| چکیده مقاله |
| Nowadays, the production of carbon-based nonprecious metal electrocatalysts (NPMCs) by using metal-organic frameworks (MOFs) as precursors has attracted much attention [1-3]. On the other hand, considering the significant effects of different operating conditions on the performance, efficiency, and durability of polymer electrolyte membrane fuel cells (PEMFCs), studying the effects of operating temperature on electrochemical reactions kinetics, membrane proton conductivity, and water management and optimizing that is very important [4-6]. In this study to investigate and optimize the operating temperature, two membrane-electrode assemblies (MEAs) were fabricated according to a specific method, in the first sample (MEA 1) similar to commercial systems, platinum electrocatalyst (Pt/C) was used, and in the second sample (MEA 2) for the oxygen reduction reaction (ORR) in the cathode, the nonprecious metal electrocatalyst (Fe/Co-N-C) which obtained by using Fe/Co-ZIF-8-(10 h) MOF precursor was used [7]. The performance of both samples was examined in the same way under different operating temperatures (65 °C, 70 °C, 75 °C and 80 °C) in a single cell by the fuel cell test station (BioLogic FCT-150S) and electrochemical tests. Based on the obtained results, the optimal operating temperature of MEA 1 and MEA 2 is 75 °C, where the maximum power density of 822 mW/cm2 and 266 mW/cm2 was obtained respectively. |
