The fuel cell has the nature of high energy conversion efficiency and low pollutant emission. Carbon nanotubes used for fuel cells can decrease the needs of noble metals which are used for catalyst and improve the performance of fuel cells. The application of carbon nanotubes in fuel cells is summarized and discussed. The following aspects are described in this paper: the method used to reduce the platinum, the effect of carbon nanotubes on the fuel cell, improving the performance of fuel cell catalysts, the interaction between catalyst and carbon nanotube support, and the synthetic conditions of carbon nanotube supported catalyst. We summarize some of the results of previous studies and raise expectations for the microscopic state study of carbon nanotubes in the future.

Diversity Measurement

Fuel cells having a high energy conversion efficiency with low restriction of installation space is rising as a new eco-friendly renewable energy source. Fuel cells are largely divided into MCFC, SOFC, PEMFC, DMFC, etc. according to the type to be transferred. In this study the four fields were analyzed from a diversity aspect, a social network aspect and a distance aspect. Results showed PEMFC and MCFC to apply the most diverse technology, and catalyst technology and hydrogen fuel manufacturing areas were observed developing in all four fields. In addition, many studies were found to be commonly conducted for fuel cell vehicles in the PEMFC and SOFC fields. PEMFC is expected to have the highest effect with technology development, specifically commercialization of the Fuel Cell Vehicles through an active technology development. Development in the SOFC and MCFC fields are expected to promote home fuel cell use.
