Non-alcoholic fatty liver disease(NAFLD)and type 2 diabetes mellitus(T2DM)are two disease conditions for which obesity is a risk factor.^(1)Due to the close relationship between the three pathologies,researchers frequently use the same mouse models to identify the underlying processes of obesity,NAFLD,and *** instance,leptin(Lep)-null(ob/ob)and leptin receptor(Lepr)-deficient(db/db)mice spontaneously develop NAFLD and show different phenotypes of extreme obesity and diabetes,respectively.

BLEND MEMBRANES FOR DIRECT METHANOL AND PROTON EXCHANGE MEMBRANE FUEL CELLS

引用

Chinese Journal of Polymer Science 2012年第4期30卷 548-560页

作者： perumal Bhavani Dharmalingam Sangeetha Department of Chemistry Anna UniversityChennai 25India

Sulphonated polystyrene ethylene butylene polystyrene （SPSEBS） prepared with 35% sulphonation was found to be highly elastic and enlarged up to 300%-400% of its initial length. It absorbed over 110% of water by weight. A major drawback of this membrane is its poor mechanical properties which are not adequate for use as polymer electrolytes in fuel cells. To overcome this, SPSEBS was blended with poly（vinylidene fluoride）（PVDF）, a hydrophobic polymer. The blend membranes showed better mechanical properties than the base polymer. The effect of PVDF content on water uptake, ion exchange capacity and proton conductivity of the blend membranes was investigated. This paper presents the results of recent studies applied to develop an optimized in-house membrane electrode assembly （MEA） preparation technique combining catalyst ink spraying and assembly hot pressing. Easy steps were chosen in this preparation technique in order to simplify the method, aiming at cost reduction. The open circuit voltage for the cell with SPSEBS is 0.980 V which is higher compared to that of the cell with Nation 117 （0.790 V）. From this study, it is concluded that a polymer electrolyte membrane suitable for proton exchange membrane fuel cell （PEMFC） and direct methanol fuel cell （DMFC） application can be obtained by blending SPSEBS and PVDF in appropriate proportions. The methanol permeability and selectivity showed a strong influence on DMFC performance.
