INTRODUCTION A fuel cell by definition is an electric cell, which unlike storage cells can be continuously fed with the fuel so that the electrical power output is sustained indefinitely. It converts the hydrogen or hydrogen containing fuels directly into electrical energy plus heat through the electrochemical reaction of a hydrogen and oxygen into water. Fuel cells are one of the cleanest and most efficient technologies for generating electricity. A fuel cell produces electricity by means of an electrochemical reaction much like a battery. But there is an important difference. Rather than extracting the chemical reactants from the plates inside the cells, a fuel cell uses hydrogen fuel and oxygen extracted from the air to produce electricity. Unlike a battery, however, fuel cells never lose their charge. As long as there is a constant source of fuel - usually natural gas for the hydrogen and air for the oxygen -...
