Fuel Cell Technologies and Applications

This paper provides a review of the various technologies of fuel cells based on the publications throughout the past century. It also highlights the various applications of the fuel cell technology in day to day life resulting in the development of a viable option to the existing energy production techniques. As a clean fuel is used in the fuel cell technology to produce electricity, it results in almost zero emissions, thus being environment friendly and also offering high efficiencies and a constant source of power. Although the fuel cell technology seems to be an impressive alternative to the traditional technologies, certain challenges hinder the commercialization of this technology which have also been discussed in this review. Thus a lot of R&D needs to go into this technology until it becomes a large scale reality.
