The current collector offers passages for mass transport and is one of the key components of the passive direct methanol fuel cell (DMFC). The effect of perforated current collector design on mass transport is studied based on a three-dimensional (3D), unsteady-state, two-phase mass transport...

A one-dimensional, steady-state, two-phase direct methanol fuel cell (DMFC) model is developed to precisely investigate complex physiochemical phenomena inside DMFCs. In this model, two-phase species transport through the porous components of a DMFC is formulated based on Maxwell–Stefan...
