Optimizing the structural characteristics of the PTL is important for enhancing the overall performance of PEMWE. In this study, a three-dimensional steady-state PEMWE model is firstly developed. Based on the model, polarization curves of the PEMWE under different PTL parameters are computed, and the impacts of three characteristic parameters, i.e. porosity, thickness, and conductivity, on the PEMWE performance are thoroughly investigated. Then, the corresponding performance optimization strategies are proposed by incorporating a multilayer perceptron (MLP) machine learning model. It shows that porosity plays a dominant role in the PTL performance among the three parameters, followed by thickness, with conductivity having a relatively minor impact. The increasing of porosity and reducing of thickness can effectively enhance the electrolyzer performance. According to the MLP model screening, the optimal PTL structure is determined to be the porosity of 0.52, thickness of 0.2 mm, and conductivity of 4×10<sup>6</sup> S/m.
