Anode materials for sediment microbial fuel cells.
INTRODUCTION Plant microbial fuel cells (P-MFCs), and more general sediment microbial fuel cells, make use of electricigenic metabolism of microorganisms in anoxic soils and sediments. Electricigenic microorganisms are able to respire organic carbon from the soil or sediment with an electrode as final electron acceptor [1]. In this work, the focus is on the anode buried in the sediment, the ele...
متن کاملMaterials for Solid Oxide Fuel Cells
Solid oxide fuel cells (SOFCs) have the promise to improve energy efficiency and to provide society with a clean energy producing technology. The high temperature of operation (500-1000 C) enables the solid oxide fuel cell to operate with existing fossil fuels and to be efficiently coupled with turbines to give very high efficiency conversion of fuels to electricity. Solid oxide fuel cells are ...
متن کاملNafion Nanofiber Composite Membrane Fabrication for Fuel Cell Applications
A proton exchange membrane has been developed for direct methanol fuel cell (DMFC). The nanofiber network composite membranes were prepared by interconnected network of Nafion (perfuorosulfonic acid) nanofibers that have been embedded in an uncharged and inert polymer matrix, by electro-spinning. The spinning solution of Nafion with a low concentration (1 wt% compared to Nafion) of high molecul...
متن کاملMechanical Properties of Nafion and Titania/Nafion Composite Membranes for Polymer Electrolyte Membrane Fuel Cells
Measurements of the mechanical and electrical properties of Nafion and Nafion/titania composite membranes in constrained environments are reported. The elastic and plastic deformation of Nafion-based materials decreases with both the temperature and water content. Nafion/titania composites have slightly higher elastic moduli. The composite membranes exhibit less strain hardening than Nafion. Co...
متن کاملNafion-Bimevox Composite Membrane for Fuel Cell Applications
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...
