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
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.
