A water flooding diagnostic approach is proposed based on the uniformity of current density distribution. This is achieved by employing a dead-ended PEMFC equipped with a 36-subarea current density detection plate for high-accuracy positioning. Experimental results demonstrate a positive correlation between the standard deviation (SD) of current density distribution and cell water content, following the linear equation y = 0.093x + 59.22 (R2 = 0.955). Comparative tests show that constant voltage mode stabilizes water content at 78% ± 2% and SD at 380 ± 5 mA/cm2 to suppress flooding, whereas constant current mode leads to excessive water accumulation (92.2%) and a sharp SD surge to 619.0 mA/cm2, causing voltage collapse. Temperature tests (30–60 °C) confirm that elevated temperatures increase the visible water content inside the cell due to the condensation of water vapor, thereby enhancing current density inhomogeneity. This study establishes SD as a quantitative indicator for flooding severity, enabling precise localization of local flooding and providing critical guidance for PEMFC water management optimization.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"14 8","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752554","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}

To address these limitations, the proposed system integrates a Tubular Solar Still with an Evacuated Tube Solar Collector to enhance heat transfer and evaporation performance. A hybrid Physics-Informed Artificial Neural Network model is employed to accurately predict system performance based on environmental and operational parameters.

This mismatch accelerates degradation, reduces cycle life, and increases thermal stress within battery systems. Supercapacitors, characterised by high power density and excellent cycle stability, can rapidly handle such transient loads but lack sufficient energy density for standalone use. To address this limitation, hybrid energy storage systems (HESS), integrating batteries and supercapacitors, provide a complementary solution by balancing energy and power requirements. In this architecture, batteries supply sustained energy for driving range, while supercapacitors manage peak power demands, thereby reducing battery stress and improving overall system efficiency and lifespan. This review systematically examines various HESS topologies and their operational characteristics, highlighting trade-offs in complexity, controllability, and performance. It further analyses existing energy management strategies and identifies gaps in achieving optimal power coordination under dynamic conditions. Emphasis is placed on emerging intelligent control approaches, including advanced optimisation and data-driven methods, to enhance real-time energy management.

The results reveal a significant reduction in the band gap under 4% compressive stress, reaching 1.9 eV for CsGeF3 and 1.32 eV for CsSnF3, which improves their suitability for visible-light absorption. Additionally, the absorption coefficient in the visible range is strongly enhanced, indicating better light-harvesting capabilities. Photovoltaic efficiencies, evaluated using the spectroscopic limited maximum efficiency model, increase from 10.96% to 23.28% for CsGeF3 and from 25.19% to 30.64% for CsSnF3 under 4% compression, confirming their promising potential as solar absorbers.

A steady-state model based on energy conservation and PEM equivalent resistance was also established to extend the analysis to PEM electrolyzer series–parallel configurations. The results show that PV output power governs both hydrogen-production capacity and energy-utilization efficiency. Doubling the maximum PV output power increased hydrogen production by approximately 101.5%, while operation above 40% of the maximum PV output maintained high energy utilization. The number of series-connected PEM electrolyzer cells mainly determines voltage matching: too few cells lead to overvoltage losses, whereas too many cells result in insufficient single-cell voltage and electrolysis failure. In contrast, parallel PEM electrolyzer branches regulate current–density distribution and internal losses. Increasing the number of parallel branches improved hydrogen production and energy utilization and reduced specific electricity consumption, although with diminishing returns. Economic analysis shows that the PEM stack accounts for 88.2% of CAPEX, making four- to six-branch configurations more practical for balancing efficiency, cost, and system scale. Overall, system performance depends on matching PV power-supply capability with PEM electrolyzer load demand.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"14 7","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148466839","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}

By combining liquid cooling, a micro heat pipe array (MHPA), and an aerogel insulation layer, the system enhances heat dissipation during normal operation and suppresses thermal runaway (TR) propagation under abuse conditions in large-format lithium-ion battery modules. A full-scale 3D multiphysics model was developed and experimentally validated to investigate TR initiation and propagation in a four-cell 300 Ah LiFePO4 battery module under different thermal management configurations. Results show that liquid cooling delays TR onset but cannot prevent propagation, whereas the aerogel barrier blocks propagation but advances TR initiation. The proposed ATM&PTI architecture synergistically enhances axial heat extraction and lateral thermal isolation, delaying TR onset to 7108 s and achieving complete propagation suppression. Sensitivity analyses further define the safe-operating design window: for a 3 mm barrier, the critical thermal conductivity and coolant flow rate required to block propagation are 0.07 W m−1 K−1 and 175 mL/min, respectively.

The presence of different metals coupled with nickel significantly influences the reforming process, for example, producing high hydrogen yield (>100 mmol g−1plastic), defined H2:CO ratio (between 1.96 and 3.41), or heavy catalyst coking. For example, the Ni-Cu/Al2O3 catalyst produced a H2 yield of 99.13 mmol g−1plastic, H2:CO ratio of 3.41, but with high catalyst coke deposition of 15.76 wt%. Whereas, the Ni-Mg/Al2O3 catalyst gave a H2 yield of 92.19 mmol g−1plastic, H2:CO ratio of 2.56, and moderate coke deposition of 6.60 wt%. The Ni-Mn/Al2O3 and Ni-Mo/Al2O3 catalysts gave hydrogen yields of 87.55 and 82.26 mmol g−1plastic, respectively. Bimetallic catalysts containing no Ni, such as Fe-Co/Al2O3, and Co-Cu/Al2O3, showed reduced H2 yield and H2:CO syngas ratio. The results highlight the critical role of active metal choice and loading in maximising hydrogen production and minimising catalyst coking. Nickel remains the most effective reforming metal, while carefully designed bimetallic catalysts, particularly those containing Co, Mo, or Mg, offer targeted gains in hydrogen selectivity, targeted H2:CO ratio, or catalyst coke resistance.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"14 7","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ente.70573","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148462897","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}

Herein, we report a facile strategy combining hydrothermal and annealing processes to fabricate high-performance electrocatalysts for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), respectively. Notably, the In(OH)3 cubes loaded with Ru NPs (denoted as Ru-In(OH)3/CC) exhibit excellent HER performance in an alkaline medium, achieving a low overpotential of 135 mV at a current density of 50 mA cm−2. Meanwhile, the hydrothermally derived RuO2-In2O3/CC catalyst delivers an overpotential of 380 mV at a current density of 50 mA cm−2 for OER, outperforming most recently reported catalysts and commercial RuO2. Such superior electrocatalytic performance is attributed to the uniform dispersion of active Ru NPs enabled by the In(OH)3 support and the enrichment of RuO2 on the surface of In2O3. Furthermore, the two-electrode electrolyzer constructed with Ru-In(OH)3/CC (cathode) and RuO2-In2O3/CC (anode) requires only a cell voltage of 1.58 V to deliver 10 mA cm−2 for overall water splitting and maintains a stable current output for 20 h.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"14 7","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148462902","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}
