| Abstract | Thermal and water management procedures in proton exchange membrane (PEM) fuel cells that influence stack performance are described. The characteristics of ion exchange membranes, mass and heat transfer effects, and thermal effects are discussed. Various design options for successful PEM stack operation are proposed. Humidification strategies result in opportunities both for thermal control and for maintenance of appropriate ionic conductivity throughout active cell areas. Dehydration of anode gases can be altered by two approaches: increased water permeability within the polymer or repeated humidification by the introduction of additional water, perhaps as a supersaturated feed, or as the result of additional sequential humidification along the utilization path. The results predict that high-current-density, stable performance is feasible for a variety of different PEM options including hydrogen-oxygen, hydrogen-air and reformate-air.< |

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.
