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

3. INTRODUCTION
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.
5. 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
7. 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.
10. 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)→
12. 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)→
15. BENEfITS
