • Here, developments in fuel cells are making it useful in ultimate ways.
      • It concludes that our environment and renewable resources will be preserve.
      • It will lead to a new evolution in automobiles.
