Benefits of using carbon nanotubes in fuel cells: a review

A carbon nanotube (CNT) is a nanoscale cylindrical tube formed from a single atomic layer of carbon atoms. CNTs are known to possess several unique characteristics, including high thermal and electrical conductivity, superior mechanical strength and chemical stability, as well as a high surface area. These characteristics, in addition to the fundamental advantages of being a carbon material, cause CNTs to be a favorable candidate for fuel cell applications. In this current assessment, past findings in relation to CNTs are summarized. Additionally, future prospects for microscopic study of CNTs are also presented
