Abstract
Based on CFD (computational fluid dynamics), modeling and numerical simulation of the muDMFC (micro direct methanol fuel cell) are carried out ,meanwhile the influence of the muDMFC with various flow channels design is studied using the CFDRC commercial code. The simulation results show that the performance of the muDMFC with the parallel flow field excelled the one with the dot flow field. The experimental results show the same performance compared with the simulated data, and the muDMFC with parallel flow field has a maximum power density of 5.92mW/cm2 at the voltage of 192.9mV while the one with dot flow field has a maximum power density of 4.37mW/cm2 at the voltage of 180.7mV.
