Gas transport in the porous electrode plays a crucial role in the performance of fuel cells. Inthis work, gas convection caused by temperature gradient, typically ignored in the analysis of gastransport in fuel cells, has been evaluated quantitatively. The correlation of gas convection with gas pressure and electrode thickness is investigated systematically. In addition, limiting current density loss...
A composite anode material of silicon/graphite/multi-walled carbon nanotubes (MWNTs) for Li-ion batteries was prepared by ball milling. This composite anode material showed a discharge capacity of 2274mAh/g in the first cycle, and after 20 charge–discharge cycles, a reversible capacity of 584mAh/g was retained, much higher than 218mAh/g for silicon/graphite composite. It was observed that silicon...
