Structure of anode flow field is very important for micro direct methanol fuel cell.To optimize the structure of the anode flow field and the distribution of methanol in it
a model of micro direct methanol fuel cell is created and analyzed by using the computational fluid dynamics(CFD) software.The influence of flow field shapes of grid
parallel and serpentine are analyzed and the pressure drop and velocity distribution in the three kinds of flow fields are studied.It shows that the flow field of serpentine is the best for the even distribution of fuel.Based on this
serpentine flow field models with different width(800
400
200 and 100 μm) are created.Simulations are taken to analyze the influence of distribution to cell perf
ormance and compared with experimental results
it shows that the optimal value of flow channel width is 200
4
00 μm.
