Much as it has contributed to extraordinary mobility for many people, countries to rely heavily on oil from politically unstable regions, and intensified the long-term threat to global warming. It seems possible that some time in the next decade, auto-manufacturers will be ready to market new, super energy-efficient cars powered by fuel cells that drive powerful, high-torque electric motors. Such vehicles will produce virtually no polluting gases such as carbon dioxide, which contributes to the greenhouse effect, or oxides of nitrogen or sulphur that are the main causes of acid rain. They can be fuelled by hydrogen from a variety of secure energy sources. The development of fuel cell depends on a detailed understanding of one of the simplest chemical...
