Fuel Cells-A Signpost to Future

Abstract

In a few decades, fuel cells have gained moreinterest as a zero emission source of energy. Fuel cells are intensive sources that extrude power from hydrogenand oxygen directly at low voltage. Fuel cells have passed demonstration stage, have been marketable because of the remarkable worldwide research and development. Fuel cells offer a promising alternative to conventional energy conversion technologies for a wide range of applications. Fuel cells can also be an interesting solution for many power sources. This paper presents an overview of different fuel cells and their applications emphasizing that fuel cells is a sign post to the future.
