The performance of high-temperature PEM fuel cell (HT-PEMFC) issubstantially influenced by physical parameters. In this work, theeffects of three parameters on the performance of HT-PEMFC are studied byusing a 3D model in COMSOL. The parameters are the operating temperature,membrane's thickness and catalyst layer's thickness. The polarizationcurves are adopted to analyze the effects on the performance. The resultsshow that the increase of temperature can enhance the performance of fuelcell. For the effect of catalyst layer thickness, the cell performance ispromoted as the catalyst layer's thickness decreases. For the effect ofthe thickness of membrane, it is found that the thinner membrane of fuelcell can achieve better performance. These findings can be furtherextended to guide the operation and design of HT-PEMFC in practicalapplications.
