Welcome to the situation in this lecture, we will discuss about fuel cell hybrids work, what are the
advantage, benefits and limitations of fuel cell.
So let's discuss how Will can be used in electric vehicle.
Fuel cell is a device that converts chemical energy of fuel and oxidizing agent into the electricity
like a battery.
Hydrogen is appropriate as a fuel for fuel cell as it produced the water H2O as a byproduct which is
safer for the environment, which compared to conventional CO2 emission.
Otherwise, hydrocarbons like methane, natural gas, ethanol, etc., can also be used as a fuel in
the fuel cell.
And oxygen is used as a oxidizing agent in the process.
And mattress batteries, fuel sell needs, continuous supply of hydrogen and oxygen to produce electricity.
That's how it's different than the conventional battery.
The fuel cell is not a new device.
In fact, the first fuel cells were developed in 1838 by Sir William Group, which is even before the
development of waterlilies, a battery that was developed in 1859.
But the first commercial use of hydrogen fuel cells comes almost a century later in 1932, which were
developed by Francis Thomas Makone, also known as the Back Unseld.
So without going deep into the chemistry of FuelCell, let's discuss more about its pros and cons for
electric vehicles.
System compared the fuel cell with conventional engine midwicket.
Not that same fuel can be used with both fuel cell and I see energy.
But efficiency of fuel cell is 40 to 60 percent, which is two to three times higher than that of CNG.
This is the main benefit of fuel cell, our CNG if we compare fuel cell with the battery.
We know that battery takes much time to charge, whereas fuel cell gives benefit of repealing super
fast as like any other CNG vehicles available in the market today.
So.
What is the problem with FuelCell after having such benefits, our both, I think, and Bedri, let's
discuss about limitations of FuelCell.
Main thing is the energy density of hydrogen, which is very low, that demands higher volume and higher
out fuel.
Thus, despite of higher specific energy, hydrogen needs larger and bulky fuel tank.
The other commercial aspect is Supply-Chain.
Because of lower market acceptance, availability of both the station and supplier of hydrogen is the
issue.
So if you are interested in knowing more about FuelCell Vehicle yet, it's a small task for you, search
for the latest and as well as past hydrogen based vehicle and started their performance and customer
review.
And don't forget to share the same in the comments section or the or discussion and knowledge.
So if we summarize.
Commercial use of hydrogen as a fuel, then we can see.
First, we started using hydrogen in icy engine with the vehicle, then we realized that we can have
higher efficiency with the fuel cell as well as we will get all the benefits of electric motor, our
icy engine.
What size and weight of fuel cell is the.
This trend is to use both military as well as fuel cell run, electric car or vehicle, this way we
can solve three problems.
The first, we can have a good vehicle range.
The second is we can have limited size of fuel tank as we have battery to and we can fill it quickly
and get rid of spending hours of charging the vehicle.
Here is the latest fuel cell vehicle from the unit that I captured during the Auto Expo 2020 held at
Noida, India.
But it's not still enough from the commercial point of view, adding fuel cell to battery increased
the initial cost and problem of supply change of hydrogen remains there.
Thus, if we can reduce the charging time of battery at some acceptable level, then that is nothing
more better than your battery electric vehicle.
However, use of other energy sources like ultra capacitor and flywheel, along with the battery, may
help extending battery performance and vehicle range.
So hope you got the idea about FuelCell and its association with the electric vehicle and see you in
the next lecture.
Thank you.
