... of reactants over carbon porous electrode (CPE) was controlled by modifying its pore structure with Teflon impregnation, and the effects of the Teflon on crossover, kinetic, Ohmic, and mass transfer was investigated by cell-based test and one-dimensional computational model. It was found that the cell...

... with reasonable agreement and used to study the effects of cell temperature, channel depth, and channel width on polarization curve, power density and crossover rate. The results show that the increasing operational temperature, the limiting current density and peak of power density increase and subsequently...

...Guo-Bin Jung; Ay Su; Cheng-Hsin Tu; Fang-Bor Weng Methanol crossover largely affects the efficiency of power generation in the direct methanol fuel cell. As the methanol crosses over through the membrane, the methanol oxidizes at the cathode, resulting in low fuel utilization and in a serious...
