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.
