The Platinum catalyst degradation is largely affected by the upper limit of voltage cycling potential (UPL) and operating temperature of the proton exchange membrane fuel cell (PEMFC). This study integrated a physics-based 1D sub-model for Pt degradation and a 100 cm 3D fuel cell performance model. A quantitative analysis was conducted to assess the performance degradation of PEMFC with two different Pt loadings, one with a loading of 0.3 mg/cm and the other with a loading of 0.05 mg/cm, undergoing 15,000 voltage cycles at various cycling UPLs and operating temperatures. The simulation results indicate a significant drop in performance for the PEMFC with a Pt loading of 0.05 mg/cm at a voltage cycling UPL of 1.0 V. Furthermore, it can be shown that the 0.05 mg/cm Pt loading PEMFC experiences a higher extent of performance degradation compared to the 0.3 mg/cm Pt loading PEMFC when the operating temperature approaches 90 °C.
