The simulations were run for 1800 s using the Worldwide Harmonized Light Vehicles Test Cycle (WLTC 3a), spanning a distance of 23 km, to assess important performance characteristics such as energy efficiency, consumption, emissions, and life cycle costs. The PFCEV architecture, which combines a medium-sized fuel cell and a sizable battery pack, has a strategic advantage because it requires fewer charging stations than BEVs and fewer hydrogen filling stations than FCEVs. The findings reveal that PFCEVs provide a unique combination of high efficiency, low emissions, rapid recharging, and greater driving range while requiring minimal hydrogen infrastructure. Compared to BEVs, PFCEVs minimize range anxiety while improving grid stability, and unlike FCEVs, they maximize hydrogen utilization via a complicated power management system. This study highlighted PFCEVs as a viable choice for sustainable mobility, serving as a valuable link between BEVs and FCEVs in the evolution of electric transportation. The findings indicate that PFCEVs have a good possibility of becoming a preferred vehicle technology, bridging the gap between battery and hydrogen-powered electric vehicles while addressing infrastructure and efficiency challenges.</p>\u0000 </div>","PeriodicalId":12566,"journal":{"name":"Fuel Cells","volume":"25 5","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224070","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}

In the pursuit of sustainability, proton exchange membrane fuel cells (PEMFCs) are considered a promising solution for optimizing the utilization of green hydrogen and enhancing energy storage capabilities. This article presents a novel application of the mirage search optimization (MSO) algorithm for developing an accurate PEMFC model. Through a comprehensive study of four typical PEMFC stacks, the results demonstrate the superior performance of the proposed MSO algorithm when compared to other optimizers in terms of accuracy and convergence speed. The optimization algorithms used for comparison with MSO include the grey wolf optimizer, whale optimization algorithm, chimpanzee optimization algorithm, and other optimizers from the literature. The enhancement in modeling accuracy by obtaining a better fitness value using MSO over other optimizers is up to 10.7% for NedStack PS6, 7.1% for Ballard Mark 5 kW, 31.5% for BCS 500 W, and 85.39% for Horizon H-500. Furthermore, a sensitivity analysis is carried out to validate the results obtained by MSO and to verify the accuracy of the developed model. Through comprehensive performance assessments, it can be confirmed that MSO is a promising algorithm for accurately estimating the parameters of PEMFC models, as it demonstrates high efficiency and robustness.</p>\u0000 </div>","PeriodicalId":12566,"journal":{"name":"Fuel Cells","volume":"25 5","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145223915","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}

A refined single-channel proton exchange membrane fuel cell (PEMFC) model, verified for grid independence, was developed. User-defined functions (UDFs) were implemented to accurately describe key processes, including electrochemical reactions, water phase change (liquid/ice), and transport phenomena. A systematic simulation analysis was conducted to elucidate the influence of operating temperature (50–70°C), anode/cathode inlet humidity (50–100% relative humidity), and gas diffusion layer (GDL) porosity (0.4–0.8) on cell output characteristics (polarization curves, power density) and internal mass transport dynamics. Concurrently, cyclic voltammetry (CV) and linear sweep voltammetry (LSV) experiments were performed to deeply investigate the electrochemical performance degradation and microstructural evolution of electrodes with varying water contents under freeze–thaw cycling. The results demonstrate that elevating the operating temperature to 60–70°C significantly enhances cell performance, primarily attributable to increased membrane conductivity and optimized water management. A synergistic optimization effect was identified between reactant gas humidity and GDL porosity. At 60°C, a combination of 75% anode humidity and 100% cathode humidity achieved an optimal balance between output performance and operational stability. Increasing GDL porosity to 0.6–0.8 effectively enhanced reactant gas transport and liquid water removal, reducing current density decay during cold start (−10°C) by approximately 50% and significantly mitigating mass transport blockage and performance degradation caused by ice formation. Freeze–thaw cycling experiments further revealed that electrode water content is a critical factor determining its durability. Flooded conditions exacerbated structural damage from freezing, leading to persistent performance decay, whereas lower water content conditions effectively preserved electrode structural integrity and catalytic activity. This research elucidates the interactive mechanisms of water–thermal–mass transport under multiphysics coupling, providing a theoretical foundation and practical design guidelines for optimizing performance and enhancing the durability of PEMFCs under complex operating conditions.</p>\u0000 </div>","PeriodicalId":12566,"journal":{"name":"Fuel Cells","volume":"25 5","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146740","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}

The pH-disparate strategy, which uses alkaline liquid fuel as anode reductant and acidified hydrogen peroxide as the cathode oxidant, has been proposed to fundamentally improve the thermodynamic voltage and cell performance of DLFCs. Herein, the prospect and challenge of hydrogen peroxide in constructing high-performance pH-disparate DLFCs are reviewed and summarized. First, the reaction mechanisms of both hydrogen peroxide oxidation and reduction on different electrocatalysts were elucidated in this review, and then the thermodynamic properties, including pH dependent thermodynamic voltage, energy density, and capacity, of different types of pH-disparate DLFCs were described in detail. Finally, we summarized the impact of the system design and operating conditions on the cell performance of pH-disparate DLFCs.

The analysis is based on a range of current densities (0.2–1.0 A/cm²) selected to reflect typical operational phases: activation, ohmic, and concentration loss sections. The results show that although higher temperature can improve cell voltage, this effect only lasts up to a certain point, with the most critical component being ohmic losses due to altered membrane hydration. This study presents a detailed computational model capable of determining the optimal operating temperature of PEM fuel cells by accounting for the physical properties of the cell materials, thus extending previous simplified calculation models. The novelty of the model lies in its quantitative consideration of the temperature dependence of not only the Nernst potential but also the activation, ohmic, and concentration losses—specifically through the temperature-dependent hydration behavior of the membrane. A key advantage of the new model is that it enables performance estimation without requiring hardware-based measurements, while maintaining a deviation of less than 5.9% from experimental results. On the basis of the calculations, a distinct optimal temperature can be determined for each current density value, which is not provided by earlier simplified models.</p>","PeriodicalId":12566,"journal":{"name":"Fuel Cells","volume":"25 5","pages":""},"PeriodicalIF":3.1,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/fuce.70021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this work systematically analyzes the reasons for the degradation of the fuel cell stack after low-temperature start-up operation with an effective area of 367 cm² and 170 cells. To investigate the root causes, systematic characterization of the catalyst layer (CL) and gas diffusion layer (GDL) was performed. Transmission electron microscopy and x-ray diffraction analyses confirmed that Pt particles exhibited increased defects and particle size at three membrane electrode positions, particularly at the hydrogen inlet/outlet, where the (111) interplanar spacing expanded significantly. Raman spectroscopy detected carbon corrosion on both anode and cathode sides after cold start, with anode corrosion being more severe. GDL permeability decreased significantly post-cold start, especially at the hydrogen outlet. Cold-start-induced water redistribution promotes ice formation at CL/GDL interfaces, triggering localized reverse polarity. Reverse polarity accelerates carbon corrosion, destabilizing catalyst supports (Pt agglomeration) and GDL pore structure (carbon powder loss).

Extending this lifespan requires a thorough investigation of their degradation mechanisms. Electrochemical impedance spectroscopy (EIS) is widely utilized to analyze SOFC degradation, with the distribution of relaxation times (DRTs) method applied alongside variations in gas flow rates at the anode and cathode, operating temperatures, and current densities. This approach helps identify the characteristic frequencies of gas concentration impedance, charge transfer impedance at both electrodes, and O²⁻ transport impedance. However, in industrial-scale SOFCs, due to overlapping time constants of gas conversion impedance and gas diffusion impedance, the DRT method struggles to differentiate between gas conversion and gas diffusion impedance within gas concentration impedance. Moreover, gas concentration impedance at the cathode can only be identified at low O₂ concentrations. To overcome these limitations, this study proposes a gas concentration resistance fitting model for industrial-scale SOFCs under limited gas supply conditions. The proposed model effectively isolates gas concentration resistance while addressing the shortcomings of the DRT method.
