HY-WIRE CAR
Abstract
 In this we describe about car that runs on Hydrogen.
 We give in Hydrogen as source of fuel for running the vehicle.
 The technology used in this is “WIRE” systems.
 All the mechanical links we find in our daily car are eliminated.
 So its named as “HY-WIRE” car.
 In this car we doesn’t see gases as exhaust but water, it’s the only exhaust
we get.
Introduction
 This concept of car was developed in General Motors an US
automobile company.
 Its shape is just like an skateboard as it doesn’t have any body it
consists only of chassis.
 All the systems of the car are kept under the chassis which is only
11inch in thick.
 A computer is kept under the chassis which controls the system of
the car.
 Due to the concept of WIRE systems we doesn’t find any
mechanical and hydraulic linkages.
Chassis of Skateboard
Parts in Chassis
• Fuel cell stack
• By-wire system
• Hydrogen storage tank
• Wheel hub motor
• Lithium-ion battery
• Front electric motor
Design
• Due to hydrogen fuel cell drive system used by the Hy-wire, the conventional
car layout has been revamped.
• Without the need for a conventional engine block and transmission system
coupled to the steering column and pedals through mechanical linkage the
car's power system and single electric motor are built into a flat skateboard
configuration.
• Because all propulsion and energy storage systems are housed in the
skateboard, designers are free to arrange the passenger compartment
however they see fit.
• The skateboard itself contains crumple zones similar to those in conventional
automobiles.
Control unit of Vehicle
• In the control unit of the vehicle we have an computer
arranged under the chassis of the vehicle.
• This computer controls the speed of the vehicle.
• There is connection between the parts and computer using
wire system.
• There are LCD screens in front of the driver as they show the
road in front and behind the vehicle.

Power generation
• The basic idea is to use a catalyst to split a hydrogen molecule
(H2) into two H protons and two electrons (e-).
• Oxygen on the cathode side of the fuel cell draws H+ ions from
the anode side through a proton exchange membrane, but blocks
the flow of electrons.
• The electrons are attracted to the protons on the other side of
the membrane, but they have to move through the electrical
circuit to get there.
• The moving electrons make up the electrical current that powers
the various loads in the circuit, such as motors and the computer
system.
• On the cathode side of the cell, the hydrogen, oxygen and free
electrons combine to form water (H2O), the system's only
emission product.
Working
• On generation of electricity the motor which are fixed at the front
and back starts.
• The wheel hub motor which is fixed to the wheels of the vehicle
starts.
• The steering of the vehicle is connected to the computer of the
vehicle by wire which transmits signals regarding speed and braking
of vehicle.
• There are two grips provided on the steering which accelerates and
decelerates the vehicle.
Advantages of the hydrogen economy
 The elimination of pollution caused by fossil fuels - When
hydrogen is used in a fuel cell to create power, it is a completely
clean technology. The only by product is water. There are also no
environmental dangers like oil spills to worry about with hydrogen.
 The elimination of greenhouse gases - If the hydrogen comes from
the electrolysis of water, then hydrogen adds no greenhouse gases
to the environment. There is a perfect cycle -- electrolysis produces
hydrogen from water, and the hydrogen recombines with oxygen to
create water and power in a fuel cell.
 The elimination of economic dependence - The elimination of oil
means no dependence on the Middle East and its oil reserves.
 Distributed production - Hydrogen can be produced anywhere that
you have electricity and water. People can even produce it in their
homes with relatively simple technology.
Technological Hurdles
• The big question with the hydrogen economy is, "Where does
the hydrogen come from?" After that comes the question of
transporting, distributing and storing hydrogen. Hydrogen
tends to be bulky and tricky in its natural gaseous form.
