A REVIEW ON HYDROGEN: THE FUTUREFUEL

Abstract

Present paper deals with the use of hydrogen as fuel and with its future aspects too. Due to increase in dependency in non-renewable energy resources, there has been studies and interest in using a cleaner and more eco-friendly approach to consuming energy and one such approach is hydrogen fuel, combination of oxygen from air and water through electricity produces hydrogen fuel cell. Hydrogen can be produced by variety of technologies, such as chemical, biologic, electrolytic, and photolytic. Hydrogen can be produced from methods like gasification, electrolysis, and hydrogen fuel cells etc. Hydrogen fuel cells functions best with the help of proton exchange membranes fuel cells (PEMFC). PEMFC is type of fuel cell being developed mainly for transport applications, as well as for stationary fuel cell application. Their distinguishing features include lower temperature/ pressure ranges (50 to 100 C) and a special proton conducting polymer electrolyte membrane. The major application of polymer electrolyte membrane fuel cells focuses on transportation primarily because of their potential impact on the environment e.g. the control of emission of the greenhouse gases.
