3. WHAT IS A FUEL CELL ?
• A Fuel cell is an electro chemical
cell that converts chemical energy of
a fuel into electrical energy.
• Electricity is generated due to fuel
and oxidising agent.
• The reactants flow into the cell and
the reaction products flow out of it,
while the electrolyte remains within
it.
• Fuel cells can operate continuously .
• Fuel cells are different from
conventional electrochemical cells

4. HYDROGEN FUEL CELL
VEHICLE
• A hydrogen fuel cell uses
hydrogen as its fuel and
oxygen as its oxidant.
• A hydrogen vehicle is an
alternative fuel vehicle that
uses hydrogen as its onboard
fuel for motive power.
• The power plants of such
vehicles convert the chemical

5. SOURCES

6. STORAGE
• Hydrogen has a very less volumetric energy
density at ambient conditions .
• A Recent study by Dutch researcher Robin
Gremaud has shown that metal hydride
hydrogen tanks are actually 40-60 lighter than
an equivalent energy battery pack on an electric
vehicle permitting greater range for H2 cars.
• Two storage options .
1. Direct hydrogen .
2. Onboard fuel processor.

7. INFRASTRUCTURE
• The hydrogen infrastructure
consists mainly of industrial
hydrogen pipeline transport
and hydrogen-equipped filling
stations like those found on a
hydrogen highway.
• The California hydrogen
highway is an initiative to build
a series of hydrogen refueling
stations along that state.

8. Design & Engineering
• Fuel cells come in many varieties; however,
they all work in the same general manner.
They are made up of three segments which
are sandwiched together: the anode, the
electrolyte, and the cathode.
• Two chemical reactions occur at the interfaces
of the three different segments.

10. WHY HYDROGEN FUEL CELLS ?
• Aspects of engines as well
as batteries.
• Estimates that FC
Vehicles can achieve
equivalent of 80
miles/gallon gasoline.
• PEMFCs idea for light-
duty vehicles, buildings
and much small
apllications.
• High efficiency, zero
emission.

11. VEHICLES
 Many companies are currently researching the
feasibility of building hydrogen cars, and some
automobile manufacturers have begun developing
hydrogen cars
 Pearl Hydrogen Power Sources of
Shanghai, China, unveiled a hydrogen
bicycle at the 9th China International
Exhibition on Gas Technology,
Equipment and Applications in 2007.
 Companies such as Boeing,
Lange Aviation, and the
German Aerospace Center
pursue hydrogen as fuel for
manned and unmanned airplanes
OTHER APLLICATIONS is in Buses, Submarines , Space travel , and combined

12. CRITICISM
• Storage is complicated
• Limited range
• Expensive fuel
• Still a fossil fuel?
 Energy carrier, not energy source
• *Infrastructure*
• Politics
• Fuel cell overheating

13. NUTSHELL
• Hydrogen is the only type of energy that can
provide wholesale substitute for foreign oil
within a decade.
• Clean, twice as efficient as internal
combustion , and plentiful.
• Though hydrogen is an energy carrier and
not energy source , there are wide range of
sources like wind, solar energy, nuclear
energy, electrolysis of water and methane
from which hydrogen is produced.
