| Abstract: | The conventional parallel flow field of the proton exchange membrane fuel cells have problems with poor mass transfer,and large amounts of liquid water cannot be discharged in time at high current density,resulting in a sharp drop in performance.A novel wave parallel flow field is proposed and the geometric structure of the wave parallel flow field is optimized by numerical simulation method.The results show that compared to the conventional parallel flow field,the wave parallel flow field can not only effectively promote the transmission of oxygen,but also accelerate the removal of liquid water.The maximum output power of the PEMFC with the wave parallel flow field is increased by 30.7%compared with the conventional design,and the performance of PEMFC with the novel flow field is optimal when the wave length and amplitude are 4 mm and 0.8 mm,respectively. |
