WHAT IS HY-WIRE CAR
The HY-Wire Car runs on hydrogen fuel cells and it uses a drive-by-wire system. It means that the car is controlled electronically. The Hy-wire which is also known as Hydrogen drive-by-wire. It is a concept car from the General Motors. Which is introduced in the Year 2002.
In 2003, General Motors has also stated that it is confident that it can produce a commercially viable model of the Hy-Wire Car by the Year 2010. The design of the Hy-Wire Car is totally different than the other normal Cars

HY-WIRE BASICS
There are two basic elements that largely dictate car design they are: IC Engine and Mechanical and Hydraulic linkages
Instead of an engine, it has a fuel cell stack.
Instead of mechanical and hydraulic linkages, it has a drive by wire system, a computer actually operates the components that move the wheels
FUEL CELL–ON HY-WIRE
A fuel cell is an electrochemical energy conversion device that converts hydrogen and oxygen into water, producing electricity and heat in the process.
It provides a DC (direct current) voltage
It can continually recharge a fuel cell by adding chemical fuel- hydrogen for an onboard storage tank
Proton exchange membrane fuel-cell
The type of fuel cell that is used in the Hy-wire car is the Proton exchange membrane fuel cell.
There are four basic elements of a Proton Exchange Membrane fuel cell are:-
The anode, the negative post of the fuel cell
The cathode, the positive post of the fuel cell
Electrolyte
It is the proton exchange membrane .
It blocks electrons .
The catalyst
It is a special material that facilitates the reaction of oxygen and hydrogen.
It is usually made of platinum powder very thinly coated onto carbon paper or cloth.
It is rough and porous .
The platinum-coated side of the catalyst faces the PEM.
X-DRIVE
X-drive is the driver’s control unit .
It has two ergonomic groups , positioned to the left and right of a small LCD monitor.
The color monitor in the center of the controller displays speed, mileage, fuel level and the rear-view images from video cameras on the sides and back of the car, in place of conventional mirrors.
A second monitor, on a console beside the driver, shows you stereo, climate control and navigation information
