    Abstract:To study the hydrothermal characteristics inside an air-cooled proton exchange membrane fuel cell （PEMFC） and improve the uniformity of physical properties such as water and heat within the cell， a multi-inlet anode method was proposed. Based on the single-channel serpentine flow field inlet method， four different inlet methods were presented， and a three-dimensional model was established for computational analysis. The results showed that under a voltage of 0.635 V， using the multi-inlet method could enhance the output performance of the PEMFC， improve the uniformity of membrane current density， membrane water content， anode catalyst layer hydrogen content， and anode catalyst layer water content， but the temperature uniformity was poor with the same-side inlet method.
