Abstract: In order to solve the problem that liquid water accumulates at the corner and end of the flow channel of the PEMFC cathode flow channel in the serpentine flow field, a three-dimensional steady-state non-isothermal serpentine flow field PEMFC model with sub-channel was established by using the fluid dynamics software FLUENT. The effects of sub-channel inlet positions and flow rates on the performance of PEMFC were analyzed when the total amount of oxygen was kept constant. The results show that the sub-channel design can significantly improve the water management and mass transfer capacity of PEMFC, and the performance is optimal when the sub-channel inlet positions is 10 % and the flow rates is 70 %, and the maximum power density is 21.1 % higher than the traditional design.
