Abstract |
A two-dimensional, steady state, nonisothermal, nonequilibrium, multifluid, two-phase flow model is employed to investigate fuel delivery characteristics, as well as the strong relation between water transport through the membrane and methanol crossover. A porous layer, called the fuel delivery layer, is used between the anode backing layer and the methanol reservoir to be able to employ high concentration methanol solution at the anode reservoir. A simple analytical model for liquid methanol distribution in the anode is presented to show the significant effect of water crossover through the membrane on the methanol dilution at the anode catalyst layer....
