2. HYDROGEN
It is the most
abundant element,
accounting for 75%
of the mass of the
universe.
FACTS:
-Fuel Cell Car refuels in 3-7
minutes
-Hydrogen pressure
700 Bar
-Fuel Consumption:
100 km/kg Hydrogen
-Fuel Economy:
1.9 Times CNG
Hydrogen is an energy carrier
POWERSTHE SUN;
IT WILL POWEROUR WORLD
Energy Density of Hydrogen:
120 MJ/kg
«2.5 times more than
gasoline»
Hydrogen can be
produced from
different sources,
including
renewable
sources.
It can be given as
compressed gas or
liquid. It can be used
by pipeline in some
regions.
It can be produced on-
site from electricity and
water using an
electrolyser or it can be
produced from natural
gas with reformer.

3. What is a Fuel Cell?
Emissions only Clean Water!

4. Fuel Cell Stack

Sealing Elements
For Single Cell:
OCV= 1-1.2 Volts
Voltage Under Load=0.45-0.65 Volts

6. Comparison of Fuel Cell with Batteries

7. Fuel Cell Values for Cars
 It can operate quieter and more efficiently with the same comfort and
the same comfort as conventional cars and in the same environments.
 Fuel cell cars have the advantages of having built-in power generation in
electric car compositions on the vehicle.
 Heavy battery in electric cars, long charging-discharge time
 70% reserve of lithium element in South America, rest China, Canada,
Brazil
 Operating costs are the same as diesel and natural gas vehicles in today's
conditions.

8. EMISSIONS
Fuel cell electric cars have
zero exhaust emissions.
 Fuel cell electric vehicles play an
important role in the emission
reduction targets required for ultra-
low emission zones.
 They do not produce nitrogen oxide,
sulphur dioxide or particulate matter.
Hydrogen production from renewable
energy sources provides full carbon
neutrality from well to wheel
perspective and significantly reduces
carbon dioxide emissions in cities.


9. Fuel cell integration on the car platform Fuel cell electric
vehicles, parts of
battery electric
vehicles
Shares 90%.
Fuel cell cars are actually
battery-fuel cell hybrid
electric cars that provide the
best performance of both
technologies.
The only difference is
a fuel cell power
module and hydrogen
storage tanks.

11. What are the problems that have been
overcome in the last 20 years?
 Hydrogen Storage Problems Exceeded (700 bar composite tank- 1.5 kg H2/kg)
 Increasing number of manufacturers and R&D studies
 Fuel Cell Life Problems (10,000 hours and above)
 Fuel Cell unit volume and weight (3 kW/L and 2kW/kg)
 Cold Working Tests
 Mass Production Costs
 Real-terms usage data of vehicles with rental

18. New Mirai – 2022 Model – Range=650 km

19. Maintenance
 Maintenance is very easy, just like electric vehicles, as
there are not many moving parts.
 Technical personnel who can maintain electric vehicles
will also be able to maintain buses powered by a fuel cell
system after a small training.
 A team will also need to be trained for emergency
maintenance of the fuel cell.


20.  The world has had a technology that has
been widespread and commercialized in
fuel cells for 20 years

 A technology that has been performed
performance tests in the rental system
for 10 years before the sales of mass-
produced cars
 In many countries around the world, the
use of hydrogen-powered fuel cell
electric buses for emission reduction has
increased
The use of hydrogen-
powered fuel cell
electric buses to
reduce emissions has
increased around the
world

21. Lithium
 More than 60 percent of the world's lithium reserves are in Latin America (Chile
and Argentina), while other sources are in China (22 percent) and Australia (17
percent).
