Introduction:
A hydrogen fuel cell vehicle is a vehicle that uses Hydrogen as source of
fuel.Hydrogen vehicles include hydrogen-fueled space rockets, as well as
automobiles and other transportation vehicles. The power plants of such vehicles
convert the chemical energy of hydrogen to mechanical energy either by burning
hydrogen in an internal combustion engine, or, more commonly, by reacting
hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of
hydrogen for fueling transportation is a key element of a proposed hydrogen
economy.
What is a HFC ?
A Hydrogen fuel cell is a device that converts chemical potential energy
(energy stored in molecular bonds) into electrical energy. A Proton Exchange
Membrane or a PEM cell uses hydrogen gas (H2) and oxygen gas (O2) as fuel.
The products of the reaction in the cell are water, electricity, and heat.
Components of HFC
There are four basic elements of a PEM Fuel Cell:
● The anode, the negative post of the fuel cell, has several jobs. It conducts the
electrons that are freed from the hydrogen molecules so that they can be
used in an external circuit. It has channels etched into it that disperse the
hydrogen gas equally over the surface of the catalyst.
Components of HFC
● The cathode, the positive post of the fuel cell, has channels etched into it that
distribute the oxygen to the surface of the catalyst. It also conducts the
electrons back from the external circuit to the catalyst, where they can
recombine with the hydrogen ions and oxygen to form water.
● The electrolyte is the proton exchange membrane. This specially treated
material, which looks something like ordinary kitchen plastic wrap, only
conducts positively charged ions. The membrane blocks electrons. For a
PEMFC, the membrane must be hydrated in order to function and remain
stable.
Components of HFC
● The catalyst is a special material that facilitates the reaction of oxygen and
hydrogen. It is usually made of platinum nanoparticles very thinly coated onto
carbon paper or cloth. The catalyst is rough and porous so that the maximum
surface area of the platinum can be exposed to the hydrogen or oxygen. The
platinum-coated side of the catalyst faces the PEM..
Components of HFC
● As the name implies, the heart of the cell is the proton exchange membrane.
It allows protons to pass through it virtually unimpeded, while electrons are
blocked. So, when the H2 hits the catalyst and splits into protons and
electrons (remember, a proton is the same as an H+ ion) the protons go
directly through to the cathode side, while the electrons are forced to travel
through an external circuit. Along the way they perform useful work, like
lighting a bulb or driving a motor, before combining with the protons and O2
on the other side to produce water.
How does a hydrogen fuel cell car work ?
Hydrogen fuel cell car or HFC work by converting the potential energy of the
hydrogen into chemical energy thent converting into mechanical energy to
generate the motive power.
HFC cars consist of a cell that produces the electrical power to drive the motor.
HFC uses compressed Hydrogen and air as the fuel source and in exhaust it out
put water.
How does a hydrogen fuel cell car work ?
Pressurized hydrogen gas (H2) entering the fuel cell on the anode side. This gas
is forced through the catalyst by the pressure. When an H2 molecule comes in
contact with the platinum on the catalyst, it splits into two H+ ions and two
electrons (e-). The electrons are conducted through the anode, where they make
their way through the external circuit (doing useful work such as turning a motor)
and return to the cathode side of the fuel cell.
How does a hydrogen fuel cell car work ?
Meanwhile, on the cathode side of the fuel cell, oxygen gas (O2) is being forced
through the catalyst, where it forms two oxygen atoms. Each of these atoms has a
strong negative charge. This negative charge attracts the two H+ ions through the
membrane, where they combine with an oxygen atom and two of the electrons
from the external circuit to form a water molecule (H2O).
How does a hydrogen fuel cell car work ?
All these reaction occurs in a so called cell stack. The expertise then also
involves the setup of a complete system around core component that is the cell
stack.
The stack will be embedded in a module including fuel, water and air
management, coolant control hardware and software. This module will then be
integrated in a complete system to be used in different applications.
Due to the high energetic content of hydrogen and high efficiency of fuel cells
(55%), this great technology can be used in many applications like transport (cars,
buses, forklifts, etc) and backup power to produce electricity during a failure of the
electricity grid.
Production Of Hydrogen:
There is mainly two type of production process of Hydrogen
1. Electrolysis
2. Steam reforming
Production Of Hydrogen:
1. Electrolysis:
In this process , direct current is passed through the water and
produces Hydrogen at cathode and Oxygen at anode. Salt is added to the water to
make the water more conductive.
Anode Reaction: 2H2O → O2 + 4H+ + 4e-
Cathode Reaction: 4H+ + 4e- → 2H2
Production Of Hydrogen:
2. Steam reforming:
This process is mainly used in the industry. Here hydrogen is taken out form the
natural gases like Methane.
For this process high temperature (700–1100 °C) steam (H2O) reacts with
methane (CH4) in an endothermic reaction to yield syngas.
CH4 + H2O → CO + 3 H2
In a second stage, additional hydrogen is generated through the lower-
temperature, exothermic, water gas shift reaction, performed at about 360 °C.
CO + H2O → CO2 + H2
Advantages of HFCV over ICV:
● By converting chemical potential energy directly into electrical energy, fuel
cells avoid the “thermal bottleneck” (a consequence of the 2nd law of
thermodynamics) and are thus inherently more efficient than combustion
engines, which must first convert chemical potential energy into heat, and
then mechanical work.
● Direct emissions from a fuel cell vehicle are just water and a little heat. This is
a huge improvement over the internal combustion engine’s litany of
greenhouse gases.
Advantages of HFCV over ICV:
● Fuel cells have no moving parts. They are thus much more reliable than
traditional engines.
● Hydrogen can be produced in an environmentally friendly manner, while oil
extraction and refining is very damaging.
Conclusion:
Hydrogen Fuel cell vehicles are currently being researched for their feasibility of
widespread usage in automobiles and other forms of transportation.
As the hydrogen is not naturally found on the earth so extracting it from water or
from any other substance is expensive and produces greenhouse gases as
byproduct .
But now some petrol pump in Ireland and USA are producing hydrogen
at their own mini plant by using solar and wind power as source of electricity.
We could hope see a clean source of a fuel for the vehicle in near future.
