1 SEMINAR ON HY-WIRE TECHNOLOGY

2 INTRODUCTION Cars are immensely complicated machines, but they do an incredibly simple job. Cars are immensely complicated machines, but they do an incredibly simple job. Most of the complex stuff in a car is decided to turning wheel Most of the complex stuff in a car is decided to turning wheel The two basic elements that largely dictate car design today are 1. The internal combustion engine 2. Mechanical and hydraulic linkages The two basic elements that largely dictate car design today are 1. The internal combustion engine 2. Mechanical and hydraulic linkages

3 HY-WIRE BASICS The defining characteristic of the Hy-wire is that it doesnt have either of those two things: engine and mechanical and hydraulic linkages The defining characteristic of the Hy-wire is that it doesnt have either of those two things: engine and mechanical and hydraulic linkages Instead of an engine, it has a fuel cell stack Instead of an engine, it has a fuel cell stack Instead of mechanical and hydraulic linkages, it has a drive by wire system Instead of mechanical and hydraulic linkages, it has a drive by wire system

4 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. 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 provides a DC (direct current) voltage It can continually recharge a fuel cell by adding chemical fuel- hydrogen for an onboard storage tank It can continually recharge a fuel cell by adding chemical fuel- hydrogen for an onboard storage tank

5 Proton exchange membrane fuel-cell The type of fuel cell that is used in the The type of fuel cell that is used in the Hy-wire car is the Proton exchange membrane fuel cell. Hy-wire car is the Proton exchange membrane fuel cell. The four basic elements of a PEM fuel cell are:- The four basic elements of a PEM fuel cell are:- The anode, the negative post of the fuel cell The anode, the negative post of the fuel cell The cathode, the positive post of the fuel cell The cathode, the positive post of the fuel cell

6 Electrolyte Electrolyte It is the proton exchange membrane. It is the proton exchange membrane. It blocks electrons. It blocks electrons. The catalyst The catalyst It is a special material that facilitates the reaction of oxygen and hydrogen. 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 usually made of platinum powder very thinly coated onto carbon paper or cloth. It is rough and porous. It is rough and porous. The platinum-coated side of the catalyst faces the PEM. The platinum-coated side of the catalyst faces the PEM.

7 The working of PEMFC

8 Chemistry of a Fuel Cell Chemistry of a Fuel Cell Anode side: Anode side: 2H2 => 4H+ + 4e- 2H2 => 4H+ + 4e- Cathode side: Cathode side: O2 + 4H+ +4e- => 2H2O O2 + 4H+ +4e- => 2H2O Net reaction: Net reaction: 2H2 + O2 => 2H2O 2H2 + O2 => 2H2O
