Indeed, hydrogen is the most abundant element in our universe and carries the most energy per
unit of weight. This carbon-free fuel can be produced either using traditional or renewable power
sources such as solar or wind power. Once captured, hydrogen can be converted back to usable
energy in numerous applications, including cars. This means our every day fuel can be produced
locally, and in unlimited quantities. When it is consumed in the fuel cell, the result is electricity and
water. This water can then be used to produce hydrogen and oxygen, making the cycle is
continuous and natural, with no toxic emissions. There are many challenges to making this a
reality, but it's only a matter of time... ...and human ingenuity!

Around the world, several “Hydrogen Highway” projects are being developed and over 200
hydrogen refueling stations have already been built to service the first fuel cell cars.

b. What is a fuel cell and how does it work?
A fuel cell is a device that can convert hydrogen to usable electric power. The fuel cell is an
assembly of advanced material layers where hydrogen and oxygen react with each other to
generate electricity and water, without any combustion.

Serious interest in fuel cells did not begin until the 1960's, when they were used as power for
mans first missions to the moon. Although fuel cells still provide electricity and water for today's
space missions, this unique technology is now aimed at promoting a global transition to
renewable energy sources. Fuel cell cars that use hydrogen as fuel are called "zero emission
vehicles." If fuel cell cars were to use hydrogen produced by renewable sources of energy such
as solar or wind power, our fuel supply would be unlimited - and consumption of hydrogen
through fuel cells would not create any waste nor air pollution.
