Abstract :
It has been investigated how to enhance the performance of a High-Temperature Proton Exchange Membrane Fuel Cell (HT-PEMFC). The catalytic layer (CL) combination and external temperature control were both put to the test. The optimal CL combination was determined using the CL's structures, characteristics, binder, and platinum/carbon (Pt/C) concentration as perimeters. The thickest CL has the smallest size and most even distribution of Pt catalyst when the lowest weight percentage of Pt/C is used. As a result, the electrochemical reaction is likely to occur. A higher gas permeability is provided by the Polytetrafluoroethylene (PTFE) binder, allowing more gases to diffuse to the working region. The highest power density of 190.15 mW/cm2 at 0.3067 V and the highest current density of 0.62 A/cm2 were both attained. The optimum CL combination is 10 wt% Pt/C.
