Hydrogen fuel cells have been considered an alternative for a clean source of energy. In a fuel cell, hydrogen reacts with oxygen to produce water, and at the same time, it releases a great deal of energy. Write an essay that addresses the chemical reaction of hydrogen fuel cells, the energy that is available from this reaction, and whether this type of alternative fuel is feasible. Be complete and use examples to support your statements.
