Abstract | This paper proposes a novel reaction device design for micro direct methanol fuel cell (muDMFC) with the combination of micro and nano structures for the enhancement of reaction area. The device combined micro porous Si thin film by DRIE with the growth of high-aspect-ratio carbon nanotubes (CNTs) with specific direction on the vertical sidewall surfaces of micro holes to increase the reaction area by 3-4 orders. By the loading of Pt nanoparticles on CNTs, this device would be applied to the anode or cathode in muDMFC. SEM clearly showed well controlled 100~150-mum-deep micro holes with CNTs growth on the sidewall with the diameter of 80~100 nm and length of 3~5 mum. It is suggested that the reaction performance can be improved by orders of magnitude when both the micro structures and CNTs combine together. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
