http://bit.ly/cYZEjr Fuel cells run on hydrogen (hidrogen fuel), the simplest element and most plentiful gas in the universe. Hydrogen is colorless, odorless and tasteless. Each hydrogen molecule has two atoms of hydrogen, which accounts for the H 2 we often see. Hydrogen is the lightest element, with a density of 0.08988 grams per liter at standard pressure, yet it has the highest energy content per unit weight of all the fuels (hidrogen fuel) 52,000 Btu/lb, or three times the energy of a pound of gasoline.
Hydrogen is never found alone on earth — it is always combined with other elements such as oxygen and carbon. Hydrogen can be extracted from virtually any hydrogen compound and is the ultimate clean energy carrier. It is safe to manufacture. And hydrogen's chemical (hidrogen fuel) energy can be harnessed in pollution-free ways.
Hydrogen (hidrogen fuel) generated from diverse domestic resources can reduce demand for oil by more than 11 million barrels per day by the year 2040.
A good source of information on hydrogen is the U.S. Department of Energy's H2IQ web page, as well as the overview book, Hydrogen & Our Energy Future, which expands on DOE's series of one-page fact sheets to provide an in-depth look at hydrogen (hidrogen fuel) and fuel cell technologies. This overview book provides additional information on the science behind the technology — how it works, benefits over conventional technology, its status, and challenges — and explains how hydrogen and fuel cells (hidrogen fuel) fit into our energy portfolio.
