Review on the development of fuel cells and its future prospects

Fossil fuels are unsustainable energy storage medium with pollution problems. With the limitation of fossil fuels, fuel cells, which are known as effective electrochemical converters, has attracted much attention. Present review paper provides a complete information on fuel cell technology and history which includes competing technologies, current status of research-and-development and its future direction. Fuel cell plays an important role in stationary applications from 1990s till now due to its efficiency upon reducing emissions.
