This study involves the meticulous design of a reliable standalone multi-vector hybrid energy configuration comprising photovoltaic panels, wind turbines, and fuel cells (PV/WT/FC) for stochastic electric vehicle (EV) load. Significantly, the research presents a pioneering methodology that incorporates chaotic particle swarm optimization aligned with the Andean Condor algorithm (CPSO-ACA), providing a sophisticated optimization approach. The evaluation process is based on key measures like net present cost (NPC), levelized cost of energy (LCOE), and reliability indicators such as loss of load probability (LOLP), loss of load expectation (LOLE), and loss of energy expected (LOEE). With the proposed hybrid approach, a reliable hybrid energy system with the lowest renewable energy components and promising reliability (LOLP = 0.064) has been reported. From a financial perspective, the values of NPC, LCOE, and LOE ($4.06 M, $0.0636/kWh, and $0.7083 M) enable the hybrid system to be economically sound. Furthermore, the energy-oriented reliability indices, LOEE and LOLE, have significantly reduced to 5920 kWh and 564.144 h, respectively. The effectiveness of the proposed algorithm is compared with GA, GWO, MOPSO, and CPSO algorithms and is indicative of the strength achieved through proposed optimization in the evolving landscape of green energy technology.</p>\u0000 </div>","PeriodicalId":12566,"journal":{"name":"Fuel Cells","volume":"25 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144672892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate mathematical modeling of PEMFCs is essential for their simulation, evaluation, optimization, and effective management. This study introduces a newly developed metaheuristic algorithm, the Horned Lizard Defense Tactics Optimization Algorithm (HLDTOA), for parameter identification in PEMFC mathematical models, leveraging semi-empirical equations to enhance precision. The HLDTOA is applied to determine the unknown design parameters of various PEMFCs under diverse operating conditions of pressure and temperature.

Statistical analyses further demonstrate the robustness and superiority of HLDTOA. The high correlation between derived and experimentally measured <i>I</i>–<i>V</i> polarization curves underscores its precision and reliability. Additionally, the dynamic characteristics of PEMFCs are evaluated to test the optimized parameters under varying reactant pressures and cell temperatures.

This is particularly important for applications that frequently experience high-load conditions, where power usage and heat production are high. However, the impact of these temperatures on the degradation of membrane electrode assemblies (MEAs) is not well understood. Here, we show performance degradation of four automotive type MEAs at 80°C, 100°C, and 120°C, studied using electrochemical characterization and electron microscopy. Higher operating temperatures leads to increased performance degradation, increased Pt growth and larger electrochemical surface area (ECSA) losses for all samples. However, neither ECSA losses nor increased resistance are sufficient to explain the severe performance loss observed for most samples at 120°C.

The results indicated that increasing the operating temperature and the anode inlet Reynolds number could enhance the output power density of the SOFC, whereas the temperature gradient within the SOFC also increased accordingly. The enhancement of these parameters led to an increase in the electrical performance (characterized by power density) of the SOFC while concurrently diminishing its thermal performance (characterized by temperature gradient). Under the same conditions, the SOFC with a zigzag channel exhibited superior electrical performance compared to the SOFC with a conventional parallel channel, albeit with slightly inferior thermal performance.
