“…Consequently, the ultimate determination of diverse parameters is inherently complex. The main research factors currently include operating temperature [27], operating pressure [28], relative humidity [29], doping level [30], thickness of membrane [31], and Pt loading [32]. Thus, a significant obstacle arises in the optimization process of the HT-PEMFC: conducting a comprehensive assessment encompassing various factor groups is unrealistic.…”

The design and operational conditions of high-temperature proton exchange membrane fuel cells (HT-PEMFCs) substantially impact their performance. This model aims to investigate the influence of various parameters on the performance of HT-PEMFC. A comprehensive examination revealed that the performance of HT-PEMFC experienced a significant enhancement through modifications to the operating temperature, doping levels, and membrane thickness. Significantly, it can be observed that operating pressure showed a limited influence on performance. The HT-PEMFC was optimized using the non-dominated sorting genetic algorithm II (NSGA-II), specifically emphasizing three primary performance indicators: equivalent power density, energy efficiency, and exergy efficiency. The findings demonstrate promising outcomes, as they reveal a noteworthy enhancement in power density by 17.72% and improvements in energy efficiency and exergy efficiency by 21.11% and 10.37%, respectively, compared to the baseline case.

“…Among the existing Li-ion batteries on the market, LTO enjoys the highest performance, lifespan, and safety at higher cost, whereas NMC provides acceptable performance with low cost and high specific energy [30]. In comparison to the batteries, proton-exchange membrane fuel cells (PEMFCs) have faster refueling times and higher ranges [31]; hence, the integration of batteries and fuel cells can address the needs of UAVs.…”

The harmful impacts of fossil-fuel-based engines on the environment have resulted in the development of other alternatives for different types of vehicles. Currently, batteries and fuel cells are being used in the automotive industry, while promising progress in the maritime and aerospace sectors is foreseen. As a case study in the aerospace sector, an unmanned aerial vehicle (UAV) was considered. The goal and the novelty of this study are in its analysis of the possibility of providing 960 W of power for a UAV with a weight of 14 kg using a hybrid system of a lithium-ion (Li-ion) battery and proton-exchange membrane fuel cell (PEMFC). The dynamic performance of the system was analyzed considering three different load profiles over time in an optimized condition. PEMFC was the main supplier of power, while the battery intervened when the power load was high for the PEMFC and the system demanded an immediate response to the changes in power load. Additionally, the impacts of the operating temperature and the C-rate of the battery were characterized by the state of the charge of the battery to better indicate the overall performance of the system.

“…Li et al [ 34 ] established a HT-PEMFC model of vehicle application in ADVISOR and the results showed that increasing the operating temperature can significantly improve the performance of HT-PEMFCs. Bayat et al [ 35 ] pointed out that increasing the relative humidity contributes to an increase of 8.02% and 8.03% in energy and exergy efficiency. Yang et al found that increasing the phosphoric acid content in the membrane would improve the proton conductivity.…”

In order to improve the output performance of high-temperature proton exchange membrane fuel cells (HT-PEMFC), a finite time thermodynamic (FTT) model for HT-PEMFC was established. Several finite time thermodynamic indexes including power density, thermodynamic efficiency, exergy efficiency, exergetic performance efficient (EPC), entropy production rate and ecological coefficient of performance (ECOP) were derived. The energetic performance, exergetic performance and ecological performance of the HT-PEMFC were analyzed under different parameters. Results showed that operating temperature, doping level and thickness of membrane had a significant effect on the performance of HT-PEMFC and the power density increased by 58%, 31.1% and 44.9%, respectively. When the doping level reached 8, the output performance of HT-PEMFC wa optimal. The operating pressure and relative humidity had little influence on the HT-PEMFC and the power density increased by 8.7%% and 17.6%, respectively.
