In the twentieth century the automobile – perhaps more than any other invention – profoundly changed the way we live. The Ford Model T, then the dominant design, accounted for ¾ of all cars in America in 1912. Wheels, an engine and bodywork were sufficient to broaden our horizons, expand our opportunities and dramatically redefined our definition of community. The freedom and mobility that came with the new technology changed societies. This is true in the developed economies of North America and Europe as well as in the developing nations of the world. It is in the latter, the automobile is arguably of even greater benefit to society, playing a key role in helping economies start up the difficult road toward prosperity and an improved quality of life.
And once society has achieved value it won’t easy let go of it! However, alongside these benefits, we also have to witness the emergence of global environmental issues such as global warming and the dwindling of natural resources since the latter half of the 20th century until today. It is an undeniable fact that the automobile has been one of the elements inflicting environmental impact on the earth besides industry. Since society cannot or is not willing to step back, we must strive by all means to achieve a harmonious balance on earth. A greener car is a better idea. It is a new twist on familiar technologies, like gasoline and diesel power. Moreover, it is new technologies – like fuel cell and hybrid. Nevertheless, it is not easy to achieve this. Automakers made progress in reducing tailpipe emissions and making vehicles cleaner, supporting standards for cleaner fuel, increasing vehicles safety features, improving fuel efficiency and diversity, and building vehicles with less production waste and higher levels of recycling, but nevertheless the motor vehicle industry is facing a period of change and challenge.
Global consolidation and alliances among companies continue to occur.
Companies are fiercely competing for business and on environmental, vehicle safety and energy efficiency advances.
Technological advances are occurring at a faster pace than ever before.
Regulatory hurdles are set higher and higher.
Partnerships with government and allies flourish.
Consumers are demanding new features and enhanced performance as they choose new vehicles.

Excerpt from the Book
3.1.4 Technical Analysis of ‘Fuel Cell Powered Electrical Vehicles’
Originally developed for the space program, the fuel cell is the primary alternative to all batteries for supplying power to an electric vehicle's motor. Although a fuel cell looks like a battery, the former uses hydrogen or methanol fuel to continuously produce electric currents.
There are several kinds of fuel cells, but Proton Exchange Membrane (PEM) fuel cells are the type typically used in automobiles. A PEM fuel cell uses hydrogen fuel and oxygen from the air to produce electricity. The hydrogen, however, can be supplied in several ways.
FCVs can be fueled with pure hydrogen gas stored in onboard fuel tanks. Since hydrogen gas is diffuse, it must be stored in high-pressure tanks in order to store enough to travel reasonable distances on a full tank of fuel.
Currently used tanks, which allow hydrogen to be compressed to 5,000 pounds/square inch (psi) of pressure, can only store enough hydrogen gas to allow FCVs to go about 320 km before refueling. However, manufacturers are designing and testing tanks that will store more hydrogen at a higher pressure.
Summary of Chapters
1. Introduction: This chapter outlines the historical importance of the automobile and highlights the growing global environmental crisis that necessitates a transition toward greener vehicle technologies.
2. Early dominant design engines: This section provides an overview of the technical history of internal combustion engines, focusing on the development and limitations of the Four-Stroke Otto, Diesel, and Wankel engines.
3. Current Environmental Vehicles: This chapter offers a comprehensive technical analysis of electrical vehicles, alternative fuel vehicles, and hybrid systems, while examining the challenges regarding fuel availability, infrastructure, and international market acceptance.
4. Paradigm shift needed - how automakers can help: This chapter argues that achieving a shift toward sustainable mobility requires more than technical innovation; it requires addressing social factors, consumer psychology, and fostering public-private partnerships.
5. Conclusions: This chapter summarizes the industry's trade-offs and predicts that while hybrid technologies currently lead in consumer acceptance, fuel cells are likely to become the dominant design in the long term.
