Three-Dimensional Model and Experiment of New Flow Field for Proton Exchange Membrane Fuel Cell Using CFDRC (original) (raw)

This research is to study the gas distribution within the Proton Exchange Membrane Fuel Cell (PEMFC) that using the homebuilt developed flow field. This flow field combines curve header together with parallel-serpentine in order to extend the reaction area. A 3D numerical modeling of PEMFC was set up and solved by using commercial computational fluid dynamics (CFD) software, the "CFDRC ® ". The affect of gas flow field on the gas distribution caused by the chemical reaction inside the fuel cell were numerically studied. The result shows the developed flow field has the density of electric power about 81.25 mA/cm 2 and the conventional flow field fuel cell is about 69.22 mA/cm 2 which is better around 17.5%. From the test of developed fuel cell with the temperature and the flow rate, found that at the work in temperature; 50 o C and the flow rate at 150 sccm gave the best density of electric power.
