Hydrogen The Future Energy Sources For Fuel

Burned or used in fuel cells, hydrogen is an appealing option for powering future automobiles. This nontoxic gas could serve as a pollution-free energy carrier for machines of many kinds. When it burns, it releases no carbon .dioxide, a potent greenhouse gas.
 And if hydrogen is fed into a fuel cell stack a battery like device that generates electricity from hydrogen and oxygen it can propel an electric car or truck with only heat and water as by products. Fuel-cell powered vehicles could offer more than twice the efficiency of today's automobiles. Hydrogen could, therefore, help ease environmental problems, including air pollution and its hazards.
