| Abstract | This research is to fabricate μ-DMFC (micro direct methanol fuel cell) by using MEMS technology. A novel concept of design, compared with the traditional type of DMFC, has been designed and fabricated, which anode and cathode are made in the same plane so called coplanar type of DMFC. In this coplanar type of DMFC, we can also integrate the current collectors and catalyst layer on the flow channels. In order to improve the performance of entire system, we also integrate the fuel preheat device on the chip, so heater was put on the flow channels. By the heating effect, we apply voltage on both sides to increase operation temperature. The experiment results show that when we apply 41 volts on the pads, system average temperature will reach 70°C. Then the fuel (2M CH3OH / 2.5M H2SO4 / H2O) was fed into anode, and (O2-sat. / 2.5M H2SO4 / H2O) was fed into cathode, operating under 70°C. The maximum power was reached around 0.956mW/cm2 at 4.978 mA/cm2. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
