| Abstract | Polymer electrolyte membranes used in fuel cells are proton selective and hence allows only protons to pass through it. The electrolyte composition, morphology and water absorption properties of the membrane greatly influence the performance of the fuel cell. For example the membranes used in fuel cells should meet following requirements. • Good thermal stability above 250°C. • Proton conductivity greater than 10^-2 S/cm. • Good water absorption and water retaining capacity. • mechanical strength and flexibility. The present paper is focused on design and development of a membrane suitable for fuel cell application. The base polymer chosen in this present work has been thermoplastic polyurethane because of its high flexibility, temperature resistance and solubility in organic solvent such as DMF. Fabrication of the coating machine was done and thermoplastic polyurethane (TPU) based Composite membranes with an average thickness of 40 microns were cast. Sulphonation of polystyrene was carried out to get SPS with assay 98%. TPU based composite membranes with conducting resins of 25% SPEEK, 4%SPS and 10% PANI were cast and characterized by FTIR, DSC, four probe conductivity and SEM. The composite membranes were studied for fuel cell suitability. The studies show that a current in the range of 0.5×10−4 A to 0.8344×10−4 A and about 0.5V can be drawn out of these membranes. The results were compared with that of NAFION membrane. |

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.
