Three-dimensional, two-phase, CFD model for the design of a direct methanol fuel cell

Numerical Investigations of the Combined Effects of Flow Rate and Methanol Concentration on DMFC Performance

“…The crossover terms of methanol and water can be defined as [17,21] 3 OH denotes the local methanol concentration at the interface between the catalyst layer and membrane surface, and t mem and t acl are the thicknesses of the membrane and catalyst layer, respectively. The local volumetric current density of the cell j a is defined by [15,18] …”

“…During the past decades, several mechanical models based on Computational Fluid Dynamics (CFD) techniques were proposed to study the energy conversion process of DMFC systems, from one-dimensional [11], two-dimensional [12,13] to three-dimensional (3D) [14][15][16][17][18][19] points of view.…”

Numerical analysis of electrochemical characteristics and heat/species transport for planar porous-electrode-supported SOFC

“…in the cell. However, the three-dimensional numerical simulation, based on commercial computational fluid dynamic (CFD) code and a user defined routine for dealing with electrochemical processes, can provides a better understanding of main phenomena that govern fuel cell performance [13], for example, the cell internal temperature and flow composition profiles, fuel and oxidant utilization, cell power output and cell voltage or current output.…”

Investigating design parameter effects on the methanol flux in the passive storage of a direct methanol fuel cell

“…The development of CFD modeling simulation did improve the design of DMFC as well as its performance. Danilov et al [13] built three dimensional two phase CFD model to focus on the flow field influence on DMFC performance. The information from CFD modeling and simulation helped them to increase the performance and better design of the flow field.…”
