For the last decade, dimethyl ether (DME) has been considered a promising alternative fuel for direct fuel cells because of several advantages over methanol. In this work, PtRu catalysts with a wide range of Pt-to-Ru ratios were screened for the direct DME fuel cell (DDMEFC) performance for the first time. Overall, Pt50Ru50 performs best in the high and middle voltage ranges, whereas Pt80Ru20 p...

We have proposed a unified approach to the modeling and study of developments in the field of MEMS and Nanotechnology and its application in futuristic Nano-enabled Cells. We have proposed a novel to approach reliability of MEMS enabled fuel cells. We know that reliability and accurate prediction of properties in nano domains remains a major challenge where still theories are being developed to...

Direct methanol fuel cells (DMFCs) are considered to be one of the most promising candidates for portable and stationary applications in the view of their advantages such as high energy density, easy manipulation, high efficiency and they operate with liquid fuel which could be used without requiring any fuel-processing units. Electrolyte membrane of DMFC plays a key role as a proton conductor ...

To suppress methanol crossover in direct methanol fuel cells DMFCs , a Nafion-Bi2V0.75Sb0.25O5.4 composite membrane was prepared by recast method. Oxygen-ion conductive Bi2V0.75Sb0.25O5.4 powders were highly dispersed in a Nafion 117 membrane to physically block methanol crossover and/or chemically oxidize the methanol, which was confirmed by the difference in the methanol diffusion coefficient...
