4. Why hydrogen as a Energy source
 Hydrogen is not a true fuel , but a carrier of energy.
 Hydrogen is abundantly found on Earth ,mostly as water .
 Processes such as electrolysis and steam reformation is used to separate the hydrogen
molecules.
 From the source of production of hydrogen , hydrogen can be classified mainly into
three types.
Green Hydrogen( from renewable sources)
blue hydrogen ( from hydrocarbons)
Brown hydrogen ( from coal)

5. Components Of Fuel cell electric
Vehicles

6.  Fuel tank – Since hydrogen is highly flammable and explosive the fuel
tanks are build strong and to high tolerances to prevent leakage. Hydrogen
Hydrogen from the fuel tank is fed to the fuel cell where the
electrochemical reaction takes place.
 Fuel cell- Chemical energy is converted into electrical energy inside the
fuel cell . In the fuel cell hydrogen from the fuel tanks and oxygen from the
air is converted into electricity and water. During this process heat is
produced as a by product.
 Motor- Using power from the fuel cell and the traction battery pack,
this motor drives the vehicle's wheels. Using power from the fuel
cell and the traction battery pack, this motor drives the vehicle's
wheels.

7. Working of Fuel cell

8. Inside the Anode
 Hydrogen from the fuel tank is fed into the fuel cell.
 Inside the anode , the platinum catalyst helps the hydrogen split into
hydrogen protons and electrons.
 The hydrogen proton from the anode flows into the cathode through the
polymer membrane and the electrons flows through an external circuit to
the cathode.
 H20 hydrogen protons+ electrons

9. Inside the cathode
 The electrons flows from the anode to the cathode via an external circuit and
combines with protons (hydrogen) and oxygen in the air to form water and heat.
 Electrons+ H + O2 H20 + heat

10. Advantages of FCEV
 NO Green house gas emissions- Fuel cell vehicles (FCVs) powered by pure
hydrogen emit no tailpipe GHGs, only heat and water.
 Silent, vibration free, EV like driving experience
 Higher driving range compared to EV’s- Since compressed hydrogen gas is
more energy dense than Lithium batteries, we can store a lot of hydrogen
in a small space. So, the hydrogen cars also manage to offer driving range
similar to that of petrol cars.
 Quick and easy to refill like a petrol/ diesel car

11. Disadvantages of FCEV
 Could cause more pollution if the hydrogen is produced using fossil fuels.
For instance the electricity to produce hydrogen can come from thermal
power plants running on fossil fuels.
 It is a new technology and thus might not be much reliable.
 FCVs are currently more expensive than conventional vehicles .Car makers must
continue to lower costs, especially for the fuel cell stack and hydrogen
storage, for FCVs to compete with conventional vehicles.
 Fuel cell durability is not as durable as internal combustion engines
especially in some temperatures and humidity ranges.

12. What does the Minister of Roadways
have to say about it?
 The Minister of Roadways,
Transportation and Highways
(MoRTH) has been regularly using the
Toyota Mirai, which is currently the
only such car on Indian roads.
 He also mentioned that the
government has started working on
Project Green Hydrogen and within a
year India will get cars, trucks and
buses that can run on green
hydrogen.
 The second-generation Mirai will be
manufactured at Toyota’s plant in
Karnataka in the future. The brand is
yet to give a timeline for the same.
However, it is likely to happen
sometime in 2024.
