Simulation of Mass Transfer in Anode Flow Field of a Passive Direct Methanol Fuel Cell

Abstract:

A three-dimensional model for anode side of a passive direct methanol fuel cell with perforated flow field was developed to investigate the mass transfer in anode flow channels. The model simulated the transient two-phase flow in channels. With this model, the distribution of methanol concentration and carbon dioxide volume fraction in channels was presented. The variation of species on the central surface of flow channels was also gained. Simulation results show that the mass transfer in anode flow field of passive direct methonal fuel cells is affected by comprehensive effects of diffusion and convection. The results also indicate that the methanol transfer in channels is influenced by the carbon dioxide.
