role of nanotechnology in fuel cells and renewable energy

ABSTRACT

Nanotechnology deals with the study and manipulation of matter at minute scales of the order of less than 1mm in length, and is a leading research topic among scientists and engineers. This study discusses the contributions that nanotechnology has to offer in the context of renewable energy. Focus is mainly on improvements in efficiency, feasibility and supply of renewable energy resources. Specific emphasis is placed on hydrogen technologies. Considerable growth is being witnessed in the rene- wable energy industry. Climate change, triggered by greenhouse gas emissions, and consequent changes in public opinion, and pressure have all resulted in renewed interest in renewable energy sources. Only certain specific areas of renewable energy technologies, such as material strength and its physical properties, are influenced by nanotechnology as there are no alternative means of achieving the desired thermochemical/electrochemical efficiencies than through the use of nano-scale technologies
