Abstract

Direct methanol fuel cell (DMFC) is a technology that converts the chemical energy of methanol to electrical energy. Experiments on DMFC performance are costly and time consuming. Thus, computational fluid dynamics (CFD) simulations of DMFC were carried out in this study. The flow fields of parallel, serpentine, and zigzag were investigated to visualize the distributions of velocity, pressure, and methanol mole fraction at the anode and to study the DMFC performance. DMFC CFD simulations were conducted using ESI CFD-ACE+ software package that includes CFD-GEOM, CFD-ACE-GUI, and CFD-VIEW. The simulations were then validated by comparing the power density curve obtained from a literature review. Physical parameters and dimensions of the model were also determined based on a literature review. Results show that the flow field channels exhibited uniform distributions of velocity and methanol mole fraction, as well as high pressure drop and improved DMFC performance. The flow field channels with widths of 1.0, 1.5, and 2 mm were also investigated. The obtained results indicate that the serpentine flow field with a flow channel width of 2 mm showed the best performance of DMFC based on the distributions of velocity, pressure, and methanol mole fraction.
