This document discusses hydrogen as a potential future fuel. It outlines the properties of hydrogen, including that it is the most abundant element in the universe. It then discusses how hydrogen could power a future "hydrogen economy" as an alternative to fossil fuels. The document details various production methods for hydrogen as well as fuel cells, which generate electricity through a chemical reaction between hydrogen and oxygen. It concludes that hydrogen is a renewable and clean energy source that could power automobiles, processors and power plants in an environmentally-friendly way.

4. Hydrogen has the following physical parameters:
• Hydrogen is the smallest of all atoms.
• Melting temperature — (-259.2) degrees Celsius.
• Boiling temperature — (-252.76) degrees Celsius.
• Hydrogen is insoluble in water
• Hydrogen is 14.5 times lighter than air.

5. Currently, most the energy in the USA comes from fossil
fuels.
However, there are problems with fossil fuels….

6. Main problems with fossil fuels
• They will eventually be depleted.
• They cause a variety of environmental problems.
• They force the U.S. to be dependent on middle
eastern countries.
• Non-renewable
• Effect on Human Health
• Need Huge Amount of Reserves

7. •Hydrogen is not a Source of Energy
It is an Energy Carrier: That means of transferring energy
from an energy source to an energy user
• It is a form of Energy storage.
•You need to generate energy from source like
sun,coal,natural gas or uranium.
•To extract the hydrogen(H2) from a source material like
water and natural gas.

9. What is Hydrogen Fuel Cell ?
• A hydrogen fuel cell is a electrochemical conversion
device,which means that it uses chemical to generate
electricity.
• The most common chemicals in fuel cells are hydrogen and
oxygen.
• Fuel cells are a very clean form of energy because in a
hydrogenfuel the only byproducts are water and electricity
• Fuel cells have a wide variety uses
• Hydrogen is the most plentiful element in the universe

10. Types of Fuel Cell
1. Proton Exchange Membrane (PEM)
2. Phosphoric Acid
3. Molten Carbonate Fuel Cell
4. Alkaline Fuel Cell
5. Regenerative Fuel Cell

11. • A hydrogen fuel cell works by fusing together hydrogen and
oxygen form water.
• Hydrogen is stored compressed in a liquid form.
• The fusion of atoms produces an electrical charge.
• The charge is collected by two conductor plates.

14. • It is a renewable energy source and bountiful in
supply
• It is practically a clean energy source
• Hydrogen energy is non-toxic
• It is far more efficient than other sources of energy
• Used for powering space ships

15. • Hydrogen energy is expensive.
• Storage complication.
• It is not safest source of energy.
• Hydrogen energy cannot sustain the polution.

16. • The Future Fuel Sources are Environment-friendly.
• Through the year these sources are available
without affecting the environment.
• Using this fuel helps diminish warming.
• Helps conserve resources.
