A REVIEW ARTICLE ON FUEL CELL

Abstract

A fuel cell is a device that uses hydrogen (or hydrogen-rich fuel) and oxygen to create electrochemical process. If pure hydrogen is used as a fuel, fuel cells emit only heat and water as a by product. Several fuel cell types are under development, and they have a variety of potential applications. oped to power passenger vehicles, commercial buildings, homes, and even small rich fuel) and oxygen to create electricity by an electrochemical process.
